主要为一个Gui演示平台，能仿真实现不同psk调制及不同状态数的STTC编码，在命令窗口输入ui_start即可进行(Gui primarily a demonstration platform, to achieve different simulation psk modulation and coding of different states of STTC in the command window can be input ui_start)

Distribution system provides a final link between the high voltage transmission system and the consumers.To improve the overall efficiency of power system, the performance of distribution system must be improved. An important method of controlling bus voltage is by shunt capacitor banks at the buses at both transmission and distribution levels along lines or substation and loads
