The world's most powerful telescope for observing the universe in high-energy gamma-ray light, the observatory was originally called the Gamma-ray Large Area Telescope, but was rechristened after Italian scientist Enrico Fermi once the telescope was up and running in space.

这台世界上最强大的望远镜是通过高能伽马射线观察宇宙，最初这个天文台被称作&伽马射线广域空间望远镜&(Gamma-ray Large Area Space Telescope)，但是当这台望远镜建成后开始正常运行时，人们又根据意大利科学家恩里科·费米的名字给它重新命名。

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.
