The invention relates to a multi-channel power network signal transmission method and system. The method comprises the following steps: acquiring data information to be transmitted; performing channel division between the sending end and the receiving end; transmitting required data information based on the divided signals; wherein the channel division comprises the following steps: respectively processing data information to be transmitted by corresponding digital frequency synthesizers and phase registers, sequentially gating all the digital frequency synthesizers by n times of clock frequency through obtained n sine waves by a data selector, and sequentially interpolating and combining sine wave amplitude data output by all the digital frequency synthesizers, and finally, a waveform with n times of system clock frequency is obtained to complete signal transmission. N is a positive integer greater than 0. 本发明涉及一种多信道电力网络信号传输方法及系统，包括以下步骤：获取待传输的数据信息；对发送端和接收端之间进行信道划分；基于划分完毕的信号传输所需的数据信息；其中，信道划分包括，待传输的数据信息分别经对应的数
