Power system stabilization device through transmission limit control of HVDC system linked to wind power generation

摘要

The present invention uses a permanent magnet type synchronous generator (PMSG) and a double excitation type induction generator (DFIG) to increase the HVDC transmission limit value to improve the power supply capability required by the power system, thereby improving the reliability of system operation. It relates to a power system stabilization device through the control of the transmission limit value of the HVDC system linked with. The power system stabilization device through the control of the transmission limit value of the HVDC system connected with wind power according to an embodiment of the present invention is connected to the power system, and calculates the DC power limit value using the rated capacity of a wind turbine capable of supplying fault current. And a power stabilization controller for increasing the transmission limit value of the HVDC system by applying the DC power limit value transmitted from the calculation unit as the DC limit value to the voltage dependent current command limit.
