Constant value checking method based on mobile application

Abstract

The invention discloses a constant value checking method based on a mobile application. The constant value checking method based on a mobile application includes the following steps: 1) compiling transformer station equipment operation constant value orders and saving the transformer station equipment operation constant value orders in a constant value checking management system, and establishingorder number archives of the regional power grid constant value orders; 2) starting a constant value order flow management work order and transmitting the constant value order to the transformer station field and the work area field at the same time, wherein the field operation personnel saves the constant value orders and determines the constant value work order; 3) starting a secondary mode workorder while the field operation personnel executes transformer station equipment constant value input or adjustment and determines the secondary mode work order after the work is completed; and 4) starting constant value checking, completing constant value order number checking and constant value content checking, and saving the transformer station equipment information acquired by the field operation personnel. The constant value checking method based on a mobile application utilizes a mobile interaction platform to establish a constant value checking management system, automatically checksthrough the constant value order QR-code or bar code to realize automatic closed loop management of inquiry, flowing, checking and archiving of the constant value orders, and can replace a traditionalartificial constant value checking method.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a fixed value checking method based on mobile applications. Background technique [0002] As a line of defense to ensure the safety of the power grid, the reliable operation of relay protection and automatic safety devices is of great significance to the safety and stability of the power system. The refusal and malfunction of the device is one of the important factors that trigger or accelerate system disturbances. Among them, the correctness of the setting value of the relay protection device directly affects the correctness of the action of the protection device, and its importance to the safe and reliable operation of the power grid is self-evident. In recent years, there have been many accidents across the country caused by problems with the fixed value of the device or the incompatibility of the position of the hard pressure plate of the device. Coupled with...

AI Technical Summary

Problems solved by technology

[0006] ①The combing process of the fixed value order number is relatively complicated

Before each fixed value check is carried out, the relay protection room will arrange special personnel to sort out and summarize the fixed value single numbers implemented by the current power grid, but this process is complicated and prone to errors and omissions

[0007] ②Fixed value verification has tight working hours and heavy tasks

The staff of each operation and maintenance station need to complete the verification of the fixed value of all protective equipment in the sub-stations under the jurisdiction of the operation and maintenance station. The workload is relatively large, which increases the burden on the already busy daily work, and is also prone to omissions

[0008] ③Lack of management and control in the process of verification of fixed value, and weak supporting materials

The verification results of the fixed value are fed back to the control center by the transportation inspection department in writing, and then the control center summarizes the feedback to the company leaders or the provincial survey. However, the verification process lacks supervision, and the relevant materials of the verification work are difficult to show

[0009] ④The results of spot checks cannot represent the implementation of the fixed value of the entire network

Due to the limited personnel, the relay protection room urges the operation and maintenance personnel to complete the relevant work by spot-checking the implementation of the fixed value of some substations, but the spot-check results are not the real situation of the whole network after all.
