现在的雷达都是在多脉冲观测的基础上进行检
测的,多个脉冲积累后可以有效地提高信噪比,从
而改善雷达的检测能力。积累处理可以在包络检波
前完成,称为检波前积累或者中频积累。信号在中
频积累时要求信号间有严格的相位关系,也就是说
信号是相参的,所以也称为相参积累。此外,积累
过程可以在包络检波后完成,称为检波后积累或者
视频积累。由于信号在包络检波后失去了相位信息
而只保留了幅度信息,所以检波后积累处理就不需
要信号间有严格的相位关系,因此这种积累又称为
非相参积累。实现非相参积累的方法有很多,例如
抽头延迟线积累(FIR 积累)器和反馈积累器。

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.
