A low-voltage troubleshooting method for low-voltage users based on normal distribution statistics

Abstract

The invention relates to a low-voltage screening method for low-voltage users based on normal distribution statistics, and relates to a low-voltage screening method. At present, low-voltage users are distributed at the end of the distribution network, with a large number, and the means of voltage monitoring for low-voltage users are scarce. When installing voltage monitors, there are also problems of large number of monitoring points and huge costs. The present invention comprises the following steps: low-voltage users comprehensive investigation step; voltage call test for some users under the selected station area; analysis of call test results, and low voltage low voltage users listed as objects of low voltage control; judging whether All the regions are selected, if the selection is not completed, then return to the step of selecting the regions; if the selection is completed, then end. The technical solution has high efficiency in troubleshooting, and can deal with low-voltage users in a timely manner to obtain corresponding solutions. The low-voltage analysis and troubleshooting of low-voltage users is fast, and timely treatment can improve the quality of power supply, reduce the time of power outages, and ensure the power consumption of people's production and life.

Description

technical field [0001] The invention relates to a low-voltage screening method, in particular to a low-voltage screening method for low-voltage users based on normal distribution statistics. Background technique [0002] Low-voltage users are distributed at the end of the distribution network, with a large number of low-voltage users, and lack of voltage monitoring means. At present, the more effective low-voltage monitoring means is to install voltage monitors, but there are also a large number of monitoring points and huge costs, and the current voltage quality is generally poor. In the case of high voltage, the effect is little. Another way is to monitor the low-voltage outgoing line voltage of the low-voltage side of the distribution transformer according to the public transformer monitoring terminal. Although there is a certain reference value, it is still impossible to monitor the low-voltage user voltage at the end of the low-voltage loop with a too long power supply r...

[0002]The low-voltage users are distributed at the end of the distribution network, and there are a large number of low-voltage users. The voltage monitoring means for low-voltage users are scarce. Currently, the more effective low-voltage monitoring means is to install voltage monitors, but there are also The number of monitoring points is large, the cost is huge, and the current voltage quality is generally high, and the effect is very little. Another way is to monitor the low-voltage outlet voltage of the low-voltage side of the distribution transformer according to the public transformer monitoring terminal. Although it has certain reference significance, However, it is still impossible to monitor the low-voltage user voltage at the end of the low-voltage circuit with a too long power supply radius
