Robust Automatic Control System of Dependent Skewness Measurement Logic

Based on the influence of robust automatic control system and skewness measurement logic on tidal power generation, this paper proposes a method of robust automatic control system of dependent skewness measurement logic (DSML). It establishes tubular turbine robust automatic control model, and expands the application of skewness measurement logic algorithm in the field of tubular turbine generation frequency system. At the same time, on basis of researching the basic principle of AC excitation tidal power generation system, it designs the mathematical model of AC excitation generator under the two-phase rotating coordinate system, introduces the stator flux linkage vector orientation method, and through adjusting the excitation independently adjusts the active and reactive power of generator. The experimental results show that the method has good control effects for tubular turbine automatic control system, also can reduce the wear degree of tubular turbine, improve the efficiency of the tidal power generation, and have certain reference significance for tidal power generation, wind power generation and hydroelectric power generation.
