摘要: 具有低压穿越能力的风电机组接入系统后,整定计算时不能将风电等同于简单的负荷系统,以某110kV系统所接风电整定计算为例,分析了定值整定应考虑的因素,提出了风电场内部及其与大电网的联络线定值整定配合方法。

Abstract: After the wind farms with low voltage ride through (LVRT) capability are connected into power system, in the settings calculation of the farms, it is unable to consider the wind farms as a simple load system. Taking the settings calculation of a wind farm connected into 110kV system as example, the factors, which must be taken into account in settings calculation, were analyzed; and a settings matching up method, for inside of the wind farm and the tieline with large power grid, was proposed.
