A New Adaptive Load Rate Approach of Transformer in Power Grid Monitoring System

doi:10.11985/2017.06.005

Abstract

Abstract:

Under centralized monitoring model for power grid, the traditional calculation method for monitoring transformer loading rate is influenced by measurement value sampling of medium voltage side and low voltage side circuit breakers. Based on network topology analysis in regulation technical support system, switch state parameter and transformer state parameter is introduced. A new adaptive loading rate approach is proposed and simulation model verifies the effect of this model. Through this simulation model, the adaptive loading rate algorithm can correctly get the load rate of transformer, which is not influenced by measurement value sampling of medium voltage side and low voltage side circuit breakers. The method is important to scientific regulation and careful monitoring.

Key words: Power grid monitoring, loading rate, adaptive
