description: Topic of the final qualifying work: âStudy of the harmonic components of voltage in an isolated power supply system of a liquefied natural gas plant.â This work is devoted to the study of harmonic voltage distortions on high-voltage and low-voltage buses of the power supply system of an LNG plant. During the work, the following tasks were completed: 1. A model of the PSS of a natural gas liquefaction plant was created in the Simulink software package. 2. The model was launched in various modes and voltage oscillograms were taken from the required buses. 3. The results obtained in the model and real data from the IPSA electrical laboratory are compared 4. A study was conducted of the operation of harmonic filters installed at the enterprise 5. Optimized filter settings for better suppression of problematic harmonics. All studies and calculations were carried out using technical literature, as well as computer programs Matlab Simulink and CAD MathCad. The information and results obtained may be of practical value in the design of future enterprises that involve the use of frequency converters to resolve issues regarding the quality of electrical energy.
