Damping Controller

Supplementary subsynchronous damping controller (SSDC) is an effective countermeasure to damp the subsynchronous oscillation (SSO) caused by HVDC. On the basis of analyzing the mechanism of inducing SSO by HVDC, the principle of damping SSO by SSDC and SSDC design methods are expounded. A SSDC is designed for a practical power plant in China, and the correctness and validity of the SSDC control strategies are proved with time domain electromagnetic simulation results.
