| 摘要: |
| 从统计学原理的角度研究了风电对我国互联电网CPS（Control Performance Standard）考核指标的影响机理。利用关键变量的数学期望对传统CPS计算公式进行变换，推导了用于定量分析的CPS考核指标计算公式。利用MATLAB／Simulink 建立两区域互联电网模型，仿真结果表明对CPS指标影响程度由低到高排列分别为正态分布、t分布、威布尔分布；随着风电并网容量持续增大，互联电网CPS考核指标的降低幅度也越大。 |

| Abstract: |
| The influence of wind power on the CPS（Ｃontrol Performance Standard） evaluation indexes of interconnected power grid in China is researched based on the statistical theory. The mathematical expectation of key variables is used to transform the traditional CPS formula and the CPS evaluation indexes for quantitative analysis are deduced. A two-area interconnected power grid model is built with MATLAB／Simulink and the simulative results show that，the influence of wind power distribution on CPS index increases from normal distribution，t distribution to Weibull distribution；the bigger the interconnected power grid capacity becomes，the larger its CPS evaluation index drops. |
