摘　　要：风电机组短路电流计算是新型电力系统分析与控制的重要前提,目前有关全功率型风电机组的短路电流研究多集中于故障初期的计算,鲜少涉及故障穿越全过程。文章基于某实际全功率型风电机组的厂家封装模型,详细分析了其故障穿越全过程短路电流的动态行为;并基于对机组控制策略的完整建模,分别推导了故障发生时的瞬态、故障持续期间的暂稳态、故障清除后的瞬态和故障清除后的恢复等四个阶段的短路电流暂态行为解析式,提出了故障穿越全过程短路电流的解析计算方法。通过故障穿越全过程的机组短路电流解析计算结果和厂家黑盒封装模型短路电流测试结果的一致性对比,验证了文章提出方法的有效性。Accurate calculation of short-circuit current throughout the fault ride-through process of wind turbines is a critical prerequisite for the analysis and control of modern power systems.Current studies on the short-circuit current of full-converter wind turbines primarily focus on the initial fault stage,with limited attention given to the entire fault ridethrough process.This paper presents a comprehensive analysis of the dynamic behavior of short-circuit current across the entire fault ride-through process,based on the manufacturer-packaged model of a practical full-converter wind turbine.A complete model of the turbine's control strategy is constructed to derive analytical expressions for the transient behavior across four key stages:fault occurrence transient,steady-state during fault duration,post-fault transient,and post-fault recovery.An analytical method for calculating short-circuit current throughout the fault ride-through process is proposed.The validity of the proposed method is demonstrated by comparing the analytical calculation results with short-circuit current test results obtained from the manufacturer's black-box packaged model.
