Abstract

This paper presents potential performance improvements of a commercial wind farm (WF) in Taiwan by using current-limit reactors (CLRs), a static synchronous compensator (STATCOM), and a load tap changer (LTC) through computer simulations. With twenty-three 2-MW DFIG-type wind turbine generators (WTGs), this WF is connected to the 161-kV utility system through a 23/161-kV 60-MVA step-up main transformer from six feeders. Six CLRs, used to limit short-circuit currents under faulted conditions, are connected in series with the six feeders. The LTC of the main transformer is used to adjust and/or regulate the voltage magnitude at the 23-kV side. The STATCOM can provide necessary voltage support and reactive-power compensation of the studied WF. Some comparative steady-state and transient results of the commercial WF with and without the proposed CLRs, the STATCOM, and the LTC are analyzed and discussed. The simulation results show that the proposed CLRs, the STATCOM, and the LTC can effectively improve steady-state performance and transient responses of the studied commercial WF under disturbance conditions.
