摘　　要：大规模风电场接入电网对电力系统分析计算提出了新的要求,风电场的等值简化对电流系统潮流计算、继电保护整定尤为重要。使用加权容量法对风电场进行等值简化,对不同类型的电网故障进行仿真,同时计及不同的风速环境,通过对比风电场等值机与风电场详细模型的输出变化,验证了风电场等值在电力系统分析计算中应用的可靠性。Large amount of wind power integrated into the power system requires new method in power system analysis. The equivalent simplification of wind farm is very important in power flow calculation and relay protection setting. Weighted capacity method is used in this paper. Different wind speed and fault types are considered. Calculation results are studied under detailed model and simplified model. Reliability of equivalent simplification method is verified in this paper.
