【 摘 要 】

In order to solve the problem in the prediction of low voltage problem in distribution network, a method of estimating low voltage problem is proposed from two aspects: network simplification and load simplification. In the basis of the difference construction of the backbone and branch line, a backbone-branch network simplified model is proposed, and also the large input parameters problem is solved through the parameter estimation. In the basis of the division of the trunk that a branch load model is structured to realize a rapid distribution of the load. And finally, by using the voltage droptheoretical, a simple and practical low voltage loss quick check is formed to make it easy for grassroots staffs to use.
