Implementation method of province, city and county integrated relay protection setting calculation overall-process management system

Abstract

The invention provides an implementation method of a province, city and county integrated relay protection setting calculation overall-process management system. The system comprises an engineering management module (1), an electrical equipment parameter management module (2), a drawing list management module (3), a boundary surface equivalent impedance management module (4), a boundary protection fixed-value quota management module (5), a transformer neutral point management module (6), a parameter calculation sheet management module (7), a circuit actual measurement parameter management module (8), a process engine (9), a fixed-value setting management system (10), a setting calculation sheet management module (11), a debugging report form management module (12), a report form amendment management module (13), a report form management module (14), a short message notification management module (15), an electronic seal (16) and a report form generator (17). The invention provides a richer data showing means; the workloads of full-time staff for setting calculation are greatly reduced; the working efficiency and the economic benefit are increased; and paperless, informationized and standardized process closed-loop management on the whole process of relay protection setting calculation is realized.

Description

technical field [0001] The invention relates to the professional technical field of electric power engineering relay protection setting calculation management. It is a paperless, informatized, standardized, and process-based closed-loop management system that realizes the whole process of relay protection setting calculation. Background technique [0002] At present, the scale of the power grid continues to expand, the speed of new substations is getting faster and faster, and the work of setting calculation and data management is becoming more and more complicated. As an important part of the work of the power grid, relay protection work has great responsibilities and strong technical aspects. , The task is heavy. Relay protection professionals are faced with various information such as power grid structure, protection configuration, equipment switching, operation mode changes, and fault conditions every day. It is very heavy to analyze, process, and count them correctly. ...

AI Technical Summary

Problems solved by technology

Although the relay protection setting calculation program has been developed and mature, due to the constraints of the complexity and diversity of relay protection calculation and management work, the whole process management of relay protection setting calculation is still a new topic. Research is just getting started

On July 26, 2010, the application number "201010235901.0" filed by Shijiazhuang Power Supply Company provides a relay protection setting value setting management system that can automatically realize setting value calculation, network sharing of setting value sheets and automatic setting of device setting values. System; setting value setting calculation and network transfer and sharing of setting value list are only part of the whole process management of relay protection setting calculation, and the closed-loop management of the whole process of relay protection setting calculation with informatization, standardization and flow has not been fully realized

[0007] 1. The reported electrical equipment parameter data is various, and there is no specification at all; the reporting methods include fax, Email, QQ, paper, etc., and the channels are different, which increases the difficulty of data collection and sorting, and often due to tight construction schedules, personnel Busy on-site work often delays the submission of materials, and even omissions occur;

[0008] 2. Information cannot be shared, and it is inconvenient to borrow materials;

[0009] 3. The data collection is out of touch with the setting calculation, which requires manual calculation to generate the parameter calculation book, which is complicated and error-prone, which is a weak link in the management of the setting calculation process;

[0010] 4. The process cannot be solidified, and it is difficult to realize the whole-process closed-loop management of relay protection setting calculation informatization, standardization and process
