摘要
目前 ,我国对配电故障只能根据专业人员的经验 ,而不是科学数据来描述 ,不能及时准确地预测。为此 ,综合运用了数据仓库技术、统计学等多种手段 ,分析配电故障数据与气象因素、电网负荷和温度之间的关系 ,正确认识配电故障发生的规律 ,并选择合适的数据挖掘算法 ,建立有效的数学模型 ,根据气象因素 ,准确地预测配电故障发生和电网负荷的关系 。
Now in our country, it is according to professional's experience, not using scientificdata, to describe the occurrence of hitch.By the data warehouse,datamine and statistics techniques, we analyzed the relation between data of switch hitch and weather factor,electrical net's load and temperature, then got the rule of switch hitch, and selected a right datamine arithmetic to build an effective mathematic model. Basing on the mathematic model, it can forecast the occurrence of hitches and the load of electrical net according to the weather factor. The power supply bureau gets upper economic benefits.
