Utilization of DFIG on an islanded power generation and distribution system

The utilization of wind generation equipment, such as DFIGs (double fed induction generators), interconnected to islanded power generation and distribution systems is investigated in order to determine their effects on the overall system operating characteristics and stability. The use of a stable power station (with high speed machines) will be critical in achieving fast and reliable transient response to network events, in particular, when large transient loads are expected on a continuous basis, i.e., industrial mining and mineral processing equipment. Simulation results of this paper assist in understanding how small power stations and wind generation equipment respond to large transients in an islanded network. In particular, detailed simulations and analyses will be presented on impacts of distributed wind generation units (1.5 MW DFIG) on the stability of a small weak network. The novelty of this paper is on detailed analyses and simulation of weak, islanded networks with interconnects DFIG´s including their impacts on system stability under various transient operating conditions.
