摘　　要：随着先进静止无功发生器(ASVG)在电力系统中的应用越来越广泛,研究其对电力系统暂态稳定的影响显得尤为重要。在详细分析了ASVG的模型和控制器后,利用基于非序贯蒙特卡罗仿真的抽样算法,从扰动的随机性和不确定性出发,来研究ASVG对电力系统暂态稳定性的影响,并以多个系统为例,进行了含ASVG的电力系统概率稳定评估。研究结果表明：ASVG的安装地点、安装个数以及网络结构等因素对系统的暂态稳定性有着重要的影响。证明了在理论计算和工程应用中,对于不同的电力网络,选择合理的ASVG安装地点、安装个数等因素的重要性。As the ASVG play more and more important rules in electric power systems, it is very important to research the transient stability of power systems with ASVG. After analyzing in detail the model and control of ASVG, the probabilistic transient stability for power systems with ASVG based on the stochastic and uncertain performance of power systems and the non-sequential Monte-Carlo sampling algorithm is built in the paper. It investigated and compared the statistical results of the different systems in detail with the different placements and numbers of ASVG. It is pointed out that the selection of the different installation place and numbers is very important for the improvement of the transient stability in different power systems.
