3.1 There were no major Grid Disturbances in the Southern Regional Grid
during the year 2006 – 2007. However, the system occurrences and minor trippings
that took place in the constituent systems were discussed in detail, regularly in the
Protection Sub-Committee meetings and necessary rectification / remedial
measures suggested by the Protection committee were taken up for implementation
by the constituents to avoid its recurrence.
3.2 The Protection Sub-Committee of SRPC analyses the Grid Disturbances,
System Occurrences and other trippings that occur in the Southern Regional Grid
and suggests measures to avoid their recurrence. The functions of the Protection
Sub-Committee in brief are as follows:
a) Analysis of the Grid Disturbances, System Occurrences and other trippings and
to suggest measures to avoid their recurrence.
b) Coordination of settings of protective relays in the Regional System to maintain
the security of the Grid.
c) Periodical review of under frequency load shedding schemes, df/dt load
shedding schemes and other protection schemes adopted in the Grid.
d) Review of the implementation of recommendations made by the inquiry
committee of the grid disturbances in the region concerning to above matters.
e) To suggest, discuss and implement special protection schemes to take care of
major loss of import / generation so as to ensure security of the Grid.
29
During the year 2006 – 2007, the Protection Sub Committee met twice (1st
and 2nd
Protection Sub Committee meeting on was held on 25.07.2006 and
08.12.2006 respectively). The 2nd
Protection Sub Committee meeting was
preceded, by the meeting of the Working group on Protection.
3.3 The following issues were deliberated/ implemented by the constituents in
the Protection Committee of SREB/Protection Sub-Committee of SRPC during the
year:
a) The load relief obtained at different settings of flat under frequency
relays provided in the constituent systems was reviewed for their
correctness during system occurrences / disturbances and
necessary remedial measures recommended by the committee
were implemented by the constituents.
b) The operation of df/dt relays in the constituent systems was
reviewed periodically. The operation of this scheme and the
quantum of load relief obtained is also being monitored regularly for
its effectiveness.
c) Carrier Protection in the Kaiga corridor (Nagjhari-Kodasalli on
17/08/2006, Kadra-Kodasalli on 18.08.2006, Kaiga-Kadra & Kaiga-
Kodasalli on 19.08.2006) has been installed by KPTCL.
d) Bus Bar protection at Somanahalli 220 kV substation has been
commissioned by KPTCL on 08.09.2006.
e) Kaiga have implemented an inter trip scheme at Kaiga generating
station to avoid over loading & tripping of Kaiga – Guttur lines
whenever the power flow gets diverted towards Kaiga due loss
evacuation lines between Nagjhari and Hubli stations. With the
above scheme 220kV Kaiga – Kadra & Kaiga – Kodasalli lines
would trip, whenever the current reaches 750 amp /1.5 sec on
Kaiga-Guttur 220 kV line. The tripping is interlocked with the
availability of one of the 400 kV Kaiga-Narendra lines.
30
f) Islanding scheme for Kaiga generating station is under discussion
in the protection sub committee. The scheme considers islanding of
Kaiga Units I&II along with 250 MW of KPTCL load.
g) Islanding scheme for NTPC, Ramagundam STPS is under
discussion in the protection Sub-Committee. The scheme considers
islanding formation with one unit of 500 MW and one unit of 200
MW of Ramagundam along with radial loads of Andhra Pradesh
connected to ICTs at RSTPS to avoid total shutdown of RSTPS
during grid disturbances. Subsequently APTRANSCO proposed to
form an Island for Hyderbad with Ramagundam generators. Now
the discussions are on for designing an islanding scheme of
Ramagundam generators with local loads as well as Hyderabad
loads of APTRANSCO.
h) Islanding scheme for NTPC, Talcher STPS is also under discussion
in the protection sub committee. The scheme considers the
disconnection of Talcher Stage –II Units from ER grid during under
frequency conditions and forming island with Southern Region
through Talcher-Kolar HVDC link.
i) Special Protection Scheme (SPS) for 2X1000 MW Kudankulam
Nuclear Power Plant (KNPP) is under discussion in the protection
committee. 1000 MW generators at KNPP is biggest size generator
in Southern Region whose outage could pose frequency instability.
SPS for KNPP is being worked out to care of contingency of loss of
generation due to tripping of one/ two units. A special working
group was formed in the 1st Protection Sub Committee meeting and
was entrusted with task of designing the logic scheme of the SPS
with various micro level engineering options. The special working
group submitted its report for approval by Protection Sub
Committee in its 2nd
meeting held on 08.12.2006. The sub
committee agreed to the recommendations of the special working
group except for implementing agency at Kudankulam, so the issue
was put up to TCC/SRPC for their consideration. The matter is still
under consideration of TCC/SRPC.
