摘要 提出了一种系统化的方法,应用结构奇异值理论考 察发电机组参数不确定性对电力系统鲁棒稳定性的影响; 基于电力系统小扰动稳定的基本模型及其特点,分析了参 数不确定性影响传递矩阵的机理:在此基础上,给出了适 宜于μ分析的扩展模型及其推导方法,并以交轴电抗的不确 定性分析为例说明了这一过程。并指出,这种方法的一般 思想可推广用于多参数的统一检验。 This paper presents a systematic approach, usingstructured singular value theory, for checking robust stability of a power system in consideration of generator's parameter uncertainty. Based on the basic models used in power system small signal stability analysis, the mechanism of the impact of parameter on transfer matrix is analyzed. A method for derivation of an extended model that will be applied to μ-analysis is proposed. The above-mentioned process is explained by an example on the qx uncertainty. The general thoughtway of this method can be applied to multi-parameter verification.
