一种考虑了负荷特性的企业电网潮流算法

大型企业电网的负荷特性主要表现为感应电动机群特性,为了改进现在常用的电力系统潮流算法中用恒功率模型来表征节点负荷,不能满足工程精度要求的问题,提出了在对企业电网负荷节点电动机群进行等效变换后,引入负荷特性的潮流计算的思路,在此基础上进行了理论推导,并经过现场实测数据,进行了仿真。仿真结果表明,负荷特性的潮流计算方法符合企业工程精度要求,可以达到提升业电网潮流计算结果在精确度、实用度等方面的要求,具有一定的理论和工程意义。

A Method Considered Characteristic of Load of Calculation of Power Flow of Radial Industry of Network

Because of the special hiberarchy characteristic of industry distribution network,the equivalent model of induction motors should be considered correctly.In the usual calculation of power flow of industry distribution network,load of distribution network only be regarded as invariableness power model,which make the result of calcution be incapable of the require of engineering precision volatage stabilization etc.In this paper,the authors try to give us a thoughtway that the trait combinatios of induction motors should be considered in calculation of industry distribution network.The result of this paper gives a reference of the calculation of power flow of distribution network,which will make the result better than the former.
