Integrated system and method for relay protection health management

Abstract

The invention discloses an integrated system and an integrated method for relay protection health management. The system comprises a data collection unit used for collecting equipment information; a central processing unit used for receiving and processing the equipment information and judging whether the equipment has a fault or not according to a processing result; an alarm unit used for givingan alarm when the central processing unit detects that the equipment information is abnormal; an execution unit used for removing the faulted equipment from the power system when the central processing unit detects that the equipment information is abnormal; and a power supply module used for supplying power to each electric facility in the system. The system is more accurate in detection, and canaccurately distinguish fault reasons. Therefore, the waste of manpower and material resources can be avoided. Meanwhile, the development trend and fault characteristics according to the fault recordsof all equipment can be determined. Therefore, the preventive maintenance is facilitated. In addition, the system can position the faulted equipment, so that the rapid positioning and maintenance ofthe equipment is facilitated for workers.

Description

Technical field [0001] The invention relates to the field of relay protection, in particular to an integrated system and method for relay protection health management. Background technique [0002] Relay protection is an important measure to detect faults or abnormal situations that occur in the power system, so as to issue an alarm signal, or to isolate and remove the fault part directly. Relay protection is an anti-accident automation measure that studies power system failures and endangering safe operation in order to explore its countermeasures. Because in its development process, relays with contacts were mainly used to protect the power system and its components (generation Machines, transformers, power transmission lines, etc.) to prevent damage, so it is also called relay protection. The basic task of relay protection is: when the power system fails or abnormal working conditions, in the shortest time and smallest area possible, automatically remove the faulty equipment ...

AI Technical Summary

Problems solved by technology

[0006] (1) When the relay protection system detects the fault information of the equipment in the power system, it will not only alarm when the equipment fails, but also when the protection device itself fails, and the secondary circuit connecting the primary equipment and the protection device fails 1. When the communication system fails, it will alarm, making the cause of the failure unclear and affecting the reliability of relay protection;

[0007] (2) In different periods of equipment use, the probability of failure is also different. The existing relay protection health management integrated system cannot determine its development trend according to the records of equipment failure, which is not conducive to preventive maintenance. It is not conducive to maintaining the stability of the power system;

[0008] (3) There are many devices working at the same time in the power system. When one of the devices fails, it is difficult to locate the faulty device, which is not conducive to the rapid positioning and maintenance of the staff and affects the use of the device
