Operation authorization system of power primary equipment

Abstract

The invention provides an operation authorization system of power primary equipment. The operation authorization system comprises a dispatching end authorization server, a background verification terminal, a switch and a plurality of primary equipment control loop authorization devices, wherein the background verification terminal is connected with the scheduling end authorization server, the scheduling end authorization server is connected with each primary equipment control loop authorization device based on the switch, and each primary equipment control loop authorization device is arrangedin a primary equipment control loop; the background verification terminal acquires authorization request information of the primary equipment to be operated, and the information is sent to a scheduling end authorization server; the scheduling end authorization server processes and encrypts the authorization request information; and the encrypted information is sent to the target primary equipmentcontrol loop authorization device through the switch, and the target primary equipment control loop authorization device performs authorization verification on the received information and controls the primary equipment control loop where the target primary equipment control loop authorization device is located to be switched on or switched off according to a verification result.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to an operation authorization system for primary power equipment. Background technique [0002] With the advancement of the State Grid Corporation of China's three sets of five majors, many 500kV substations have realized fewer people on duty, 220kV has realized few people or no one on duty, and most of 110kV and below substations have realized centralized monitoring, remote control switches, automatic switching capacitors and Reactors, real-time online automatic power generation control, and automatic voltage control technologies are widely used, and have achieved great economic and social benefits for the progress of electric power production. [0003] However, while these remote operation controls bring convenience to production, there is a great risk of production safety. There is a risk of losing control rights after hackers from Ukraine invaded the power monitori...

AI Technical Summary

Problems solved by technology

[0005] Based on at least one of the above technical problems, the present invention proposes a new operation authorization system for primary power equipment, which can effectively ensure the legitimacy of remote-operated primary equipment, improve the safety of power system operation, and fundamentally solve the traditional remote control system. The problem of low security level caused by mobile devices directly responding to dispatching instructions
