A secondary equipment online monitoring and analysis system and method

Abstract

The invention discloses a system and method for online monitoring and analysis of secondary equipment. The online monitoring and analysis system for secondary equipment is composed of hardware equipment such as a communication gateway and a dispatching data network. Devices, backup self-switching devices and low-cycle load shedding devices and other secondary equipment communicate, and at the same time, the communication gateway in zone I transmits real-time relay protection device information, backup self-switching devices and low-cycle load shedding device information to the dispatcher; line monitoring The analysis and analysis system realizes real-time monitoring of the operating status of the device through information filtering, information classification and information query; through online fault analysis and comprehensive multi-source information for fault diagnosis, and finally forms a fault report, providing reliable criteria and rich information for comprehensive intelligent alarms Fault information; ensure the safety and reliability of remote control; provide reliable statistical data for operation analysis and evaluation by performing real-time automatic statistics on the operating status and operating conditions of secondary equipment.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to an on-line monitoring and analysis system and method for secondary equipment. Background technique [0002] The Baoji area has a large power supply radius and a wide range of power supply. In the past, when the system failed, it was mostly observed and recorded manually by the on-duty personnel of the substation and then reported by telephone. The accuracy and speed were not satisfactory. In order to analyze and judge accidents, relay protection personnel urgently need on-site fault recording reports and microcomputer protection print reports. In order to obtain these information, relay protection personnel have to drive a long distance to retrieve the recording images, which is not conducive to accident handling. To a large extent, the speed of troubleshooting is restricted, and the operation and maintenance costs are high. [0003] The rapid, accura...

Problems solved by technology

[0004] At present, domestic substations only realize the direct transmission of the wave recording data of the fault recorder to the dispatching end through the dispatching data network, and the important alarm and trip information of the protection device are transmitted to the monitoring end through the telecontrol system, and the real-time collection of secondary equipment has not been realized. The transmission of analog data has not realized holographic transmission and online fault analysis, so it is necessary to research and develop a comprehensive secondary equipment online monitoring and analysis system and method
