继电保护光纤通道仿真测试及研究

Tests and studies of protection optical fiber channel simulation

随着光纤电流差动保护在电力系统中的广泛应用,实际运行中暴露出越来越多的新问题,其中由于缺乏针对光纤通道的各种误码工况的仿真测试及试验,光纤电流差动保护在通道延时、误码工况下的动作行为和动作性能没有办法进行试验和验证,针对光纤电流差动保护应用的实际情况设计出了仿真测试装置,并介绍了其实现功能、硬件设计和应用。

New problems emerges with the wide application of optical fiber current differential protection in the power system. Without the simulation tests on various bit-error conditions of optical fiber channel, the problems cannot be tested and verified including the channel time delay, operation behavior and performance on the bit-error condition in optical fiber current differential protection. This paper designs a simulation and test instrument based on the real application of the protection and introduces its functions, hardware design and application.
