摘　　要：传统的双回线无通道保护利用两台独立的继电器实现,接线复杂,降低了保护的整体可靠性。数字化变电站技术的发展为在一台保护设备中实现双回线无通道保护、共享两个保护对象的电气量信息提供了技术保障。研究了双回线无通道保护在一台继电器(集成保护平台)上的实现方案,描述了集成保护平台的硬件结构和双回线无通道保护的软件流程。利用继电保护测试仪波形回放功能证明了该保护方案的正确性,验证了双回线无通道保护在集成保护平台上实现的可行性。The implementation of non-communication protection of double circuit line systems based on two independent relays has disadvantages as information shareless, complex connection and lack of economic. This paper implements non-communication protection of double circuit line systems based on one relay - the integrated protection platform. Hardware structure of the integrated protection platform is discribed, and software flow of non-communication protection of double circuit line systems which is implemented on the integrated protection platform is also discribed. Large number of experiments proved that, according to various asymmetrical faults and symmetrical faults, this protecion has reliable and sensitive action performance. It is proved that the non-communication protection of double circuit line systems based on the intergrated protection platform is feasible.
