摘要
提出了恒速异步风电机组和静止同步补偿器的数学模型,使用Matlab中的动态仿真工具Simulink建立了静止同步补偿器的控制模型,以包含风电场的单机无穷大电力系统为例进行了仿真计算,验证了静止同步补偿器对风电场暂态电压稳定性的贡献。研究结果表明:风电场发生三相短路的大扰动故障时,静止同步补偿器能够有效帮助恒速异步风电机组在故障后恢复机端电压,从而改善风电场的暂态电压稳定性,确保风电机组连续运行。
The mathematical model of constant speed wind power generation set and that of static synchronous compensator （STATCOM） are proposed respectively, and by use of the dynamic simulation tool Simulink in Matlab software, a control model of STATCOM is built. The simulation of a single machine infinite bus system containing wind farm is conducted by which the contribution of STATCOM to transient voltage stability of wind farm is validated. Research result shows that when large disturbance such as three-phase short circuit fault occurs in wind farm, STATCOM is an effective means during the post-fault terminal voltage recovery of constant speed induction generator sets, thus the transient voltage stability of wind farm can be improved to ensure the continuous operation of wind power generation sets.
