Embodiment Construction

[0028] Such as Figure 1-3 As shown, the optimal control method of the multi-year regulation of the drought-limited water level of the reservoir in the present invention is further described in detail with the Longyangxia Reservoir with the multi-year regulation ability of the main stream of the Yellow River as an example:

[0029] Step 1. Collect the data required for the optimal control model of the multi-year drought-limited water level of the reservoir, that is, collect the reservoir water level data at the beginning of the dispatch cycle, the runoff process data within the dispatch cycle, the characteristic parameters of the reservoir and the power station, and the power station through the data collection module. Output characteristic parameters, comprehensive reservoir utilization requirement data, and water demand process data of water users downstream of the reservoir;

[0030] Step 2, establish and store the minimum period analysis method for regulating the reservoir...

Abstract

The present invention discloses an optimum control method for a carry-over storage drought limitation water level and a dedicated control system. The method comprises: 1, collecting data required by an optimum control model for a carry-over storage drought limitation water level; 2, building and storing a minimum period method of a carry-over storage inflow runoff; 3, building and storing agricultural water marginal benefit based on a marginal benefit decreasing theory; 4, building and storing the optimum control model of the carry-over storage drought limitation water level; 5, solving the optimum control model of the carry-over storage drought limitation water level; and 6, generating and outputting a carry-over storage drought limitation water level control strategy, namely, the drought limitation water level control strategies corresponding to different degrees of the drought limitation water level are displayed through a drought limitation water level optimum control rule and a drought limitation water level optimum control surface. The optimum control method for a carry-over storage drought limitation water level and the dedicated control system are able to build a carry-over storage drought limitation water level optimum control model through the estimation of the inflow forecast and the drainage basin drought in later period so as to provide an effective way for determination of the carry-over storage drought limitation water level.

Description

technical field [0001] The invention relates to the technical field of drought resistance and disaster reduction of reservoirs, in particular to an optimal control method and a special control system for adjusting the drought-limited water level of reservoirs for many years. Background technique [0002] Multi-year regulating reservoirs are usually located at the "lead" position of the cascade reservoir group, and play a compensating role in the cascade reservoir group. The quality of its operation and scheduling directly affects the benefits of the entire cascade reservoir group in the next year or several years. The literature research shows that the existing achievements mainly focus on the research on regulating the year-end water level of the reservoir for many years for power generation, shipping and other issues, with the goal of improving economic efficiency. [0003] The concept of drought limit water level refers to the water level of rivers, lakes and reservoirs t...
