Based on the new cumulant matrix, a simple iterative BSS algorithm is proposed, which requires neither centering nor sphering of the data and separates the mixed signals directly.

本文定义了一种新的累积量矩阵，对这种累积量矩阵的计算实际上只需要对二阶累积量进行估计，因而相对于常规的累积量矩阵的估计，该方法计算简单，并且有可能达到较小的估计偏差。

The cartridge may have sphering mechanism which has a channel or loop with a configuration for reducing or eliminating cell settling.

这种试样盒可具有球化机构，这种球化机构具有通道或环路，这种通道或环路带有用于减少或消除细胞沉淀的构造。

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。
