Our company has been engaged in wind controller for over 20 years and we made continuous updating relying on the practical experience for many years and in accordance with the characteristics of wind power generation. This system runs safely, stably and reliably with high work efficiency and long service life.
1. Two sets of control systems：PWM constant voltage system and three-phase dump load system.
2. PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the three-phase dump load will automatically start immediately. After 10-20 minutes, the three-phase dump load will stop and the wind turbine will re-start to resume power supply to ensure the safe running of the overall wind turbine generation system.
3. Under the strong or super-strong wind conditions, the controller can conduct constant voltage output to ensure the inverter safety running.
4. Under the condition of disconnected grid-connected inverter, the controller can conduct constant voltage output and wait for inverter resumption.
5. The three-phase dump load of the controller will automatically start and the inverter will stop grid output when the power grid is off. As soon as the grid power resuming, the controller stops three-phase dump load and the inverter will resume power supply.
6. For the different wind turbine generator type, the controller can be equipped with mechanical yawing, furled empennage, mechanical or hydraulic, pneumatic, electric magnetic and other brake functions.
7. The inside of the controller is equipped with surge arrester. Contain the over voltage into the wind turbine under the bearable voltage of the equipment or system. On another way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.
8. The below LED status indication can be found on the front panel: indications of wind turbine, dump load, three-phase dump load delay time, under pressure, grid power and DC output voltage.
9. Voltmeter indication: Indicate the controller DC output voltage.
10. The controller is equipped with emergency stop switch; in case of emergency, press down the emergency stop button in the front panel to cut off all power supply of the controller and the wind turbine will immediately carry out three-phase dump load.
11. The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump load forcibly.
12. Under working conditions, the load discharger equipped for our equipment will generate high temperature, please place it in a place beyond 2 meters away from the main engine of the controller with good ventilation and radiation inaccessible to humans and animals to avoid scalding. Strictly forbid covering by other articles or using in the environment with combustible and explosive gas to avoid fire accidents.
13. Connect the load discharger strictly abiding by the wiring diagram. During the use of our equipment, the removal of the load discharger is strictly forbidden. Or else, the wind turbine will be damaged by runaway accident due to lost control of the wind turbine generator and the controller may be destroyed due to over voltage!
