Problems solved by technology

However, this method does not take into account the problem of high-head giant hydropower units avoiding the restricted operation area, nor does it consider the complexity caused by factors such as the reserved capacity for secondary frequency regulation and the diversity of unit operation area combinations, so it is difficult to meet the requirements of conventional hydropower stations. automation control requirements

Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the examples, which are explanations of the present invention rather than limitations.

[0039] see figure 1 , a method for intelligent start-up and shutdown of hydropower stations facing the frequency modulation market, comprising the following steps:

[0040] S1000) Determine the various parameters of the hydropower station participating in the intelligent start-up and shutdown, including the planned total active power setting value of the hydropower station based on the active power plan curve, the reserved capacity for secondary frequency regulation, the operating range of each unit under the current water head, and the number of participants in the intelligent start-up and shutdown calculation. Units, setting start-up priority and shutdown priority, generating or non-generating status of the units participating in the intelligent start-up and shutdown calculation, and the minimum nu...

Abstract

The invention discloses an intelligent start-up and shutdown method of a hydropower station facing the frequency regulation market, which comprehensively considers various factors such as the active power planning curve, the reserved capacity of the secondary frequency regulation, the restricted operation area, the priority of starting and stopping the unit, and firstly meets the dispatching requirements for the power station. Under the premise of the active power adjustment requirements, the requirements for the safe and stable operation of the hydropower station's own units are taken into account. The present invention is applicable to hydroelectric power stations of different types of hydropower units including conventional units, single-recommended operation area units, and double-recommended operation area units; so that the difference in unit types no longer constitutes an application obstacle, and the present invention has a wide range of applications. applicability.

Description

technical field [0001] The invention belongs to the technical field of hydroelectric power generation control, and relates to an intelligent startup and shutdown method of a hydropower station facing the frequency modulation market. Background technique [0002] At present, most of the unit start-up and shutdown operations of hydropower stations are automatically completed by the programmable logic controller (PLC) of the local control unit (LCU) of the computer monitoring system through a preset sequence control process without human intervention. The automatic startup and shutdown function greatly reduces the workload of operators, eliminates the possibility of human error, and improves the success rate of startup and shutdown. However, operators still need to manually trigger the startup process or shutdown process, so there are the following problems: [0003] 1) The remote centralized control of multiple hydropower stations through the basin centralized control center o...
