VERIFICATION OF HYBRID REAL TIME HVDC SIMULATOR IN CHEJU-HAENAM HVDC SYSTEM

In this paper Hybrid Real Time HVDC Simulator for both operator's training and researching in Cheju-Haenam HVDC system is proposed and its performance is verified by RTDS(Real Time Digital Simulator), EMTDC(Electro-Magnetic Transient system for DC), PSS/E(Power System Simulator for Engineering), and experienced scenarios. The main objective of this paper is to represent the strategy in development of the KEPCO hybrid HVDC simulator for Cheju-Haenam HVDC system. This simulator consists of two DC stations, DC cables, external digital/analogue controllers, control desk for education, and AC networks. In cases of both startup/shutdown and normal state operations, the suitability of it for operator's education is tested. Also the dynamic performances of it are verified.
