摘　　要：针对目前继电保护复用光纤通信方式所存在的多次光电转换降低系统可靠性的问题,提出在继保小室设置光传输设备的新通信方式构想,并对新通信方式所涉及的光通信设备抗电磁干扰问题进行了讨论和试验。通过数据分析和模拟试验论证了新通信方式的可行性。The multiple optic-electronic conversion existing in the present communication way of relay protection multiplexed with fiber-optic will reduce the system reliability. In order to resolve this problem, this paper proposes a new communication scheme of establishing optical transmission equipment in the relay protection cabinet. The anti-electromagnetic imerference characteristic of the optical transmission equipment that should be considered in the design of the new scheme is discussed based on experiments. Through the data analysis and the simulation experiment, it has been proven that the new communication scheme is feasible.
