Real-Time Testing for Control and Protection Systems of HVDC and FACTS

The development and application of real-time testing for control and protection systems of high voltage direct current(HVDC)and flexible AC transmission system(FACTS)is described. The content of real-time testing and the requirement of real-time testing for time-step, equivalent system and simulation model are analyzed. With the analysis for the characteristics of analogue simulator and digital real-time simulator, the principle and application of hybrid real-time simulators are presented. As an economic way to handle large-scale testing systems in real time, the advanced real-time integrated hybrid simulator is proposed. further investigation of the real-time interaction and data exchange between the electromechanical stability program and the electromagnetic transient program is explored, and a real-time digital hybrid interface which utilizes the voltage prediction techniques to correct the one electromechanical time step delay in the real-time interaction has been developed.
