variable pitch

Firstly, based on the aerodynamic analysis of wind turbine, the variable-pitch control strategy of the wind turbine was derived.

Therefore, to carry out research on the variable pitch control system of wind turbine and its drive system has important significance.

The results of numerical simulation show that the pump with the variable-pitch inducer can improve the anti-cavitation performance.

First, traditional PID variable variable pitch control system and conventional fuzzy variable pitch control system are established.

The good or bad of variable pitch system affects wind generating set efficiency, safe operation and stable operation to a large extent.

Variable-pitch inducers can be fixed before impellers to lower the NPSHr of pumps efficiently.

In this paper, the research for the control system begin with studying controller of variable pitch control system.

In variable-pitch systems, the feedback of servo motor operating conditions and blade angles are provided by rotary encoder.

This paper has mainly studied the novel variable-pitch variable-speed wind turbines and Yaw-control system of wind turbine generator.

This provides a theoretical basis for latter variable pitch design of hardware and software.

It introduces the motion requirement and the structural characters of yawing and variable pitch.

Moreover, satisfactory cavitation performances were achieved by using the proposed method to design the variable-pitch inducer.

In this paper, the mathematical model of DFIG and variable pitch system is established.

The method can be used on modeling other variable pitch screw.

"It's a variable-pitch propeller, which is like having gears on a bike, " Land says.

The horizontal anger has a variable pitch.

If this value is set, the font is a variable pitch font.

There is a variable pitch of the joystick to change the tilt rotor plane in order to achieve control of flight direction.
