摘　　要：以PSS/E和风机软件包为平台,建立了基于滑差可调绕线式异步风电机组的恒速恒频风电场模型,并以CIGREB4-39风电场并网系统标准模型为例,研究了不同种风速扰动下的风电场动态特性,分析了对于不同容量、不同并网点风电场在不同种故障点扰动下保持稳定运行的能力。研究表明,扰动风速增量过大时,风电场振荡加剧;在一定容量范围内,大容量风电场表现出更强的抗扰动能力;同步发电机的调节作用对近区风电场稳定运行有明显改善的效果。In this paper, the PSS/E and WIND Package are taken as a simulation platform. Based on the slip adjustable wound rotor induction generator, the clearly Constant Speed Constant Frequency wind farm model is established, and CIGRE B4-39, a standard grid model including grid-connected wind farm is taken as an example. Dynamic characteristic and interaction between wind farm and grid with different capacity of wind farm and different grid-connected point in various fault position is compared and analyzed, as well as at different kinds of wind speed disturbance. Research result indicates that, if the wind speed disturbance is too large, oscillation of the wind farm will aggravate, within a certain capacity, high-capacity wind farm shows stronger anti-disturbance ability; on account of the synchronous generator regulation, the stability of the wind farm nearby is improved obviously.
