Problems solved by technology

The premise of this method is that the hydraulic design parameters of the pump must be known, which increases the difficulty for third parties to use this method, and the accuracy of numerical simulation cannot be guaranteed
[0006] In addition, identifying the characteristics of the water pump system based on historical operating data is similar to the model test, but there is only one pump in the model test. system, and adjusting the pumping system adds to the difficulty

Abstract

The invention belongs to the technical field of intelligent operation and maintenance of hydraulic machinery, and particularly relates to an online identification and optimal regulation and control method and regulation and control system for the operating characteristics of a water pump system. The online identification and optimal regulation and control method for the operating characteristics of the water pump system comprises the steps that S100, basic information of the water pump system is collected; S200, real-time data of the water pump system are collected; S300, a characteristic model of the water pump system is constructed according to the basic information and the real-time data, and the characteristic model is updated in real time; and S400, the water pump system is regulatedand controlled according to the characteristic model of the water pump system. A theoretical characteristic curve provided by a manufacturer is utilized, and a water pump system model can be generatedunder the condition of a small data volume; and an improved heuristic algorithm is introduced, so that the method can jump out of a locally optimal solution quickly, and approaches a globally optimalsolution.

Description

technical field [0001] The invention belongs to the technical field of intelligent operation and maintenance of hydraulic machinery, and in particular relates to an online identification and optimization control method and control system for the operation characteristics of a water pump system. Background technique [0002] In recent years, with the continuous development of industrial digitalization, networking, and intelligentization, industrial systems are facing more and more challenges in realizing intelligent operation and maintenance. [0003] Water pumps are widely used components in the industrial field, and their total electricity consumption accounts for more than 20% of the national electricity consumption. Multiple pump units (hereinafter referred to as "pump system") are important equipment in the pipe network system. Due to the possible mismatch between the performance of the two, this also leads to hydraulic imbalance in the pipe network system. Therefore, i...
