Problems solved by technology

[0006] On the one hand, due to the fact that some switching stations (switching stations are power facilities that supply high-voltage power to several surrounding power units respectively, are located at the next level of the substation in the power system, and are a type of equipment in the distribution network system. Including switch, protection, terminal equipment, etc.) The switch is not operated for a long time, causing the mechanism to be stuck, the electric mechanism is rusted, and the remote control cannot be operated normally, which hinders the normal control of the dispatcher on the distribution network

Embodiment Construction

[0028] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0029] Such as figure 1 As shown, a method for testing the planned state of a distribution network switch includes the following steps:

[0030] A: Select the distribution network switch and sort it:

[0031] The planned state test operation of the distribution network switch ensures the accuracy of the distribution network switch action, but large-scale switch tests will affect the operation mode of the distribution network and the power consumption of users, so the state test of the distribution network switch is planned , selective, focused.

[0032] a01: Collection of distribution network switches: Incorporate the switches in the online moni...

Abstract

The invention discloses a method for testing the planning state of a distribution network switch. State testing operation is carried out on the distribution network switch in a periodic, planning and selective mode, and due to filtering and sorting of the distribution network switch, the efficiency and effect of testing the planning state of the distributing network switch can be improved, and under the multiple check and analysis, accuracy of the switch motion is ensured, and the operating mode of a distributing network and electricity use of a user cannot be affected by the switch test.

Description

technical field [0001] The invention relates to a state monitoring module in a power distribution automation system, in particular to a planned state testing method for a distribution network switch. Background technique [0002] The distribution network is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensation capacitors, and some ancillary facilities. The network complexity, large amount of equipment, and frequent changes are major characteristics of the distribution network. Many problems have been caused to the application functions related to distribution network analysis. The distribution network is an important part of the power system and plays an important role in distributing electric energy in the power network. Its safety and reliability will directly affect the development of the national economy and people's living standards. The network situation of the distribution network is complex and the ope...
