Calculation And Analysis Of The Closed Loop Current Of Hebi Distribution Network And Its Decision System Study

The closed loop operation not only improve the flexibility but also the reliability of the network,It has high practical value to analyze the operation.Main content and conclusion of this thesis are as below.A typical closed loop operation of Hebi Distribution Network is set up for analysis. The maxium,the minimum and the approximate of closed loop current is get by setting five feeder models.A mathmatical model is established to analysize the steady-state loop current and the transient surge current. By comparing the simulated and theoretical results,it is proved that the method for the calculation of closed loop current is suitable.This paper also designed and developed a closing loop calculation software based on the above theory which is very easy and convenience.Finaly,this paper studyed on the whole framework of the decision system of the closed loop current.
