ZONHAN New Energy Company Limited

Model Number: ZKJ-GT20KW Brand Name: ZONHAN Key Specifications/Special Features: ZKJ-GT (Grid-tie) model product characteristics:◆Product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard also with users’ technical requirements◆Two sets of control systems: PWM constant voltage system and three-phase dump load system◆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◆Under the strong or super-strong wind conditions, the controller can conduct constant voltage output to ensure the inverter safety running◆Under the condition of disconnected grid-connected inverter, the controller can conduct constant voltage output and wait for inverter resumption◆Three-phase dump load of the controller will automatically start and the inverter will stop grid output when the power grid is offAs soon as the grid power resuming, the controller stops three-phase dump load and the inverter will resume power supply◆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
