More Information
Summary:An apparatus and method of controlling an electrical generating apparatus is provided. The apparatus includes an electrical generator configured to be connected to an electrical grid and a converter comprising an inverter connected to a rotor of the electrical generator. The apparatus also includes a shunt protection circuit connected to the inverter and the rotor of the electrical generator and a control unit configured to activate and deactivate the inverter and the shunt protection circuit. The control unit is configured to, in response to determining that an abnormal condition is occurring in the electrical generator or an electrical grid to which the electrical generator is connected, deactivate the inverter and activate the shunt protection circuit. Also, after it is determined that the abnormal condition has passed, the control unit is configured to activate the inverter before deactivating the shunt protection circuit.
