但是在建构回归分析时，有时会发现所得到的资料是由真实解释变数和测量误差所结合而成的观测值，像这种具测量误差的回归模式，我们称为测量误差模式〈measurement error model〉。

With the development of aerial and aerospace industry, many aerial and aerospace components are needed to work in some terrific conditions (such as high temperature, high pressure, vacuum and toxic gas). For this purpose, many new materials (such as carbonylic composite material and ceramics) have been manufactured. So the study of material character in the terrific conditions, especially the precise measurement of the strain and stress, becomes very urgent.

Comparing with existing solutions, new method can utilize generators' speed signal measured by wide area measurement systems directly and detailed model and parameter of power system components were not needed. After sphering measurement-data, ICA with maximal negentropy criterion was carried out to obtain feature matrix. By this means high-dimension data of multi-machine perturbed trajectories were reduced to lower dimensions, and coherent generator groups were identified by pattern recognition consequently. Simulation results of 36-bus system with 8-generator and planning northwest China 750 kV power grid show that noise signals and bad data can be eliminated. This method is accurate in identifying coherent generator groups.

与现有方法相比，这种方法不需要获得系统元件模型和参数，而是直接球化广域测量系统(wide area measurement systems，WAMS)提供的发电机电角速度信号，再利用最大负熵准则进行独立分量分析得到特征矩阵，将高维数的多机受扰轨迹数据变换到低维空间，通过模式识别得到分群结果。8机36节点系统和西北750 kV电网规划系统算例表明，该方法能有效消除噪音和坏数据的影响，准确识别出同调机群。
