Distribution Network Power Flow Calculation Based on Load Monitoring System

The load monitoring system can collect the real-time data information about the active and reactive power load on the 10 kV feeder,whereupon a mathematical modeling method based on load monitoring system is proposed for distribution network load in this paper. After all network components are modeled,the information on voltage,phase angle and the total active and reactive loss of all the nodes of the distribution network can be obtained by forward and backward substitution for calculating power flow to provide reference for operation and management decisionmaking. Through calculation analysis on power flow of actual operating line in Songjiang Grid,the general laws about how the different network parameters affect the power grid operation indicators are obtained,which further validates the important role and potential applications of load monitoring systems in distribution network operation analysis,indicators evaluation and so on.
