Abstract

Since the average life of a wind generator is about 20 years, many of the wind systems will be employing conventional fixed-speed cage generators in spite of the superiority of the variable-speed devices. As the extent of wind integration continues to grow, the wind parks may need to be integrated with AC power grids. The integration to grids, particularly to weak ones, may give rise to transient conditions detrimental to both the asynchronous as well as synchronous systems. This article presents an integrated dynamic model of the fixed-speed wind system with a multimachine AC power system. Simulation studies of a 4-machine 12-bus system indicate that under some contingencies a small steady slip may continue to pump transients harmful for both the systems. A frequency controller in the electro-mechanical loop of the wind system has been shown to mitigate the problem effectively.
