according to the users′ actually demand for uninterruptible power supply for loads,the internal structure of digital generator is analysed and the reason for its uninterruptible function can′t be achieved.a design of the uninterrupted power supply system which transformed from the digital generator is proposed.the system uses the inverter of generators,ac through inverter for loads,at the same time,charges the battery as ac is normal.inverter the battery dc converters to ac for load,meanwhile,starting generator,when power failure.the system applies uninterruptible power for load,whether the ac is normal or abnormal,and design voltage and frequency stabilization,output zero-interrupted,battery charging and discharging management.without requiring purchase an uninterruptible power supply separately,this design can avoid duplication of investment and wasting of resources.

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.
