A METHOD OF COMPUTER MODELING OF POWER SUPPLY SYSTEMS FOR HIGH-CAPACITY PUMPING STATIONS

The article examines the study of the power supply system for high-power pumping stations using computer modeling techniques. An 8 MW synchronous motor, which serves as the electric drive for the pumping units, was selected as the load on the station's power supply system. Computer modeling involves the use of certain strict steps, the completion of which allows for the desired result to be achieved. The initial stage of modeling any system is the collection of data and parameters for each part of the object under study, as well as the determination of the calculation parameters. Calculation data is necessary when modeling complex systems, as in such cases, passport or reference technical data is insufficient. The second stage involves drawing up structural diagrams and mathematical models of individual parts or the entire system at once. Since the power supply system of pumping stations consists of complex electrical and electro technical components, a mathematical description will be produced separately for each part of the system: transformers, power lines, etc. Modeling complex systems as a whole is a very difficult task, so the proposed methodology is convenient and expedient in terms of simplifying the modeling of complex tasks.
