POWER OSCILLATION DAMPING BY A CONVERTER-BASED POWER GENERATION DEVICE

摘要

There is provided a power generation park (100) comprising a power output (108) for providing electrical output power (150) to an electricity network (128). A power generation device (102a,... 102n) comprises a converter device (106) configured for receiving input power (142) from a power generator (104) and providing, in response hereto, the electrical output power (150) to the power output (112). The power generation park (100) further comprises a controller (122) being configured for receiving an oscillation indicating signal (126) indicative of a power oscillation in the electricity network (108), the controller (122) being further configured for providing a damping control signal (132) in response to the oscillation indicating signal (126); the converter device (106) being configured for modulating the electrical output power (150) in response to the damping control signal (132)so as to damp the power oscillation in the electricity network (128).
