Abstract
There are security and stability problems happened in northwest china power grid connected with jiuquan large-scale wind farms in practice, such as voltage rising and low-frequency oscillation. Analyzing data is the high load mode of Northwest Power Grid in the winter of 2012 in this paper. On this basis, simulation was implemented by using BPA simulation software to analyze the support and improvement of dynamic reactive power compensation equipment on security problems happened in jiuquan. Analysis results show that: dynamic reactive power compensation equipment has characteristics as automatic, fast regulation of reactive power. The security and stability of power grid connected with jiuquan large-scale wind farms can be enhanced effectively when these characteristics are full used.
