Customer: European Power Transmission System Operator
Industry: Power Transmission
Business Case:
The power transmission system (400kV) is interconnected with the European grid using tie-lines, which connect certain boundary substations (Extra High Voltage Substations), with corresponding substations of the neighboring systems. The importance of the safe operation of these interconnections was high for the stability of the domestic system, the European system, and the operation of the electricity market. Therefore, events occurring at these lines and events generally at the substations where these lines were placed, must be accurate, fast, thoroughly analyzed, and assessed, between the two involved operators.
The scope of the system included
The Solution:
PDCAS was based on Kalkitech Power Systems Enterprise Suite (PSES) at the control center and SYNC3000Substation Disturbance Record (DR) collector/data concentrator at each substation. The system utilized the decentralized architecture wherein each substation had one SYNC3000 with several terminal servers (SYNC2000) along with the required data network active and passive equipment (fiber optic cables, patch panels, Ethernet switches, routers) were installed. The SYNC3000 was equipped with drivers/adaptors which enabled communication with different types and brands of grid devices, including ABB, Siemens, Areva, and SEL. The drivers were based on licenses, collect disturbance data from various protocols including ABB SPA, Alstom Courier, IEC60870-5-103, IEC61850, SEL ASCII, and Fast Message Protocols as well as various custom Modbus implementations. Furthermore, SYNC 3000 automatically transforms received disturbance records to COMTRADE format and name and merges files according to the IEEE-PES-PSRC report.
Key Benefits:
By implementing the solution, the power transmission system operator was able to achieve the following benefits:
