Problems solved by technology
There are few monitoring equipment for the operation status of the distribution network, and the lack of information transmission channels, so the amount of information collected is small, which leads to a low degree of automation in accident handling, long processing time, and slow recovery of power supply after the accident.
[0007] In recent years, power grid accidents have occurred in some areas, leading to power outages for important users. In addition to some human factors, the weak grid structure and low reliability are the main reasons; the low degree of automation and poor management are also important reasons.

The invention provides an information collector of a distribution network switching station. The information collector is used for completing access and uploading of a large amount of information of the switching station. Different kinds of collected information are mainly obtained through different collectors. In order to achieve the aim, the information collector of the distribution network switching station is used in cooperation with an existing monitoring center and comprises a collecting assembly and a communication assembly. The collecting assembly comprises a telecommand unit, a telemetering unit and a telecontrol unit. The communication assembly comprises a data forwarding module and a plurality of expansion interfaces installed in the data forwarding module. By means of the arrangement, the information collector enables all the information to be collected and uploaded to the data monitoring center in a unified mode. According to the information collector, the collecting assembly and the communication assembly are both arranged in a plug-in mode and can be installed in an embedded mode, plug-ins are only required to be additionally arranged under the condition that the information amount is required to be increased, and the installation collector is flexible and convenient to install.
Description
technical field [0001] The invention relates to power grid information collection equipment, in particular to an information collector for a distribution network opening and closing station. Background technique [0002] With the development of the national economy and the improvement of people's living standards, users have higher and higher requirements for power quality. The evaluation of user power quality mainly includes the following indicators: first, voltage quality, which includes three requirements of voltage deviation, voltage fluctuation and voltage flicker; second, frequency; third, power supply reliability, which is the distribution network There are as many as 11 evaluation indicators for the measurement of the user's continuous power supply capability, the main one is the annual average power supply reliability rate, that is, the percentage of the user's annual average power supply time; the fourth is the harmonic content, which should not be higher than the ...
