The paper uses PSS/E software to study connecting an offshore wind farm with 864 MW into the 2015 Taiwan power system.Major simulation works include: steady-state flow, fault current computation, transient stability analysis and impact on critical clearing time.Three connection methods, i.e., single-point, separatepoint multi-point connection, are proposed, in which single-point is divided two voltage levels (161kV 345kV).During operation, results indicate that 345 kV method demonstrates best performance.In addition, from a partially determined by its location.In terms of stability, when grid faults take place, 161kV singlepoint appears report smallest drop as compared other scenarios.Its amplitude frequency disturbance, however, greatest all scenarios.As for time, time cases approximately times greater than required Taipower standard.Simulation this can be expected provide valuable guidelines farms systems future.
