摘要
研究了利用小波变换方法检测含风电场电网电能质量扰动的原理,并对谐波、电压波动及电磁暂态等电能质量扰动进行了MATLAB仿真.仿真结果表明,该方法能够实现对电能质量扰动快速又准确的检测,为研究含风电场电网中电能质量扰动的评估和治理提供了依据.
The principle of power quality detection of power system including wind farm with WT is analyzed in detail, and the Matlab simulation of power quality disturbances such as harmonics, voltage fluctuation and electromagnetic transient are carried out. Through the simulation analysis, the power quality disturbances can be detected quickly and accurately by the proposed method. Therefore, the basis is provided for the evaluation and control of the power quality disturbance brought by the power system including wind farm.
