并用S函数编制相间距离保护和接地距离保护算法程序,构建相应的保护模块,实现了三段式距离保护。仿真结果表明,所建立的三段式距离保护模型能够正确反映在保护区内的不同类型的短路故障并发出动作信号,使断路器跳闸实现输电线路的保护功能。 (A distance protection simulation model of transmission line was established by using Simulink and SimPowerSystem toolbox inMatlab. S-function was used to programe the distance protection of phase faults and earth faults and the relevantprotectionmodelswere created to build distance protection.The simulation results show that the three-stage distance protectionmodel can respond to allkinds of faultswithin protection zones correctly and send correct signal to the breaker of the line. )

在dds中基于matlab来实现lpm_rom的编写 设置 ROM 的信息，数据宽度为 10bits，数据个数为 4096；设置 ROM为寄存器输出，不需要时钟和异步清零信号(Matlab based in dds preparation to achieve lpm_rom ROM set of information, data width 10bits, the number is 4096 data set the ROM output to register, no clock and asynchronous clear signal)

三次样条插值法用于特征分析的时候，而且可用于emd 方法中。(Cubic spline interpolation method for feature analysis, and can be used in the emd methods.)

This program is used to Simulate the performance of (n,k)Reed Solomon code in AWGN channel with plotting the results and compare with the theoretical performance of this code in AWGN channel. The program also print the SNRdB, absolute snr ,simulated probability of error, exact probability of error in each steps
