Electrical Modeling of Workflows in Electrical Systems of Water Supply Networks

The article presents the results of research aimed at developing of scientific direction, which provides for analysis of energy processes in electromechanical systems of water supply networks using electric methods of modeling their workflows. The set of energy components of water supply network is considered as an electromechanical system. The components are electric motor, transmission mechanism and pump system for supplying fluid to the pump. The main part of the electrical model of electromechanical system is a converter of electrical energy (rectifier). Circuits single-phase and three-phase rectification, known in energy electronics, are used in models of electromechanical systems that contain piston pumps. The converter circuits of electrical energy are developed by authors for the implementation of electric models of electromechanical systems that contain centrifugal pump. It is divided into three levels depending on the complexity of circuit engineering realization and characteristics of electromagnetic processes. The method for analysis of electromagnetic processes in such models is developed and the adequacy of results of electrical modeling to real workflows in simulated water supply networks is proved.
