Abstract

The load monitoring system can collect real-time information on active and reactive power of the 10 kV feeder, based on which a mathematical modeling method based on load monitoring system is submitted in this paper. All network components are built a model, 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 decision-making. Through calculation analysis on power flow of actual operating line in Songjiang Grid, the general laws of the different network parameters on the impact of power grid operation indicators are obtained, the important role and potential applications of load monitoring systems in distribution network operation analysis, indicators and evaluation are further validated.
