The control and protection system of HVDC and FACTS device must be brought into the real-time simulator for pre-commissioning and performance verification. The rapid development of digital real-time simulators in power systems provides the solution to the real-time testing of control and protection system of HVDC and FACTS device. With practical examples, the principle and process of the digital real-time simulators on real-time testing of control and protection system of HVDC and FACTS are presented. In addition, the principle and aplication of hybrid real-time simulators and the advanced real-time integrated hybrid simulator are proposed in this paper. Hybrid real-time simulator is an economic and efficient way to handle large-scale testing systems in real time. The test result of the real-tine simulator is verified by the test resull plant control equipment.
