Abstract

In order to control the fault state of the distribution network, a power distribution network fault risk early warning system is developed. This system divides the distribution network fault into three levels failures, equipment level failure, feeder level failure, and system level failure. By calculating the risk value, it sends an early warning message to a distribution operator when the risk value exceeds the limit value. It gets real-time operational data from distribution automation system via information bus, and gets equipment parameters from production management system via database. It uses equipment importance and equipment failure probability to calculate the equipment failure risk value. And then, it calculates the risk value for feeder level and system level. When the risk value exceeds a predetermined threshold, it starts alarm processing automatically and send warning message to the distribution operator. The results of application of the electric power company show that the system can detect faults in time and improve the reliability of power supply
