摘要
为考虑系统运行方式的随机不确定性,采用概率方法研究含风电场的电力系统的小干扰稳定性。在双馈风电机组转子侧变频器有功控制环加装电力系统稳定器,以改善风电并网系统小干扰概率稳定性。通过在五机两区域系统中进行仿真,比较了不同输入信号在多运行方式下的阻尼特性。仿真结果表明,双馈风电机组的转差和终端电压是最为合适的输入信号,二者的阻尼效果相同。
In order to consider the stochastic uncertainty of system operating conditions,a probabilistic method was adopted to study the small-signal stability of power system with the integration of wind farm. A power system stabilizer（PSS）was installed in the active power control loop of rotor-side converter of doubly-fed induction generator（DFIG）for improving the probabilistic small-signal stability of power system connected with wind farm. By simulation on a fivemachine two-area system,the damping characteristics of different input signals were compared under multi-operatingconditions. Simulation results show that the slip and terminal voltage of DFIG are the most appropriate input signals,and their damping effects are identical.
