| Abstract: | Taking the hydraulic wind turbine as the object, aiming at the closed loop system of low-speed fixed displacement pump high-speed variable motor speed increasing transmission, the working principle of the hydraulic wind turbine is explained, the mathematical model of the main drive system of the fixed displacement pump-variable displacement motor is established, and the 37 kW hydraulic wind power generation test platform is built. On the basis of the system constant current source control, the PID controller is applied to compensate the swash plate swing angle, the motor speed characteristics and the anti-interference performance of the control method are analyzed. Research has shown that the fixed displacement pump-variable displacement motor hydraulic speed-increasing transmission control system can realize the stable speed control of the electrically excited synchronous generator. |
