| Popis: | In this article we define the problem, formulate the theme and justify the relevance of the tasks to be solved, which depend on the object under study. The object under study was determined and the structure and basic elements were analyzed. It was found that an auxiliary transformer and from eight to ten outgoing lines are connected to one section of bus of a power transformer of the field substation. Mathematical models of electrical systems of a field substation and a pumping station for transporting oil flows with shop transformers, individual, node and centralized compensating installations have been developed. In mathematical models which take into account the change in the volume of transported oil into a common pipeline, asynchronous electric motors of pumping units with a capacity of 75, 132 and 160 kW with low-voltage frequency converter are considered. Using the MATLAB Simulink software package, we developed mathematical models for 75, 132 kW (132 and 160 kW) electric drives of pumping units. These models take into account emergency operation, i.e. when two pumping units operate from the same power source. The study of the operating modes of the electrotechnical complex of a booster pump station during direct start-up from the electrical network was carried out using its simulation model developed in the PSCAM software package. The article presents the simulation results in the form of graphs showing relationships between frequency buildup, electromagnetic and dynamic moments and the stator current of the asynchronous motor. Scientific novelty of the present work is in the developed mathematical and simulation models which take into account parametric perturbations in external and internal distribution electrical networks, and allow one to determine the energy parameters of operating modes in all sections and elements of the outgoing line, taking into account reactive power compensation in transient and steady-state conditions. |
