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
Operator Training Simulator – OTS
INTELLIGENT VISUALIZATION INTELLIGENT ALARM HANDLING
LIGHTNING LOCATION SYSTEM
WIND POWER MANAGEMENT
New Software Systems
• 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
