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 a hydropower station intelligent startup and shutdown method for a frequency modulation market, which comprehensively considers various factors such as an active plan curve, asecondary frequency modulation reserved capacity, a limited operation area, a unit startup and shutdown priority and the like, and the requirement of safe and stable operation of the hydropower station is met on the premise of firstly meeting the active power regulation requirement of scheduling on the power station. The method is suitable for hydropower stations of different types of hydroelectric generating sets including a conventional type set, a single-suggested operation area set and a double-suggested operation area set. Therefore, the difference of the types of the units does not formapplication obstacles any more, and the method has wide 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...
