Modal Research on the Low-Frequency Oscillation of AC/DC System with DFIG-Based Wind Farms

Abstract:

Low-frequency oscillation characteristics of AC / DC system with DFIG-based wind farms were studied. Detailed mathematical pure AC and AC / DC system model were established by considering the effects of doubly-fed wind turbine model and DC transmission dynamic model to do small signal stability analysis. The computed results of small signal stability of DFIG-based wind farms integrating pure AC CEPRI36 nodes system or with DC transmission that operated in four connection modes including bipolar neutral grounding at both ends mode, monopole ground return mode, monopole metallic return mode , monopole and two parallel conductor mode with earth return were investigated by using modal analysis method. Then, the characteristics of local oscillation modes and inter-area oscillation modes were respectively analyzed under the two operation modes of the wind farm participating active power dispatching and reactive power dispatching and consequently some new conclusions were drawn.
