DISTRIBUTED ELECTRIC POWER QUALITY MONITORING SYSTEM

The present invention provides a distributed electric power quality monitoring system, comprising: a quality monitoring module, which is set at various nodes in the power grid, used for collecting electric power quality parameters at each node of the power grid; a communication network module, which is connected to the quality monitoring module, used for transmitting the collected electric power quality parameters; a central monitoring module, which is connected to the communication network module, used for receiving, processing, and storing data transmitted from the monitoring equipment; a processing analysis module, which is connected to the central monitoring module, used for conducting power quality analysis on the processed data; an alarm feedback module, which is connected to the processing analysis module, used for timely issuing alarm signals and providing problem descriptions and suggestions based on the analysis results. The present invention adopts a distributed remote monitoring method with automatic detection and analysis, eliminating the need for on-site personnel detection. At the same time, it predicts each node by obtaining the central node, reducing the data transmission volume per unit time and avoiding data transmission congestion.
