Embodiment Construction

[0027] Such as Figure 4 As shown, the pumping station energy-saving optimization control method of the present invention includes the following steps:

[0028] Step 1. The liquid level difference E, the liquid level change rate EC, and the number U of the pumps to be activated are divided and graded respectively;

[0029] Step 2. According to the Gaussian function, establish the membership degree table of the gear and series of the liquid level difference E, and set the gear of the liquid level difference E, the gear of the number of starting pumps U, and the gear of the liquid level change rate EC the state table;

[0030] Step 3. According to the membership table and the status table, the weighted average method is used to calculate the control relationship table for the classification of the liquid level difference E, the classification of the liquid level change rate EC and the classification of the number of pumps U;

[0031] Step 4. According to the formula y1=10 / (L2-...

Abstract

The invention provides an energy conservation optimization control method for a pump station. The liquid level difference E, the liquid level change rate EC and the pump starting number U are graded and classified; the membership table between the gear and the class number of the liquid level difference E is established according to the gauss function, and a state table for the gear of the liquid level difference E, the gear of the pump starting number U and the liquid level change rate EC is set; a control relation table among the classification of the liquid level difference E, the classification of the liquid level change rate EC and the classification of the pump starting number U is obtained through calculation of a weighted average method according to the membership table and the state table; and the relation table is controlled correspondingly according to a formula, the class number of the pump starting number U is obtained, afterwards the number of pumps needing to be started is obtained, and the pumps are started. The invention further provides an energy conservation optimization control system, and intelligent energy conservation optimization control over the pump station is achieved.

Description

technical field [0001] The invention relates to an energy-saving optimization control method and system for a pumping station. Background technique [0002] Due to the high degree of nonlinearity, dynamic mutation, scattered sensing elements and actuators, complex information structure and other reasons in the current typical complex sewage treatment system, it is impossible to find an accurate mathematical model, and there are some uncertainties. These are difficult to describe with precise mathematical models. The control method of the traditional lifting pump station adopts liquid level control. When the water level reaches a certain value, the corresponding submersible pumps are turned on in turn. [0003] The problems in the traditional control method of the lifting pump station are that the pump starts frequently and the wear of the pump is different, resulting in a short replacement cycle of the pump and a large amount of maintenance. Traditional control methods lac...
