Operating and scheduling control method for cascade pump station water delivery system

Abstract

The invention relates to an operating and scheduling control method for a cascade pump station water delivery system. The method includes the steps of establishing a hydraulic simulation model, establishing a water level-flow-storage volume relation of channel segments, judging the working condition in real time, conducting control on the before-station water level and after-station water level of each pump station within the extreme value range, conducting control on the condition that the water level exceeds the maximum operating water level, and conducting control on the condition that the water level exceeds the minimum operating water level. According to the method, in the cascade pump station water delivery system, the hydraulic simulation model is established, the water level-flow-storage volume relation of the channel segments is calculated, and the control scheme is established according to the control method under the real-time working condition, wherein if the before-station water level and after-station water level of each pump station are within the extreme value range, the time variation rule of the before-station water level or after-station water level of each pump station is predicted to provide the control scheme, and if the before-station water level and after-station water level of one pump station exceed the extreme value range, the control measure is taken immediately. The control scheme is proposed to provide technical support for manual scheduling and guarantee safe operating of the cascade pump station water delivery system.

Description

Operation scheduling control method of cascade pumping station water delivery system technical field The invention relates to an operation scheduling control method of a cascade pumping station water delivery system, and is an adjustment control method of a long-distance water delivery system. Background technique The cascade pumping station water delivery system consists of pumping stations (trash racks, water pump devices, motors, other auxiliary devices, etc.), water diversions and channels and other equipment and facilities. Through pumping stations to lift water and channels (pipelines) to deliver water, to achieve Rational allocation of water resources. Due to the complexity of the cascade pumping station water delivery system itself and the dynamics of the operating conditions, it faces great difficulties in the operation scheduling and control process. The traditional manual scheduling method often sacrifices economic benefits for safety. For the operation sched...

Due to the complexity of the cascade pumping station water delivery system itself and the dynamics of the operating conditions, it faces great difficulties in the operation scheduling and control process. The manual scheduling method often sacrifices economic benefits to ensure safety

For the operation scheduling control of cascade pumping station water delivery system, the existing researches are all aimed at the control objectives of the operation scheduling scheme of cascade pumping station water delivery system, using PI control algorithm, ID control algorithm, PID control algorithm, etc. to formulate control schemes, often neglecting In the actual operation and scheduling process, the water flow of cascade pumping stations is unbalanced, and the water level in front of (behind) the pumping station exceeds the extreme value range. The existing methods cannot be directly applied to the cascade pumping stations under such conditions. Water system operation scheduling control
