Research on Condition Monitoring Technology of Modular Reactive Power Compensation Control System

In this paper, an intelligent modular RPC (Reactive power compensation) system state monitoring system is established. According to the running state data of the modular RPC control system collected by the distribution transformer terminal information collection system; A comprehensive state evaluation model of modular RPC control system based on Bayesian network is established. In the evaluation, the model deals with the problems of over-compensation and under-compensation, frequent switching and control sensitivity of modular RPC control system. Based on Java platform, the state monitoring software of modular RPC control system is designed and developed. It is found that the error between the monitoring system and the standard power quality meter is less than 1%, so it can be considered that the three-phase voltage data monitored by the three-phase basic electrical parameter monitoring module is accurate. It can realize comprehensive on-line monitoring of the running state of modular RPC control system.
