摘　　要：针对电力系统小干扰稳定性研究存在许多不确定因素,如风力发电的间歇性、线路参数变化等影响系统稳定性的问题,笔者在已有分析此问题方法基础上,提出了一种采样方法——拉丁超立方采样,处理输入随机变量相关性。通过与随机采样的蒙特卡洛法相比,验证了该方法精度高和计算量小的优点。应用此方法对含有大规模风电场的2个算例进行分析,结果是拉丁超立方采样未做任何约束条件,输出结果能够真实地反映系统运行特性。Aiming ence of intermittent at the uncertain factors of research on small signal stability in power system, such as the influ- wind power generation and changes of line parameters on system stability, author proposes, on the basis of the existing analysis methods, the Latin Hypercube sampling and processes the correlation of input random variables. Through the comparison with Monte Carlo method, it is verified that this method enjoys the ad- vantages including high accuracy and calculation efficiency. Two examples of power systems with large - scale wind power being analyzed by this method, it is proved that Latin Hypercube sampling can reflect the real operation char- acteristics from the output result without constraints.
