Abstract:

Purpose. Development of a new research area related to electroanalogy methods used for modeling working processes in electromechanical systems of water supply networks.

Methodology. The methodology of the research is based on applying power electronics methods used while analyzing electromagnetic processes as well as methods of circuit modeling with the use of schemes of electric models.

Findings. It is shown that the circuit design of electric models of electromechanical systems with piston pumps differs from circuits of such systems with centrifugal pumps. The circuits of the former ones are simpler and can be realized in the form of specific physical objects. Not every circuit with centrifugal pumps is physically realizable. However, it does not present an obstacle for their use while analyzing electromagnetic processes in electric models, as evidenced by the agreement of the results of analytical studies with the results of circuit modeling.

Originality. The authors’ research proved possibility of developing electric models of the electromechanical systems with piston and centrifugal pumps constructed on the common basis which is presented by electric energy converter – a rectifier.

Practical value. Development of electric models of electromechanical systems of water supply networks allows modeling and investigating working processes in water supply networks.
