南方电网控制性能标准（CPS）指标存在与控制区域规模相关的特殊规律：在负荷规模相差悬殊的控制区域之间,CPS1指标的分布具有显著的差异。通过对北美CPS原理的深入分析,研究并验证了该现象的产生机理,指出由于区域控制偏差的平均波动与频率响应系数总体呈非线性正相关关系,因此CPS用于评价规模悬殊区域控制性能时存在适用性问题。引入各控制区域中短周期负荷波动平均幅值,提出了北美电力可靠性集团（NERC）标准评价规模悬殊区域控制性能的适应性调整方法。仿真结果表明,该方法消除了规模悬殊区域间CPS1指标的特殊分布现象,能够解决CPS的适用性问题。

There exists a special phenomenon of control performance standard （CPS） indicators related to load scales of control areas in China Southern Power Grid： the distribution of CPS1 indicators in control areas with great disparity in load scales is markedly different from one another. By an in-depth analysis of the principles of the North American CPS and an investigation on and confirmation of the generation mechanism of this phenomenon, it is pointed out that, beeause of the overall nonlinear positive correlation between the average fluctuation of area eontrol error （ACE） and the frequency response factor, there is the problem whether CPS is applicable to control performance assessment for areas with great disparity in load scales. An adaptability adjustment method for using the North American Electric Reliability Corporation （NERC） CPS is proposed by introducing the average amplitude of medium-short eycle load fluctuation of the controlled area. Simulation results show that this method is capable of eliminating the peculiar phenomenon of distribution of CPS1 indicators in areas with great disparity in load scales, solving the applicability problem.
