Description
Summary:Wide-area measurement system (WAMS) provides a platform for more efficient control, and some discontinuous types of wide-area control projects have been reported in commission in the recent years. In this paper, a continuous type of wide-area damping control system (WADCS) is introduced, which is used to suppress the inter-area oscillations in a complicated real power grid by modulating multiple HVDC links. The background of WADCS project is described. The design fundamentals and the implementation framework of WADCS are briefly summarized. The details of the field experiment items and some important test results are presented, which show that some new problems in wide-are control are successfully solved and WADCS can operate correctly in different conditions.
