SUMMARIZE

SRM on-grid controller is special matched equipment with wind turbine. It commutates the AC that generated by wind turbine to DC and then charges to storage battery groups.

1. This control system is composed by a separate controller and a separate dump load, the two unit work together to form a complete wind turbine grid control system. This control system is easy operation and simplified indication and also with full protection functions.                         
2. This control system is used to convert the three phase variable AC power from wind turbine to DC power and transport the wind turbine power to the utility power grid through grid tie inverter. 
3. Controller has built-in double over-voltage protection function: when the wind turbine voltage is exceed than maximum output voltage setting value, then the dump load will start to work,  unload the extra power to the PWM dump load, in the same time there are rated power output to inverter(Please notice, PWM dump load only unload the extra power). When the PMW dump load is breakdown, the controller will stop to work, in the same time there will no power to transmit to the grid tie inverter and the inverter also no power to transmit to the utility power system. This two over-voltage protection have a very good protection to the grid tie inverter, avoid to burn the grid inverter, and most of grid tie inverter don’t have over-voltage function.
