Control system use SIEMENS PLC + TOUCH-SCREEN
Control system is comprised of PLC controller, rectifier/dumping controller and dump load. Functions of PLC: to control the generator to seek wind automatically and to stop the generating system from working automatically when it is under the following abnormal situations：over rotating speed and over temperature, as well as over wind speed etc.
Functions of rectifier/dumping controller: convert the AC power output from the generator to DC power. To make sure the whole system is safe under abnormal situations, the dump load is connected to the wind generator system. DC power converted can be either transmitted directly to the battery bank (off-grid type) or be transmitted to the grid through an on-grid inverter (on-grid type).
