- Abstract
The hydraulic wind turbine could not directly generate electricity after being connected to the grid, it was necessary to control the active power. The wind energy had randomness and volatility. The system had time-varying and nonlinear characteristics, and it was necessary to solve the accurate control of the active power of the fans under external disturbances. The nonlinear problem of the hydraulic main drive system was solved by feedback linearization. The nonlinear disturbance observer was used to quickly and accurately observe the influences of external disturbances on the output power of the system. An active power compensation controller under mismatched disturbances was proposed to accurately compensate the influences of disturbances on the output power of the system, and the active power control strategies of the hydraulic wind turbine were obtained. Based on the semi-physical simulation experimental platform of 30 kV * A hydraulic wind turbine, the output active power of the unit may accurately follow the target speed changes. The absolute error of active power is as + 0.05 kW, and the steady-state errors are within the range of 3%~5%.
