摘要
Abstract
Inverse time overcurrent is applied in low voltage power grid gradually .But the undetermined parameter setting is complex .The model of inverse time characteristic curve is elaborated .Considering the defects exsisting in the optimization model , and based on the exsisting model , a new model for calculation is proposed through the weight coefficient .The IEEE calculation is used to prove the model is useful in reducing the actuation time of the overall pro-tection, the protection time of the key circuit , increasing the protection time of common circuit and the reliability of the system .In the case of curve crossing , a simple approach to help computing and programming for further study is proposed at last .关键词
