Tóm tắt

This paper studies the dynamic-stability improvement of a two-area four-generator system connected with a large-scale offshore wind farm based on doubly-fed induction generator (DFIG) using a generalized unified power-flow controller (GUPFC). The power flows of the studied system in steady-state conditions with and without GUPFC are calculated. A time-domain method based on nonlinear-model simulations subject to different disturbances on transmission lines and wind speed variations are both performed to examine the effectiveness of the proposed GUPFC. It can be concluded from the comparative simulation results that the proposed GUPFC demonstrates better performances for improving the dynamic stability of the studied multi-machine system as well as a large-scale offshore wind farm based on DFIG subject to various severe disturbances.
