说明：  通信信号的调制信息包含在信号的瞬时幅度、相位、频率的变化之中，不同的信号其频谱也呈现不同的特征，通过提取瞬时幅度、相位、频率以及频谱的参数统计特征，可以识别不同的通信信号。通常是利用对瞬时幅度、瞬时相位，瞬时频率和信号功率谱进行某种变换而得到可以明显区分各种信号的特征参数。(Communication signal modulation information is contained in the signal instantaneous amplitude, phase, frequency changes, the spectrum of different signals also show different characteristics, by extracting the instantaneous amplitude, phase, frequency and statistical characteristics of the parameters of the spectrum, you can identify different communication signals. Usually by the use of instantaneous amplitude, instantaneous phase, instantaneous frequency and signal power spectrum a transformation which can be clearly distinguished by the characteristic parameters of various signals.)

一1000 MW水电站（机组M1）通过一条500 kV, 700 km的输电线路与负载中心连接。负载中心模型是5000 MW的阻抗负载，由遥远的1000 MW电站和当地的5000 MW (机组 M2)电站供电。系统已经初始化，因此线路传送950 MW，接近它的潮流阻抗负载（SIL = 977 MW）。这两台机相当于一台水轮机和管理(HTG)，励磁系统和电力系统稳定器(PSS)。这三个模块位于“涡轮和调速”子系统中。通过此例，在500 kV系统中制造故障，观察PSS对系统稳定性的影响。(a 1,000 MW hydropower station (crew M1) through a 500 kV, 700 km of transmission line and load center. Load center model is 5,000 MW of load impedance. from the distant 1000 MW power station and the local 5,000 MW (Unit M2) power supply. Is initialized, it transmits 950 MW. closer to its trend of load impedance (SIL = 977 MW). This machine is equivalent to a two hydraulic turbines and Management (HTG), excitation system and the power system stabilizer (PSS). This module is located at 3 "and turbine speed" subsystem. Through this cases, the 500 kV system manufacturing fault, PSS observation of the system stability.)
