The Study And Realization Of Power Remote Monitor System

The remote monitor system is assurance of power system running safely. Its main task is monitoring the running parameters of the system in real time. Based on the data acquisition system, the realizations of the monitoring of parameters in the remote channel, including signal level, frequency, SNR(signal-to-noise-rate) of the channel, are presented respectively. The data from the data acquisition system are processed by the numerical analysis methods, such as interpolation, difference, so that the frequency of the signals transferring in the remote channel can be measured more precisely. The SNR of the remote channel can be estimated based on the frequency spectrum analysis, which leads the monitoring of the all parameters of the remote channel. The interactive communication can be realized by interconnect the monitoring subsystem with the communication networks based on the TCP/IP protocols. By this, the distributed computer networks with functions of monitoring, controlling, administrating can be realized.
