Closed loop test platform for SVC controller based on RTDS

Real time test is a necessary step for the control device of equipment before it is installed in power system. In this paper, a closed-loop test platform which is based on real time digital simulator (RTDS) is established to test the performance of FACTS device controller. In this paper, static Var compensator (SVC) which is installed in a power plant is used for damping sub synchronous oscillation (SSO) excited by fixed series compensator installed in the transmission line which is to improve the power transfer capability. The control approach, operation mode and the install location of SVC are studied in this paper and the real controller performance has been verified by the proposed test platform. Beside, this platform can also used for the test of performance of other FACTS devices controller.
