Hydropower station centralized control center operation execution and maintenance flow anti-misoperation locking method

Abstract

The invention provides a hydropower station centralized control center operation execution and maintenance flow anti-misoperation locking method, which is characterized in that double confirmation is conducted on instructions of a centralized control center end and a power grid dispatching end when the instructions are executed, if the instructions of the two ends are inconsistent, instruction issuing is pausedor flow locking is performed, and if the instructions of the two ends are consistent, a normal instruction execution link is conducted, wherein a power plant end execution instruction comprises a maintenance flow instruction and a network operation command process, double confirmation is carried out on the centralized control center end and power grid dispatching end instructions, anti-error checking locking is carried out in the whole process of the maintenance flow management function, and even misoperation anti-error locking is completed through transformation on an electronic speed controller monitoring system, so that regulation and control whole-process closed-loop interlocking control is realized, and the method can effectively control major risks of mistaken order issuing and misoperation, creates a 'soaking' type anti-misoperation safe dispatching environment for dispatching operation, greatly improves safety benefits of cascade power stations, and is a major breakthrough for construction of intrinsically safe enterprises.

Description

technical field [0001] The invention relates to the field of electric power system scheduling automation control, in particular to an anti-misoperation locking method for the operation execution and maintenance process of a centralized control center of a hydropower station. Background technique [0002] At present, the dispatching and production management of the remote centralized control center (hereinafter referred to as "centralized control center") of cascade hydropower stations in some domestic river basins is based on the advanced "control integration" model, and is mainly responsible for power dispatching, reservoir dispatching, operation monitoring, Remote control, remote accident handling and other work services. In recent years, the dispatching business environment has become more and more complex. Services such as maintenance, operation, and power generation planning coordinated by power grid dispatching at all levels and centralized control center dispatching s...

AI Technical Summary

Problems solved by technology

The original dispatching business management mode, faced with increasingly frequent operations and more and more maintenance tasks, will result in poor coordination of multi-level control operations, lack of switching tracking and safety verification, and at the same time imprison the work efficiency of dispatchers and quality, it is very easy to cause power safety accidents such as wrong order and misoperation
