【摘要】 为了更方便、快捷、准确地进行中长期负荷预测,开发了基于Windows的电力系统中长期负荷预测软件。软件采用面向对象程序设计方法,使系统易扩充、易维护。该软件除具有一般负荷预测软件所具有的计算快速、模型库丰富等特点之外,还有原始数据输入简单方便、模型库扩充简易、具备饱和负荷预测以及考虑了与其它常用软件的接口等独特的地方。以华东某地区的供电量历史数据为例,选择了5种不同模型进行预测,并对结果进行了分析和比较,最后还对该地区进行了“s”型饱和负荷预测。分析表明该软件使用方便,预测精度满足电力负荷预测的精度要求,具有一定的实用性。更多还原

【Abstract】 It is a power system mid-long term load forecasting software based on windows for load forecasting conveniently and precisely,which is easy to make expansion and maintenance because of using OOP.The software not only has high calculation speed and various model library like others,but also has data input conveniently,model library expand easily and interface for other power software.Taking the historical data of electrical energy demand of a certain region of The East China for example,five different models are used for load forecasting and comparing with their forecasting results,and also forecasting the saturated load using s-type increasing curve.Analysis shows that the software has using conveniently,proper model library a high accuracy of forecasting results,so this software can meet the need of load forecasting precision in actual work.更多还原
