• Output isolating unit,
• Digital input unit,
• Output unit,

• Pulse output unit,
• Keyboard and LCD display unit.
The input signals in input adaptor unit shall be generator terminal voltage (from VT),
generator current (from CT), field current and the output signals in the unit shall be the
conditioned input signals for sampling.
Active/reactive transducer unit shall be used to simulate the active and reactive
component of the generator current.
The analog input unit shall be used for generator voltage rectification and filtering,
synchronous signal pretreatment, frequency measuring signal generating, active/reactive
component adapting. The output of this unit shall be fed to the main central control unit.
Input isolation unit shall be used to isolate input signals such as generator status, control
operation
Digital input unit shall be used to isolate and convert the 24 V level signal (already
isolated) to 5 V level for CPU.
77
Digital output unit shall be used to opt-isolate CPU control and output signals.
Output isolating unit shall be used to isolate the signals from digital output unit via relays
for logic control circuit.
Central Processing Unit (CPU) shall be the core of the regulator. The following functions
shall be done here in this unit namely set-point value, PID filtering, trigger pulses,
channel follow-up, series communication, limitation and protection, parameter display,
parameter setting, parameter storage.
Pulse output unit shall be used to output trigger pulses to converter cubicles. The trigger
pulses shall be amplified in the final pulse unit in converter to trigger the thyristors in the
cubicles.
Keyboard and LCD display unit shall provide a friendly man-machine interface for users.
Data displaying, parameter modifying and fault recording of the excitation installation
and the communication with host computer can be realized through the interface.
The excitation cubicle shall be designed for local/remote control and shall include as a
minimum the following: -
• Pushbuttons: lamp test, reset, excitation ON, excitation OFF (with protection
cover)
• Switches: voltmeter phase switch (if applicable), AUTO/MANUAL mode switch
(with centre position), AVR Raise/Lower (with centre position), Remote/Local
control key selector switch.
The selection between the local or remote control mode shall be done by means of a key
protected switch. The key can only be removed in the remote position, and this function
shall disable the front door pushbuttons in the normal mode of operation. During
commissioning if specific operations such as maintenance are required, the key shall be
necessary to enable local control mode. This will, in turn, disable the remote I/O.
6.3.3 Manual Channel (Field Current Regulator):
The manual control mode shall be used as test facility (e.g. during commissioning or
maintenance of the equipment) or as back-up control mode in case of incorrect of the
AVR (e.g. loss of actual value, due to potential transformer failure)
When operating in the manual control mode, excitation controls the field current of the
synchronous machine by means of a field current regulator FCR. The actual value of the
field current it is taken inside of the excitation cabinet in order to ensure a control loop
which is independent of external measuring circuits and/or transducers.
The set-point function for the manual control mode has the similar functions as the set-
points as well as two different running times can be adjusted. When operating in manual
control mode, the set-point for field current may be controlled by raise of lower
commands.
An immediate reset input is provided in order to avoid over voltages caused by reactive
load rejections while operating in the manual control mode. If the machine breaker trips,
a pulse command is applied to the reset input which sets the field current immediately
78
back to pre-set value which normally corresponds to 90..100% of the no-load field
current of the synchronous machine.
The resulting error signal at the output of the set-point is applied to a filter circuit with PI
characteristics. The optimum settings of this PI-Filter are achieved by setting the DC
gain Vo, the proportional gain Vp and the integral time constant Ta.
6.3.4 Follow-up Control :
An automatic follow-up control ensures a surge-free change-over from automatic (AVR)
to manual control mode. When operating in the AVR mode, the difference signal
between automatic channel output and manual control output is used for the automatic
follow-up. This difference signal is also used as a feedback signal for the channel which
is presently not in operation and therefore in open loop condition. This is necessary for a
stable balancing between the AVR and the FCR.
In a double channel system the inactive channel follows automatically the leading
channel.
The AVR shall be provided with over & under excitation limiters. The intervention of
the limiters shall not cause perceptible deviations or oscillations of the generator active
& reactive power. Such devices shall allow the regulator to reduce the excitation voltage
to zero in order to prevent over voltage in case of operation, under line reactive load
conditions and over speeding of the unit. The characteristics of the under excitation
limiting curve shall match the static and dynamic stability curves of the generator.
The field current limiter shall act on AVR with a time delay so as not to disturb transient
response of the system during voltage dips/faults. A slip stabilizer unit shall be provided
to surpass the low frequency power oscillation during the operative conditions.
The AVR shall be equipped with a sensitivity-adjusting device and with adjustable
voltage droop compensation (compounding). The voltage regulating system shall include
device for improving the damping of active electromechanical oscillations. These
devices shall operate to supplement the voltage regulation action by addition of an
additional control signal into the excitation system input. This supplemental input signal
shall influence the excitation system a.c. to cause a change in field current of the
machine for stabilised operation.
After, the generator voltage attaining initial maximum value neglecting the instantaneous
rises following any load rejection upto 100% of rated load, DVR shall restore the
generator terminal voltage to a value not more than 10% above or below the voltage
being held before load rejection and shall maintain the voltage within these limits
throughout the period of the generator over speed.
The voltage setting device provided shall be of the solid-state digital type having a range
of + 10% for local & remote control and indication. For testing purposes setting of 10%
to 115% shall be adjustable at the AVR cubicle.
The excitation system shall be designed for manual and automatic operation with
provision for manual to auto changeover and vice versa. The change over from automatic
to manual control shall be performed automatically following a failure of the regulator
79
when operating on automatic control. The generator voltage shall be controlled with in
the range of + 10% of rated voltage. A static follower shall be provided so that, in the
event of change over from automatic to manual control or vice versa, it prevents the
excitation current from deviating more than 5% of no load excitation current under
steady state conditions. An alarm and visual indication shall be provided to indicate
change from "AUTO" to 'MANUAL'. The automatic and manual control circuit shall be
fully independent. Local & remote control shall also be possible.
