Based on study of the telecontrol protocol of the power system and the Public Switching Telephone Network(PSTN) ( PSTN ), it is proposed that after appropriate modification channels for power system communication can be established by using PSTN. 通过对电力系统远动规约和公话交换网的研究,提出理论模型,即通过公话交换网建立通道,并将其用于电力系统通信通道,经过适当改进,运用于实际工程中,得到了满意的结果。
