摘要
为研究电网扰动对风力发电系统稳定性的影响,采用电磁暂态仿真软件PSCAD/EMTDC,建立风力发电系统模型,通过对风力发电的轴-机-网系统进行时域仿真,研究不同的故障清除时间、不同的故障类型对风电机组电磁转矩的影响。提出故障的严重程度越高电磁转矩的峰值越大;另外在遭受故障后,系统存在着最佳清除故障时间区域以及临界故障清除时间点。
To study on the effect of the disturbance on wind power system stability, this paper established the wind power system model by electromagnetic transient simulation software PSCAD /EMTDC. It researches on the effect of the different fault clearing time and different fault types on the electromagnetic torque of wind power by the time domain simulation of wind power-machine-net system.It presents that the higher severity of the fault the greater peak value of electromagnetic torque. In addition,there is a best time region and the critical time point to eliminate fault for the system.
