8D723F06PB251 is a high-performance transmission and Yaw governor of the Wind / Hydro generator set. It can be properly matched with low-voltage pitch motors to form a complete set of Wind / Hydro pitch system, providing a more reliable solution for wind and hydro power generation. This paper will introduce the application fields and working principle of 8D723F06PB251.

Application Field

8D723F06PB251 is mainly used for wind turbines and hydro turbines. Its main functions are yaw control and pitch control. In addition to providing a stable pitch control system, it can also provide good yaw control performance. It is suitable for controlling the power coefficient of power generated by wind turbines, so as to ensure the safe and stable operation of wind turbines.

In addition, 8D723F06PB251 can also be used for load sharing control and peak shaving control. It can control multiple generators connected in parallel through load sharing function, and realize the peak shaving operation of power output. Moreover, it can also control the active power compensation according to load changes, so as to realize the regulation of active power and improve the power quality.

Working Principle

8D723F06PB251 adopts the closed loop control strategy. In yaw control, proportional-integral (PI) control is used to control the electric yaw motor and make the yaw direction of the wind turbine follow the set value. While in pitch control, it utilizes PID control to make the blade pitch follow the set value and make the generator output power closely follow the wind power supply curve.

For load sharing control and peak shaving control, 8D723F06PB251 uses a two-stage control strategy. When the load change or peak demand is very large, the master governor will coordinate the power output of all paralleled generators through load sharing control, and the secondary governor will further adjust the secondary control output of each generator. In this way, the power output of each generator can be assigned according to different loads.

Briefly, 8D723F06PB251 is mainly applied in wind turbines and hydro turbines, providing various functions such as yaw control, pitch control, load sharing control and peak shaving control. The high-performance control algorithm is adopted in the control system, which ensures the power control accuracy and effectively improves the power quality.
