Relay protection constant value monitoring method and device, relay protection device and storage medium

Abstract

The invention relates to a relay protection constant value monitoring method and device, a relay protection device and a storage medium. The method comprises the steps of obtaining the target binary data, wherein the target binary data comprises the binary data corresponding to each piece of constant value information; splitting the target binary data to obtain each piece of sub-data, and carrying out XOR operation on each piece of sub-data to obtain a monitoring feature code; and determining a constant value monitoring result according to a comparison result of the monitoring feature code and a preset feature code. The method has the advantages of being small in calculation amount and simple in step, the constant value monitoring can be completed through a relay device, and therefore the monitoring cost and the upgrading and rebuilding difficulty can be reduced. Meanwhile, in the monitoring process of the relay protection device, a safety computing power margin can be reserved, so that the safety of a power grid can be improved, the scheme of the invention can be applied to most relay protection devices, and the applicability is enhanced.

Description

technical field [0001] The present application relates to the technical field of grid equipment operation and maintenance, and in particular to a relay protection fixed value monitoring method, device, relay protection equipment and storage medium. Background technique [0002] With the rapid development of the power system, the scale of the power grid is growing day by day, and the connection between power and society is getting closer. Therefore, it is particularly important to ensure the safe operation of the power system. Among them, whether the setting value of the relay protection equipment is correct or not directly affects the correctness of the protection action of the equipment, and is closely related to the reliability of power supply. Therefore, in the operation and maintenance process of power grid equipment, it is often necessary to monitor the setting value information of relay protection equipment in real time to ensure the operating conditions of relay prote...

Problems solved by technology

[0003] At present, the verification method of relay protection setting value is still mainly manual checking, that is, after the setting value is printed on paper or summoned to the local background, it will be checked item by item. The checking process is time-consuming and laborious, and the scale of relay protection equipment will increase. It also greatly increases the pressure of operation and maintenance

In addition, there are many equipment setting items, and manual checking item by item is prone to mistakes and omissions, which is not conducive to the safe operation of relay protection equipment

[0004] In order to improve the problems of heavy operation and maintenance pressure, decreased safety and low monitoring efficiency caused by manual checks, the traditional technology realizes the fixed value monitoring by combining the fixed value printing communication interface of the relay protection equipment with the newly added auxiliary device; Or call the fixed value to the background system and monitor it through auxiliary software

However, the traditional method requires additional devices to realize the fixed value monitoring, which has the problem of high cost
