 wind turbine charge controller

The On grid wind turbine system is composed of wind turbine, on grid controller, on grid inverter, metering device, and power distribution system. Wind energy is converted into AC electrical energy by the wind turbine, and then converted into DC electrical energy by the on grid controller, and then DC electrical energy is converted into AC electrical energy of the same frequency and phase as the grid by the on grid inverter, and part of the power is supplied to the local load. Surplus power is fed into the grid.

h screen display. Visually display the working status of the controller. Rich data display: real-time wind turbine voltage and current, solar panel voltage and current, DC output voltage and current, and cumulative power generation


3 The technical parameters of the controller can be adjusted through the touch screen. The control parameters can be adjusted for different wind turbines.


4 Two sets of control systems are adopted, PWM constant voltage and constant current system +three-phase braking system.


5 Current control, wind speed control and wind turbine speed control can be added, and the control parameters can be set.


6 In the case of strong winds, the constant voltage and constant current output of the controller provides DC constant voltage power to ensure the normal operation of the inverter.


7 When the on grid inverter is offline, the controller outputs a constant voltage and waits for the inverter to return to work.


8 When the grid is cut off, the controller will automatically control wind turbine brake and the inverter will stop output to grid. When the grid resuming, the controller stops brake wind turbine and the inverter will resume power supply.


9 The inside of the controller is equipped with surge protector. 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.


10 Controller has an emergency stop switch, in case of emergency, when the button is pressed the front panel, cut off all power supply of the controller and the wind turbine will immediately brake.


11 The controller has a manual brake switch. To using this switch, the wind turbine will brake.


12 Using Modbus communication protocol. Convenient for customers to conduct secondary development.


13 Support RS485, WiFi, GPRS, Ethernet and other communication methods. You can monitor the working status of the on grid wind power generation system in real time through the PC or mobile phone , and you can also query the historical working status. The mobile terminal is compatible with Android and IOS. All data can be connected to the Internet of Things.


14 The solar panel control system can be added according to customer needs.


15 The controller can add various control functions such as yaw control, pitch control, mechanical folding tail control, mechanical brake, hydraulic brake, electromagnetic brake, etc. according to the type of wind turbine.
