Transformer substation tripping and closing loop monitoring and early warning system and method

Abstract

The invention discloses a transformer substation tripping and closing loop monitoring and early warning system and method. The transformer substation tripping and closing loop monitoring and early warning system comprises a sensor module, a data conversion device, an acquisition unit and a management unit, the sensor module is used for collecting tripping and closing loop current, direct-current power supply loop current and temperature and humidity data and converging the data to the management unit step by step through the data conversion device and the collection unit, and the management unit is used for executing monitoring and early warning. Sensor modules are installed in tripping and closing loops and power supply loops of all intervals of a transformer substation to collect tripping and closing loop monitoring currents and power supply loop monitoring currents. The data conversion device converts the signals into SV signals and GOOSE signals and transmits the SV signals and theGOOSE signals to the acquisition unit. According to the transformer substation tripping and closing loop monitoring and early warning system and method, real-time monitoring, fault warning and faultpositioning of the transformer substation tripping and closing loop can be achieved, and the operation reliability of the transformer substation is improved.

Description

technical field [0001] The invention relates to the technical field of detection of tripping and closing circuits of intelligent substations, in particular to a monitoring and early warning system and method for tripping and closing circuits of substations. Background technique [0002] The safety and reliability of tripping and closing circuits in substations is of great significance to the normal operation of circuit breakers. However, the existing substation secondary system lacks a monitoring and early warning device for the tripping and closing circuit, lacks real-time monitoring means for the state of the tripping and closing circuit, and has no effective fault alarm and abnormal location method when the circuit is abnormal. Therefore, in order to improve the monitoring and early warning of the tripping and closing circuit, it is of great significance to study the fault alarm and abnormal location method of the tripping and closing circuit for the safe and reliable ope...
