Application Case: Mitigation of SSO in Type 3 Wind Power Systems

This chapter presents an application case of practical oscillation damping control techniques implemented on a real-world wind power system facing subsynchronous oscillation (SSO). First, the real-world SSO events in the Guyuan wind power systems are discussed. Then, the generator and grid side damping controls are designed, developed, and tested through controller hardware in the loop simulations. The generator- and grid-side subsynchronous damping controls have been put into service in the actual wind power system facing the SSO.
