Embodiment

[0042] Such as figure 2 As shown in , the remote control and intelligent anti-misoperation locking rules and strategies of the cascade hydropower station are simple process diagrams in each function of the system. Between the operation command execution and the maintenance work management function, the execution of each link is mutual anti-misoperation locking and network order function operation command execution The anti-mistake locking of each link, if the check is passed, the operation can continue, otherwise, the lock will continue to operate, the corresponding information will be prompted, and the check will not pass;

[0043] Such as image 3 As shown in , in the power outage link of centralized control center maintenance, using the function of anti-misoperation blocking of dispatching orders, in the link of ordering operation order tickets, the operation order ticket of the centralized control center side and the operation order of the power grid side are locked in li...

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...
