Method for monitoring and counting power supply reliability of terminal of power grid

Abstract

The invention provides a method for monitoring and counting power supply reliability of the terminal of a power grid. The method is carried out through an electric energy meter arranged at the terminal of the low-voltage power grid. The electric energy meter comprises an electric energy metering unit, a main control unit, a human-machine interface unit, a storage unit, a real-time clock unit, a communication interface unit and a power module. The method includes the steps of 1, initialization of the electric energy meter; 2, power-on time recording; 3, power-down time recording; 4, power failure time counting; 5, power supply reliability counting. The method is simple, practical and reliable, the power supply reliability of the terminal of the low-voltage power grid can be effectively monitored and counted, the gap for monitoring and counting the power supply reliability of the terminal of the power grid in the prior art is filled in, and an effective information support is provided for a power supply department to improve the power supply quality of the terminal of the power grid.

Description

technical field [0001] The invention relates to the technical field of electric energy quality detection, in particular to a method for monitoring and counting the power supply reliability rate of a power grid terminal. Background technique [0002] With the development of society, people pay more and more attention to the power quality problem at the low-voltage terminal of power grid. The reliability rate of power supply is an important measure of power quality. The reliability rate of power supply will directly affect the safety of user equipment and reflect the technical level of power supply enterprises. Improving the reliability rate of power supply is not only the expectation of users, but also the goal of creating a first-class power supply enterprise. One of the main technical indicators that must be achieved. [0003] The monitoring and analysis of power supply reliability is a prerequisite for improving and governing the quality of the power grid. Only by timely ...

AI Technical Summary

Problems solved by technology

At present, most of the monitoring and statistics of the power supply reliability rate by the power supply department are based on an area or even a larger area, which is relatively extensive. Therefore, it is very necessary to develop a device capable of monitoring and counting the reliability rate of power supply at the end of the low-voltage power grid and to provide a method for monitoring and counting the reliability rate of power supply at the end of the low-voltage power grid
