Power supply reliability automatic calculation and analysis device and method for low-voltage distribution network

Abstract

The invention discloses a power supply reliability automatic calculation and analysis device and method for a low-voltage distribution network. An intelligent residual current action protector is used for monitoring and uploading data of trip shutting time, closing time, power losing time and power supply recovering time of low-voltage users in a real-time manner, reporting warning information to a server network and finally storing in a fundamental database of a reliability analysis system for the low-voltage distribution network of a server of a country bureau monitoring center, a monitoring terminal is used for inputting the data of the low-voltage users and power failure events of single-household or multi-household overhaul, temporariness and emergency repairing and storing in the fundamental database of the reliability analysis system of the low-voltage distribution network, and the server of the country bureau monitoring center is used for processing and analyzing input data and finally displaying on the monitoring terminal. The invention establishes a set of power supply reliability analysis system for the low-voltage distribution network with real-time automatic calculation of power supply reliability of the low-voltage distribution network, so that the problems of difficult and trivial mathematical statistics of the power supply reliability of the low-voltage distribution network can be solved, and simultaneously the accuracy of the power supply reliability of the low-voltage distribution network is improved.

Description

technical field [0001] The invention relates to a method and device for automatically calculating and analyzing the power supply reliability of a low-voltage distribution network. Background technique [0002] To accurately calculate the power supply reliability rate of low-voltage users, the key is to have accurate power outage time, number of power outages, and number of power outage households. Now these data need to be manually extracted from repair records, power outage operation tickets, work tickets, etc., and then counted. This is not only cumbersome, but also makes statistical data incomplete and reduces the accuracy of power supply reliability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-voltage distribution network power supply reliability automatic calculation and analysis device and method, establish a set of low-voltage distribution network power supply reliability analysis system with rea...
