Real-time digital power system simulation based on wave digital filters for protective relays and HV

Abstract This paper describes the use of wave digital filters tool for a complete simulation software package. A brief in real-time digital and hybrid power system simulation, description of wave digital filters is performed, and typical emphasizing protective relays and HVDC / FACTS control applications are shown, equipment testing. Practical results are shown, confirming that wave digital filter methodology is an adequate tool for studying power system electromagnetic transients. 11. THE NEED FOR REAL-TIME SIMULATION
