Global SCADA System Concept

• IEC 60870-5-104, cca 40.000 indications,

approx. 8.000 measurement

• Data exchange with adjacent operators -

TASE.2

• Real-time databases, identical in NCC and

in RCC (Multisite)

• Mechanisms of regional and local

authorizations based on the type of the user

• Historical database

• Migration and parallel operation of old

and new system

EMS functions:

•In real time and in a study mode

•Size of the network model: 252 stations of internal

and external networks, 430 lines, 506 transformers,

135 generators, approx. 7.200 measurement,

approx. 8.700 indications.

•EMS functions calculations over the entire model

of the network in real time within 2 seconds

CF (Congestion Forecast):

•Automated production of the 24 hour feasibility

test, 24 hour planned losses and 24 hour NTC

value calculations for the crossborder exchange

•Automated production of IDCF files

•Making DACF files on demand

Energy Management System - EMS

• Installed in the NCC and ECC

• Production management system within

Croatian TSO domain of responsibility :

– AGC function

– ED function

• Regulation power plants (3) + Cetina river

catchment

• Control area / block

• System Ancillary services market

Automatic Generation Control – AGC

• Landys&Gyr Advance

• Installed in a dual configuration using

Hyper-V virtualization

• Connected to C2000 by using oracle

DB links

• Support for virtual measurements

• Powerful operational reporting

• Data source for other information

systems

– MMS Accounting and

Settlement

– DWH

– etc.

New Metering System

Student modul:

• Provides identical environment for

power system operators training as in

on-line SCADA/EMS system, but

without affecting the system itself

• Users can learn how to manage the

power system during the disturbance,

in exceptional circumstances and

during the establishment of normal

network state

Instructor modul:

• Provides facilities for the preparation

of training, training control and post-

training analysis

New Software Systems

Market Management System

• The integration of data from

different source systems

• Common Data Model (CDM)

• Reporting functions

• Advanced analytics

Data Warehouse (DWH)

• Globaly segmented network –

VLANs across all locations

• Network traffic filtering – allowed

only necessary between segments

+ intrusion detection system (IDS)

• Central network management and

security mechanisms

• Safety rules defined on the basis of

the information security and

information risk assessment

analysis (ISMS according to ISO

27001)

Network and Security

• One of the most important ICT projects in Croatian TSO

• Cooperation of Croatian TSO, KONČAR, Croatian companies and

research institutions

• Complexity of comprehensive technical solutions and great

technological breakthrough

• Solid foundation for future development and improvement of the

overall system

• A significant contribution to the safety and effectivness of power

system management
