In the article, the power consumption of pump station control systems was simulated in the iThink software package. For this purpose, simulation models of two control systems to control the oil level in the pump station were developed. In the first of these, only the frequency converter was used as a control element, and in the second one, in addition to the frequency converter, a fuzzy controller was also involved. A simulation of oil level control process, presented in a graphical form, was conducted, as well as the graphs for energy consumption of the pumps were obtained. Based on the initial and obtained data, the efficiency of the considered control systems was compared, and also dependency graphs for energy consumption of the systems using only a frequency converter and using a frequency converter and a fuzzy controller were obtained.Analysis of simulation models showed that it is more economical and safe to use the control circuit with a frequency converter and a fuzzy controller.
