The fault locators use modem to exchange data with each other remotely . in order to enable the fault locator to complete the whole procedure automatically , the author has written the communication programs 为了使测距装置能够在不需要工作人员干预的情况下完成包括双端通信在内的整个测距过程,本文作者编写了具有自动拨号/应答功能的modem通信程序
At the same time , using two - terminal voltages and currents sampled by the medium - speed sampling and processing unit synchronized by the pulse per second ( 1pps ) of gps , the fault locator can realize accurate double - ended steady - state location 同时,线路两端的测距装置利用gps的同步秒脉冲信号( 1pps )控制各自的中速采样处理单元对线路的电压、电流信号进行同步采样,用这些同步采集到的数据还可以实现精确的双端稳态法测距。
By using high - speed data acquisitioning unit designed specially to capture travelling waves of transient current , using global positioning system ( gps ) to supply high precise time tagging for both ends , using wavelet transform theories to identify the head of the travelling waves , the fault locator can realize high precise double - ended travelling waves location 该测距装置采用专门设计的高速采样单元捕获暂态电流行波信号,用全球定位系统( gps )为线路两端提供精度高达1 s的统一时标,用小波变换理论识别暂态电流行波波头信息,从而可以实现高精度的双端行波法测距( 150m ) 。
Using the high - performance digital signal processor ( dsp ) as cpu , the author designs the medium - speed sampling and processing unit of the fault locator . on the one hand , this unit can sample voltages and currents of the line synchronously ; on the other hand , this unit can start the fault locator up and select the fault lines when faults occur 本文作者还以高性能的数字信号处理器( dsp )为cpu设计了测距装置的中速采样处理单元,该处理单元一方面可以实现线路电流电压信号的同步数据采集,另一方面可以完成测距装置的故障启动和故障选线任务。
