Transient stability analysis of Taiwan Power System's power grid connected with a high-capacity offshore wind farm

The transient-response simulation results of Taiwan Power System whose power grid is connected with a high-capacity offshore wind farm (OWF) of 100 MW subject to symmetrical and unsymmetrical severe disturbances using a commercial power-system simulation software are presented in this paper. A three-phase short-circuit fault is suddenly applied to the collector bus and power grid of the studied power system to compare the transient power fluctuations of the wind-turbine generators (WTGs) with and without protective relays, which are connected at different locations through infield submarine cables. The simulated transient results obtained in this paper can offer future operational references for grid-connected WTGs located at different OWFs with various capacities.
