| 摘 要： | 针对大型特种钢铁企业所产生的冲击负荷影响地区负荷曲线的问题,介绍了一种利用维纳滤波对冲击负荷进行预处理的方法。对负荷曲线进行了频谱分析,得出维纳滤波具有过滤冲击负荷、消除毛刺使预测曲线光滑易于人工调整的优点。根据用维纳滤波在江苏苏州电网短期负荷预测中的实践,经过维纳滤波后的负荷曲线光滑平顺,可以提高预测算法的准确率。

| Abstract: | According to the problem that the impact load generated by large steel industries affects the area load curves,the paper introduces a method to pre-process the impact load using wiener filtering.Spectrum analysis to load curves shows that the wiener filtering has the merits of filtering impact load,removing burrs and smoothing forecast curves.The practical use of wiener filtering in the short term load forecasting of Suzhou grid shows that the load curves are smooth after wiener filtering.So the method can improve the accuracy of forecasting. |