31
j) Up gradation to 400 KV operation of Kaiga-Guttur DC link was
under taken. The Kaiga-Guttur circuit-II has been put into regular
operation from 14.07.2006 after changing all the defective
insulators. Similarly circuit-I was charged 400 KV level w.e.f.
07.03.2007 after changing all the defective insulators.
k) KPCL have implemented a selective tripping scheme at Nagjhari
generating station to save the simultaneous tripping of all units at
Nagjhari in the event of Nagjhari having been cut-off from load
centre Hubli on account of fault & operation of reverse power
protection taking place at Kaiga, tripping Kaiga – Kadra / Kodasalli
lines and thus leaving Nagjhari generators without any evacuation.
A revision in settings on the above scheme suggested by the
protection Sub Committee was implemented by KPCL on
10.08.2006.
l) A review meeting was held at CEA, New Delhi, on 22-12-2006 to
discuss the revised tripping scheme for Talcher STPS II units
during outage of Talcher – Kolar link, proposed by NTPC. The
implemented scheme was based on 450 MW jerk to the ER system
whereas the revised scheme is based on the presumption that the
ER-NR-WR grid bear a jerk of 1100 MW after commissioning of
Tala Transmission system. The meeting was taken by Member
(PS), CEA wherein it was agreed that:
o Revised scheme to be designed to in such a way that the
sudden impact on NER-ER-WR-NR system is less than
1000 MW
o Scheme should cause minimal trippings of Talcher II units.
The unit tripping alongwith run back of other unit(s) could
be implemented in such a way that the total relief comes in
about 4-5 seconds
o NTPC may look into the possibility of designing the scheme
by measuring inrush into ER grid and building the scheme
logic accordingly.
32
m) In view of the system occurrence in Karnataka on 01.11.2006 at
14.08 hrs, wherein one Kaiga Unit got poisoned out, a special
working group was formed in the 2nd
Protection Sub Committee
meeting held on 08.12.2006 for reviewing the relay settings in
Kaiga related corridor. The special working group held a meeting at
Kaiga on 8th and 9
th Feb 2007 and has submitted its report for
approval by Protection Sub Committee.

4.1 ENERGY ACCOUNTING: Availability Based Tariff (ABT) has been implemented in Southern
Region w.e.f. 1st January 2003. Consequently, accounting of energy for the
SR grid is being done by SRPC Secretariat regularly in line with CERC
guidelines / directives. The energy accounting involves preparation of
weekly UI, Reactive Energy Accounts and monthly Regional Energy
Accounts.
4.1.1 Weekly UI and Reactive Energy Accounts:
4.1.1.1 In line with the order of CERC, weekly accounts of Unscheduled
Interchanges (UI) and Reactive Energy are to be prepared and issued by
SREB/SRPC Secretariat every week in a time bound manner. Under the
ABT regime, each day is divided into 96 time blocks of 15 minutes each.
The schedules of generation by each Inter State Generating Station (ISGS)
and drawals by each beneficiary constituents for each time block is
compared with their actual generation / drawal for each block (computed
from the block wise reading of SEMs on all feeders). The charges for
deviation between actuals and schedules are computed on the basis of
frequency linked UI rates stipulated by the CERC from time to time. The
34
weekly UI accounts are compiled from the block wise data for all the 7
(seven) days ( Monday to Sunday ) of a week.
4.1.1.2 Weekly Reactive Energy account is prepared from the reactive
energy injected / drawn by the constituent beneficiaries with reference to
prevailing voltage conditions. Incentives for reactive energy injection at low
voltage and drawals during high voltage conditions and penalty for reactive
energy drawal at low voltage and injection during high voltage conditions
are levied at rates specified by CERC. The Reactive Energy account is also
compiled, like UI accounts, from the SEM readings every week.
4.1.1.3 UI and Reactive accounts were prepared and circulated to SR
constituents on weekly basis, as per the provisions of ABT orders and in
pursuance of CERC directions, with the soft copies of the computed files
uploaded to website so as to enable downloading by the SR constituents.
4.1.2 Monthly Regional Energy Accounts (REA)
4.1.2.1 The monthly REA, issued by SRPC, gives the details of energy
scheduled by beneficiary constituents from ISGSs within and outside the
region. The REA enables the Central Power Utilities to raise the bills on
beneficiaries for charges relating to capacity, scheduled energy, incentives,
transmission, RLDC etc. The monthly REAs, inter-alia comprise details on
the following:
i. Computation of Availability and PLF of thermal ISGSs covered by ABT.
ii. Energy scheduled to constituent beneficiaries from ISGSs for payment of energy charges.
iii. Energy scheduled by beneficiaries from ISGSs beyond target PLF for the purpose of payment of incentives to ISGS.
