    • In an electric power transmission network, comprising several substations interconnected by power transmission lines, a communication device of a substation communicates over a power transmission line to a communication device of a neighboring substation by using command signals in a frequency band and a guard signal located in a first half of the frequency band. For successive lines, a repeating sequence of different schemes of command signals is used, each of the schemes comprising only command signals with frequencies located in a second half of the frequency band. By using a repeating sequence of different schemes for successive lines and by using in each of the schemes only command signals with frequencies located in one half of the reserved frequency band, it is possible to reduce the number of different frequency bands required in electric power transmission networks for transmitting command signals used for coding (tele-) protection commands.
    • 在由电力传输线互连的多个变电站的电力传输网络中,变电站的通信装置通过使用频带中的指令信号和位于相邻变电站的通信装置的保护信号 频段的前半部分。 对于连续的行,使用不同方案的命令信号的重复序列,每个方案仅包括频率位于频带的后半部分的命令信号。 通过对连续的行使用不同方案的重复序列,并且通过在每个方案中使用仅具有位于预留频带的一半中的频率的命令信号,可以减少电力传输中所需的不同频带的数量 用于发送用于编码(远程)保护命令的命令信号的网络。
