Embodiment Construction

[0031] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. range.

[0032] In the city water supply, the pressure value set by the PLC control system is output through the pressure control model. The PLC control system compares the real-time pipe network water pressure value with the pressure value set by the system, and the PLC controller obtains the difference between the two. Then the control informati...

Abstract

The invention provides a water supply energy consumption reduction method based on a pressure control model and a PLC, and belongs to the technical field of water supply. A hybrid genetic method is adopted to calculate an optimal pressure control curve and the optimal pressure control curve is sent to the PLC, and flow regulation is performed by a water pump rotation speed regulation method to uniformly schedule the operation of a water pump unit. According to a pressure value fed back by a water pipe network in real time, the power frequency conversion switching of each water pump is automatically controlled, and the pumps are automatically inverted by accumulative timing; and at the same time, a water supply system is regulated according to the real-time water pressure deviation, and control parameters are sent to the frequency converter, which regulates the operation frequency of the water pumps and the water supply flow of the water pipe network, so that finally the purpose of stabilizing the water supply pressure, saving energy and reducing consumption are achieved.

Description

Technical field [0001] The invention relates to water supply technology, in particular to a method for reducing energy consumption of water supply based on a pressure control model and PLC. Background technique [0002] my country is a country with a shortage of water resources. For a long time, technology has been relatively backward in municipal water supply, high-rise building water supply, and industrial production circulating water supply, and the level of automation is low. With the development of my country's social economy, the continuous improvement of people's living standards and the continuous increase of various types of communities in the city, the requirements for the construction of urban water supply infrastructure are getting higher and higher. The reliability, stability and economy of water supply directly affect people's normal life and work. [0003] The traditional water supply methods include: constant speed pump pressurized water supply, water tower high wa...