35
iv. Computation of weighted average percentages for the purpose of payment of Regional Transmission charges and RLDC charges.
v. Details of Intra-regional and Inter-regional scheduled bilateral exchanges and wheeled energy on short term open access.
vi. ESCOM / DISCOM wise details for Payment of Capacity / Energy charge and Incentive, wherever applicable.
4.1.2.2 The provisional REA for the current month and the final REA for the
previous month were issued latest by the 6th of each succeeding month.
4.2 UI CHARGES FOR INTER-REGIONAL EXCHANGES WITH
WESTERN & EASTERN REGIONS
4.2.1 At the time of implementation of ABT in SR, viz. 1.1.2003 it was
decided that the UI for inter-regional exchanges with WR will be settled at
the rates of the respective regions, i.e the UI receivable by the exporting
region and the UI payable by the importing region will be at their respective
frequencies. The difference amount between UI payable by the importing
region and receivable by the exporting region will be shared at 50:50 by the
two regions.
4.2.2 In the case of Eastern Region, the weekly UI accounts for inter-
regional exchanges between ER & SR are being prepared w.e.f. 1st April
2003, viz. the date of implementation of ABT in Eastern Region. EREB vide
their communication dated 1st April 2003 had intimated that UI for ER-SR
exchanges will be calculated at ER frequency only and accordingly, the UI
charges for inter-regional exchanges between ER and SR were being
computed at Eastern Region frequency. Subsequently, EREB proposed
vide letter No. EREB/COM-II/GEN/2004/ 2736-41 dated 28th May 2004 that
inter-regional UI between ER & SR be on respective regional frequencies.
EREB’s proposal was considered by SREB in a Special meeting of TCC
36
held on 23rd
August 2004. On the recommendations of TCC, the proposal
was agreed to by SRE Board in the 136th meeting and implemented with
effect from 6th September 2004, for which EREB’s concurrence was also
conveyed.
4.2.3 In view of the above, for exchanges of UI power with ER as well as
WR, amounts corresponding to respective regional frequencies are being
charged. The difference amount between UI payable by the importing
region and receivable by the exporting region were shared at 50:50 by the
two regions.
4.3 MEETINGS OF THE COMMERCIAL COMMITTEE
222nd
meeting of Commercial Committee of SREB was held in April
2006.Subsequently,Southern Regional Power Committee (SRPC) was
established and in line with Conduct of Business Rules, 2006 of SRPC,
Commercial Sub- Committee was reconstituted with representation from
member constituents of SRPC. Meeting of Commercial Sub-Committee of
SRPC were conducted in line with the provisions of revised Indian
Electricity Grid Code (IEGC) issued by Central Electricity Regulatory
Commission (CERC), effective from 1st April 2006. Accordingly, 1
st and 2
nd
meeting of Commercial Sub-Committee were held during the year 2006-07,
for audit of regional UI account and regional reactive account for the period
from 01.04.2006 to 03.09.2006.

Reverse power protection at Kaiga generating station:
Whenever the power flow gets diverted towards Kaiga due to loss
of evacuation lines between Nagjhari and Hubli stations, the increased
power flow on Kaiga – Guttur lines which are operating at 220kV level at
present, results in overloading of these lines with added generation of
42
Nagjhari, Kadra & Kodasalli generating stations and was resulting in
cascade tripping of Kaiga – Guttur lines most of the times.
Thus Kaiga gets islanded along with the above hydel generating
stations and the Units at Kaiga were tripping on loss of evacuation lines.
Earlier Kaiga was provided with a protection scheme to trip Kaiga – Kadra &
Kaiga – Kodasalli lines by sensing over load conditions on Kaiga – Guttur
lines. However the scheme failed to operate certain times due to racing of
relays.
Now Kaiga have implemented an additional protection scheme at
Kaiga generating station so as to trip 220kV Kaiga – Kadra & Kaiga –
Kodasalli lines, whenever the reverse current exceeds 600 amps for 1.0
sec. or 900 amps for 0.2 sec on these lines due to diversion of power flow
from Nagjhari, Kadra & Kodasalli generating stations towards Kaiga and
thus tripping of Kaiga – Guttur lines and islanding of Kaiga generating
station could be avoided.
Selective tripping scheme at Nagjhari generating station:
Whenever 220kV Nagjhari– Hubli lines 1, 2, 3 & 4 trips, it was
resulting in diversion of power flow from Nagjhari, Kadra & Kodasalli
generating stations towards Kaiga and leads to tripping of Kaiga – Kadra &
Kaiga – Kodasalli lines on reverse power protection provided at Kaiga. This
further results in islanding of the Units at Nagjhari, Kadra & Kodasalli
generating stations and trips due to lack of evacuation lines. KPCL have
implementing a scheme to trip the selected generators at Nagjhari
generating station by sensing power flow levels on Nagjari – Kodasalli lines
so as to limit the power flow on these lines towards Kaiga and thereby
avoid the tripping of Kaiga – Kadra & Kaiga – Kodasalli lines on reverse
power protection at Kaiga and which would in turn help in avoidance of total
loss of generation at Nagjhari, Kadra & Kodasalli generating stations. The
scheme helps in minimizing further disturbances and in improving the
system security of Southern Regional grid.
