摘要
根据牵引变电所继电保护系统的实际情况和测试要求,提出了一种利用工控机和PLC相结合的新设计方案,实现了继电器单体和整组的自动测试功能。详细地介绍了测试系统的软硬件设计,智能逻辑转换单元的构成,以及测试功能的实现过程。
According to the actual situation and test rules of traction substation,a new design scheme is proposed, and industrial computer is combined with PLC to realize the automatic test of single-relay and linkage. The design of the hardware and software of the testing system, the composing of intelligent logic conversion unit and the realization of system function are detailedly introduced.
