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。

For example, if a register isconnected to the data bus in an 8-bit machine. eachline of the bus connects to register.Because the databus will be an 8一bit bus, there are 8-bit Flip-flopsthat form the register, When there is information onthe data bus,and a particular register is selected toreceive data, all the Flip-flops will store data simultancously. This kind of register is refer is referred to as aparallel register.

例如，如果寄存器被联接到一台8位机的数据总线上，那么，该总线的每一条线均联接到寄存器上，因为数据总线是8位总线，所以有9个触发器来形成寄存器，当在数据总线上有信息，并且选择了一个特定的寄存器来接收数据时，那么所有的触发器将同时存储数据，这种形式的寄存器叫做&并行寄存器&。

On the hardware electric circuit, uses MAX232 torealize PC machine and between the monolithic integrated circuit leveltransformation, uses the simple 3 systems connection methodrealization correspondence, soon PC machine and the monolithicintegrated circuit transmission data end and the receive data endcross connection, two groundings direct are connected; In the softwareprogramming, on PC machine was uses the existing string mouth to debugassistant software, the monolithic integrated circuit carries on theprogramming using the assembly language.

Unlike traditional business card printing and membership card compared to making machine, although this business card printing and membership card making computers may also need to block, but because it is the way of the machine to plate, a business card printing and membership card-making machine to complete the data to the business card printing and membership card making products of this manufacturing process, saves time, materials, equipment and, in turn, reduces the cost of production.

与传统的制卡和会员卡制作机相比，虽然这种制卡和会员卡制作机也需要印版，但由于它是在机方式的直接制版，只需一台制卡和会员卡制作机就可以完成由数据到制卡和会员卡制作品的制作过程，既节省了设备、时间、材料，又降低了生产成本。
