摘　　要：风力发电场并网运行会降低电网的稳定性和电能质量。因此,在建立风力发电场仿真模型的基础上,通过仿真软件对不同运行方式下系统电压、频率的波形分析,探讨了电网中风力发电场的最大注入功率问题,给出了分析这一问题的简单的思路和方法,得出结论:系统节点电压和频率随风力发电场注入功率的变化而波动,且频率的波动更易超出系统稳定的约束界限;电力系统计算机辅助设计(PSCAD)仿真模型能较好地模拟网络各种动态过程,比应用MATLAB等仿真软件更接近于真实系统,适用于风力发电场具体问题的研究。The grid connected operation of wind farm will lower the stability and power supply quality ot power gna. Therefore, through wind farm modeling and the simulation-software-based waveform analysis of systematic voltage and frequency under different operational modes, the maximum injection power of wind farm in power grid is approached and a simple analytic method offered. It is concluded that systematic node voltage and frequency fluctuate with varied injection power of wind farm, and the frequency is more likely to fluctuate beyond systematic stability limits; the simulation model built by power system computer aided design （PSCAD） can simulate diversified dynamic processes of network better, approximates to the real system more than those built by MATLAB, etc, and is fit for the study on problems concerning wind farms.
