description: This master's thesis deals with issues of noise immunity and measures to protect equipment at one of the facilities of the distribution and transshipment station Vysotsk âLukoil-IIâ. The company is located in the Leningrad region on the shores of the Vyborg Bay. The developed power supply system of a facility located on the territory of the enterprise is much more reliable and energy efficient.
An overvoltage analysis was performed in the power supply system, the power supply system was upgraded, namely, the replacement of luminescent lighting with LED lighting, a lighting calculation was made, short-circuit currents were calculated, and protective devices were selected. Developed methods for calculating and modeling the existing problems of the object, considered the frequency spectra of overvoltages and calculated the coefficients of non-sinusoidal voltage. Worked out to improve the quality of electricity and energy efficiency of the power supply system, namely, selected SPD devices of various classes to protect equipment, as well as network filters to suppress high-frequency interference.
