doi:10.11930/j.issn.1004-9649.2014.8.38.6

Abstract

Abstract: Performances of SVC controllers have critical impacts on voltage quality and operation stability of local grid integrated with large-scale wind power. A digital real-time model is built for power grid connected with wind farms and TCR based SVCs by real-time digital simulator(RTDS), which constitutes a closed-loop test system, and can carry out the performance tests on actual SVC controllers. The results show that this kind of closed-loop test system is capable of testing SVC controllers’ dynamic characteristics more comprehensively. And it is found that, for manufacturers, some functions of SVCs, such as signal measurement, regulator model design, coordination of the auxiliary controls and its switching modes still need to be improved and refined.

Key words: wind farm, static var compensator (SVC), coordination control of power sources and grids, real time digital simulation (RTDS), thyristor controlled reactor, performance test