Power relays are installed on Nagjhari – Kodasalli line. Whenever
export through this line is more than 150 MW and less than 250 MW unit
1,2,4 & 5 trips sequentially with 0.1, 0.2,0.3and 0.4 seconds delay
43
respectively. If export is more than 250 MW unit 3,6 trips simultaneously
with 0.1 delays.
5.5 ISLANDING SCHEMES IN SOUTHERN REGION
Due to relatively even distribution of load and generation, the
islanding schemes are provided only in TN system, as an ultimate backup
during very low frequency conditions in Southern Regional grid. In few other
generating stations in the Region, the generators go on house load under
low frequency conditions. The details of the islanding schemes and house
load operation of generating units available in SR grid is furnished in the

5.6 DATA FOR MERITORIOUS PRODUCTIVITY AWARD:
The daily peak hour generation data of the thermal power stations
of Southern Region were collected from the power station authorities on
completion of every calendar month. The data were verified, compiled and
forwarded to OM Division, CEA, New Delhi for consideration for the
meritorious productivity award. The data on planned maintenance schedule
and actual maintenance taken up on the thermal units of Southern Region,
during the year 2006 - 2007 were also collected from the power station
authorities and compiled and sent to OM Division, CEA, New Delhi for
consideration of thermal stations for the award.
5.7 SYSTEM STUDIES:
The System Studies Sub Committee in which all the members of
SRPC represented is entrusted with the task of carrying out studies for
assessing quantum of capacitor requirement in the region, operational load
flow studies or any other technical studies referred by the SRPC/TCC.
Power System Studies for assessment of shunt compensation
required in the Regional grid is done for the annual peak load conditions.
The capacitor requirement is assessed with a view to maintain system
voltage at all the buses in the range of 0.90 to 1.05 per unit. The results of
the studies are brought out in the form of a report, which forms basis for the
constituents in planning the capacitor installation programme in their
respective systems.
During the year 2006-07, 24th meeting of System Studies Group
and 1st meeting System Study Sub-Committee was held on 19.04.2006 and
28.07.2006 respectively to finalise the capacitor requirement for the year
2006-07. The Report on the requirement of Shunt Compensation for March
2007 conditions was issued during August 2006. Action was also initiated to
assess capacitor requirement for the year 2007-08. In this connection,
preliminary data was collected from the constituents for conditions
prevailing on 29.03.2006 at 19:00 hrs in Southern Region. Base Case
45
Studies were carried out and circulated to the members of the System
Study Group for their comments.
The Power Map of Southern Regional Grid showing all 400 kV and
220 kV lines including all the inter-state / inter-regional lines was
periodically updated.
5.8 POWER SYSTEM STABILIZER TUNING:
In the 136th SRE Board meeting held at Hyderabad on 9
th
November 2004, the Board agreed to the carrying out of analytical studies
related to PSS tuning in SR and for forming a core group for this purpose.
For funding of these studies a tentative amount of Rs. 10 lakh, to be shared
equally by all the constituents was approved. The scope of the analytical
studies, among others, was to suggest need or otherwise, of PSS tuning of
the generators in SR. It was approved that the studies could be carried out
either through IISc, Bangalore or IIT, Mumbai, who carried out the studies in
case of WR, as per the needs.
In this context, IISc, Bangalore was approached. They agreed to be
associated for carrying out the analytical studies and also suggested for
involving Prof. R. Ramanujam of Anna University, Chennai and personnel
from CPRI Bangalore.
The core group for PSS tuning in SR was formulated and the first
meeting was core group was held 4th April 2005 in conference hall of SREB
wherein constituents agreed to provide all the relevant data for the studies.
An Interaction between Member Secretary, SRPC and Prof. R.
Ramanujam of Anna University, Chennai was held on 19.05.2006. Prof. R.
Ramanujam suggested the following methodology for doing the study for
PSS tuning in SR:
o Identify two to four base cases to reflect the operating conditions of
SR
o One to two contingency analysis on each base case to be done
46
o Eigenvalue analysis for each base to identify the least damped
mode. If any one of the rotor modes are very close to imaginary
axis then PSS is suggested
o Arrive at PSS parameters for each case and freeze on the one that
is best compromise for all cases identified above
o Perform Transient Stability analysis runs with PSS to check for
large-signal performance.
Further interaction is going on between IISC Bangalore and SRPC
secratariat.
