Nguyen V. Optimization of parameters of the regujators of gas diesel-generating units of the marine power plants with a sharply varying loads.

Object of research: ship power system based on gasdiesel-generators. The purpose of research: improve the efficiency and quality of electricity self-contained (ship) of electric power systems based on gas engines by optimizing the parameters of the regulators of gasdiesel-generating units of ship power stations. Methods of research: state-space method, methods of control theory (the method of logarithmic amplitude-frequency characteristics, methods of optimizing the parameters of the regulators), the elements of fuzzy logic theory, mathematical modeling methods; microprocessor technology. Theoretical and practical results: first research-based power surges-dips when changing of power load was developed forecasting method and such changes; developed refined dynamic model of a gas engine, which incorporates the effect of the turbocharger, and the nonlinear properties of the real parameters of the fuel; developed a simplified dynamic model of a synchronous generator to solve the problem optimizing the parameters of the gas engine and controls the excitation system of synchronous generator; developed microprocessor control system gas diesel - generator set power of 500 kW. Degree of introduction: are used in educational process NUOS and are recommended for use in development PLC DEP "Delmor", Mykolaiv and «Shipbuilding science and technology institute», Ha Noi city, Vietnam. Sphere of use: ship power system.
