Embodiment Construction

[0102] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0103] Such as Figure 1-5 as shown,

[0104] 1. Establish a time-space hierarchical optimization operation model system for the series-parallel cascade pumping station water delivery system

[0105] (1) First, define the optimal operation connotation of series-parallel cascade pumping station water delivery system as follows: for single-stage pumping station, series system, and parallel system, assuming that the system is in a relatively balanced state, on the basis of meeting certain water delivery tasks and boundary conditions, according to Optimizing goals at different levels (efficiency, daily, mid- and long-term), taking the operation plan (unit on / off combination, blade angle / speed) and hydraulic parameters between steps (water level, flow) in each pumping station as decision variables to seek the optimal An optimal single-stage pumping station...

Abstract

The invention discloses a space-time hierarchical and operation-optimized method and system for the serial-parallel, cascade pumping station water delivery system. The method includes the steps that establish a complete set of space-time hierarchical and operation-optimized theoretical system for the serial-parallel, cascade pumping station water delivery system. It establishes successively in the space dimension, single level pumping station, serial system, parallel system operation-optimized model system; in the three-model system, it establishes successively the three layers of operation-optimized model: system operation efficiency, daily, mid-term and long-term, according to different optimization targets in the time dimension and considering the delays by the startups and shutdowns of the pumping station as well as other factors. It figures up a multi-layered optimized operation plan, and realizes the step-by-step optimized decomposition of the operation plan in the time (mid, long-term, daily, hourly) dimension and space (parallel system, serial system, single-level pumping station) dimension, including the distribution of water within different time periods, the optimization plan for the staircase hydropower, the optimized operation plan for the internal units of the pumping station. This method solves the tough problem of figuring up an optimized operation for the serial-parallel cascade pumping station water delivery system, due to the complications and dynamics of control and operations.

Description

technical field [0001] The invention relates to a time-space layered optimization operation method and system for a water delivery system of series-parallel cascade pumping stations. Background technique [0002] In order to realize the rational allocation of water resources, a number of long-distance, cross-basin large-scale series and parallel cascade pumping station water delivery projects have been built both at home and abroad. Such as the Yellow River Diversion Project, the East Route Project of the South-to-North Water Diversion Project, etc. The total installed capacity and energy consumption of this type of project are large, and the corresponding energy-saving potential is huge; the cascades (rivers) are mostly rigid, semi-rigid in series or parallel, with small storage capacity and difficult operation and control. Taking the newly built cascade pumping station water delivery project on the eastern route of the South-to-North Water Diversion Project as an example,...
