STATCON과 송전계통의 동적응동 분석을 위한 EMTP 시뮬레이션 모델

EMTP SIMULATION MODEL TO ANALYZE DYNAMIC INTERACTION BETWEEN STATCON AND TRANSMISSION SYSTEM

This paper dscribes a detail simulation model with EMTP (Electro-Magnetic Transients Program) which is very effective to analyze the interaction between the ac transmission line and STATCON (static condenser). The SATCON was represented by two voltage-source converters connected in parallel and sharing an energy storage dc capacitor bank. The voltage source converters was modeled with ideal gate turn-off switches. The power system was represented by a detail generator model and a distributed tramnsmission line model for detail performance analyses. Analysis results show that the conceived simulation model is very effective to analyze the interaction between the ac transmission line and STATCON, and to evaluate the performance of STATCON.
