Integrated test system for simulated master station for intelligent substation

Abstract

The invention relates to the technical field of substations, in particular to an integrated test system for a simulated master station for an intelligent substation. The integrated test system comprises simulated master station testers, wherein the simulated master station tester A is connected with an A-zone data communication cabinet through a router and a switch; the simulated master station tester B is connected with a B-zone data communication cabinet through the router and the switch; the A-zone data communication cabinet is in communication connection with a measuring and control device and a local monitor respectively; the B-zone data communication cabinet is also connected with a comprehensive application server of an alarm direct graphic gateway machine; the A-zone data communication cabinet and the B-zone data communication cabinet are connected with a dispatching data screen; and the dispatching data screen transmits data to a regulation and control center. Due to use of an integrated tester for the simulated master station for the intelligent substation, information check work which needs to repeat twice in the past is changed into once; the closing frequency of primary equipment is reduced; the damage to the equipment is effectively reduced; and the service lifetime of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to an intelligent substation simulation master station comprehensive test system. Background technique [0002] With the development of smart grid and the improvement of digital communication technology, the digital signals of smart substations are getting larger and larger. A 220 kV smart substation needs to communicate nearly three thousand (two thousand) signals. Telecontrol information check is the work that must be carried out before the substation is put into operation. It is used to check whether the information generated in the station can be sent to the dispatching master station correctly. The main verification objects are the information point number conversion of the telecontrol device and the information points of the databases of both parties. Is the name correct. [0003] The traditional telecontrol information verification method is as follows: (1) The local sub...

AI Technical Summary

Problems solved by technology

[0004] Problems in the current calibration method: the traditional telecontrol information calibration method requires at least two signal calibrations, and the signal involving switch displacement needs to be pulled repeatedly, causing equipment damage once

And under this method, the telecontrol information verification can only be carried out after the communication network between the substation and the main dispatching station is unblocked, and the channel can only be opened after the construction of the line outside the station is completed. At this time, it is close to the power transmission time. The working period is tight, and the staff need to work overtime to complete

In addition, this method requires the cooperation between the substation end and the main dispatching station to check each control information one by one. The two parties need to be in close contact and work together. Continuous calls not only cause waste of resources, but also cause staff fatigue.
