Embodiment Construction

[0014] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0015] A pumping station equipped with three units: the water level of the forebay is divided into 11 operating points from -1.78m to 0.78m [m 1 、m 2 、m 3 ...m 11 ], one point every 10cm; the water level of the back pool is divided into 8 operating points from 2.2m to 2.9m [n 1 , n 2 , n 3 ...n 8 ], a point every 10cm; set the blade angle of the first unit from +8 0 ~-8 0 Divided into 17 operating points [a 1 、a 2 、a 3 ...a 17 ], every 1 0 One operating point; change the blade angle of the second unit from +8 0 ~-8 0 Divided into 17 operating points [b 1 , b 2 , b 3 ...b 17 ], every 1 0 one operating point; change the blade angle of the third unit from +8 0 ~-8 0 Divided into 17 operating points [c 1 、c 2 、c 3 ... c 17 ], every 1 0 an operating point.

[0016] First, control any one of the three units to start up (start ...

Abstract

The invention discloses a computer control technology based energy-saving method for a water transfer pumping station with a full-modulation axial-flow pump. The computer control technology based energy-saving method is characterized in that power consumption under all operation states of the pumping station is measured and stored through experiments. When the pumping station accomplishes flow or lift required by certain appointed task, all schemes capable of accomplishing the task are automatically compared and the optimal operation scheme is selected; and a computer automatically regulates parameters such as front tank water level, rear tank water level, a blade angle and number of power-on machines of the pumping station, so that the pumping station operates under the optimal scheme. The pumping station always operates in the most power-saving state on the premise of accomplishing certain task, so that the power-saving purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of computer control, and in particular relates to an energy-saving method for a fully-adjustable axial-flow pump water delivery pumping station based on computer control technology. Background technique [0002] The power saving of pumping stations is not a new problem, especially today when energy saving and emission reduction has become a national strategy, it has attracted more and more attention. The pumping station of the large-scale fully adjustable axial flow pump unit consumes a lot of power and has a lot of adjustable volume. This provides the necessity and possibility for us to engage in energy-saving operation. However, there is currently no better way to ensure that the pumping station can operate under the most energy-saving conditions. The wide application of computer control technology in the operation of pumping stations provides a broad platform for us to choose the best energy-saving sche...
