摘　　要：为实现多类风电场站等值模型综合评价,搭建全拓扑详细模型作为基准模型,通过集电网络等值与风电机组聚合分别得到单机等值模型、馈线等值模型2个评价对象。提出基于改进层次分析的等值模型综合评价体系,包含多工况的时空层面评价指标。针对所提评价指标,在PSCAD/EMTDC环境中对3个模型展开仿真测试,给出2个等值模型的综合评价结果:在对仿真速度要求不高时,馈线等值模型评价综合值更高,具备多种问题分析能力,普适性更好。所提综合评价体系从仿真层面出发,实现了对风电场站等值模型包括稳态运行点、小干扰、暂态运行条件、集电网络空间体征、仿真速度多项指标的全方位评价。In order to realize the comprehensive evaluation of multiple equivalent model of wind farm,the detailed topology model is set up as the benchmark model,and the single-wind-turbine equivalent model and the feeder equivalent model are obtained respectively through the equivalent of collector lines and the aggregation of wind turbines,as two evaluation objects.A comprehensive evaluation system of equivalent model based on improved hierarchical analysis is proposed,which includes the spatio-temporal indexes of multiple working conditions.According to the proposed evaluation index,three models are simulated and tested in PSCAD/EMTDC environment,and the comprehensive evaluation results of the two equivalent models are given:when the demand for simulation speed is not high,the feeder equivalent model has higher evaluation comprehensive value,multiple problem analysis ability and better universality.Based on the simulation,the proposed comprehensive evaluation system realizes the comprehensive evaluation of the equivalent model of wind farm,including the steady-state operating point,small disturbance,transient operating condition,spatial signs of the collector lines and simulation speed.
