Relay protection method and device

The embodiment of the invention provides a relay protection method and device which relates to the field of relay protection, and can ensure the efficient transmission of power parameters to a certainextent and reduce the time delay of data transmission. The method comprises the steps that a first relay protection terminal collects the power parameters of a target loop; the first relay protectionterminal adds identification information for the power parameters to obtain the first data; and the first relay protection terminal sends the first data to a second relay protection terminal throughthe plurality of network slices. 本发明实施例提供一种继电保护方法及装置，涉及继电保护领域，能够在一定程度上保证电力参数的高效传输，降低数据传输的时延。该方法包括：第一继电保护终端采集目标回路的电力参数；第一继电保护终端为电力参数添加标识信息，得到第一数据；第一继电保护终端通过多个网络切片分别向第二继电保护终端发送第一数据。
