Online state monitoring self-diagnosis system of box-type substation

Abstract

The invention discloses an on-line state monitoring self-diagnosis system of a box-type substation, belongs to the technical field of substation monitoring, and provides the following scheme: the on-line state monitoring self-diagnosis system of the box-type substation comprises a state monitoring module, a self-diagnosis module and a self-diagnosis module, the monitoring module is used for monitoring a voltage signal, a current signal, an overload signal, a temperature and humidity signal, an electric leakage signal, a switch I / O signal and an environment signal of a line in the box-type substation in real time; the PLC is used for carrying out analysis processing according to the state parameter information of the box-type substation and comparing the state parameter information with a corresponding threshold value so as to diagnose whether the box-type substation runs abnormally or not in real time; the communication module uploads the state parameter information of the box-type transformer substation to the transformer substation comprehensive management and control platform, and the transformer substation comprehensive management and control platform sends out alarm information of the box-type transformer substation which operates abnormally; and the transformer substation comprehensive management and control platform displays basic information, working condition states and fault maintenance states of the box-type transformer substation. According to the technical scheme, safe and normal operation of the power transmission and transformation equipment in the box-type substation is ensured.

Description

technical field [0001] The invention relates to the technical field of substation monitoring, in particular to an online state monitoring self-diagnosis system of a box-type substation. Background technique [0002] With the rapid development of social economy, electric power has become one of the key driving forces for social and economic development, so the importance of power transmission and transformation equipment is self-evident. How to diagnose whether the power transmission and transformation equipment in the substation is in normal operation, how to effectively use the monitoring data provided by the online monitoring unit to analyze and diagnose the status of the power transmission and transformation equipment, and determine whether the substation and the equipment in the station are in normal operation are all things we need to discuss and study of. [0003] In the prior art, the box-type substation status online monitoring system uses voltage transformers, curr...

Problems solved by technology

[0004] However, the monitoring parameters of the system are single and one-sided, lack of monitoring of the substation environment and state, the measurement range of the verification is also narrow, and lack of comprehensive parameter collection for the substation; at the same time, the coordination of multi-parameter sensors is not considered.
