A wind turbine converter can be equipped with a DC chopper and DC resistor to add some short-term and temporary load reserve to the system. The reserve can keep the converter operational over a rapid malfunction such as a power grid break. The DC resistor is connected to the DC chopper and together they form the temporary load reserve. The DC chopper monitors the voltage level in the DC link of the converter. When the voltage exceeds the operation limit of the chopper which means overvoltage in the DC link, the chopper connects the DC resistor to the DC link and conveys the excess energy to it. The resistor dissipates the excess energy, and the DC voltage level decreases to the normal operating level without fault trip of the converter, considering that the heat dissipation capacity of the resistor-chopper combination is sufficient. An ABRU-0x DC chopper unit includes an ABRC-65 control board and IGBT switches. In case of ACS800-77LC and ACS800-87LC converters, the customer needs to dimension and acquire an external DC resistor and its cabling separately. In case of ACS800-67LC, the factory-installed DC resistor can be included in the wind turbine converter delivery (option +D151). Each ABRU unit must be connected to a separate DC resistor. The DC chopper is equipped with fuses as standard. The fuses protect the resistor and resistor cable in a short-circuit situation.
