Wind Turbine Grid Tie Controller

Wind Turbine Grid Tie Controller

Characteristics and Features
1. Our FKJ-GT wind turbine grid tie controller is manufactured to comply with the JB/T6939.1-2004 industrial standard, GB/T 19115.1-2003 national standard, as well as users' technical requirements.
2. It comes with two sets of control systems, including PWM constant voltage system and three-phase dump load system.
3. The PWM constant voltage control system is 120% of the rated power of the wind turbine. In case of exceeding the power range of PWN, the three-phase dump load system will start up automatically in a few seconds and stop after approximately ten or twenty minutes. At that moment, the wind turbine will automatically re-start to resume the power supply, ensuring the safe operation of the wind turbine generation system.
4. Under the condition of strong or super-strong winds, our device is able to offer a constant voltage output, guaranteeing the safe running of the inverter.
5. If the grid-connected inverter is disconnected, it also conducts a constant voltage output and waits for the resumption of inverter.
6. When the power grid is off, the three-phase dump load of the wind turbine grid tie controller will automatically start and the inverter will stop the power grid output. Immediately the grid power is resumed, our equipment will enable the three-phase dump load to stop and the inverter to resume the power supply.
7. In terms of the different wind turbine generators, the controller can be equipped with mechanical yawing, furled empennage, mechanical/ hydraulic /pneumatic/ electrical magnetic system, as well as other brake functions.
8. Designed with a surge arrester, the transient over voltage of wind generator will be kept within the allowable voltage range of this grid-tie controller or the strong lightning current will be diverted into the earth directly, thus preventing the equipment from damages.
9. There are many LED status indicators can be found on the front panel and they are respectively wind turbine, dump load, three-phase dump load delay time, under voltage, grid power, and DC output voltage indicators.
10. Its voltmeter indicates the DC output voltage of this device.
11. The wind turbine grid tie controller is applied with emergency stop switch. In case of emergency, press down the emergency stop button in the front panel to cut off all power supply and the wind turbine will instantly perform the three-phase dump load.
12. The manual switch of three-phase dump load is also available. By using this switch, the wind turbine will carry out the three-phase dump load forcibly.
