摘要
光纤保护已经成为当下电力系统的主流保护,是保证电网安全稳定运行的重要手段,光纤通道的可靠性对继电保护整体可靠性至关重要。分析了专用光纤通道和复用光纤通道的可靠性,并分别提出了可用率的计算方法。以同塔双回线路保护为例,分析了光纤通道可用率与备用芯数量的关系,同时给出了在不同备用芯数量的情况下光纤通道可用率对于纤芯可用率的灵敏度分析结果,为分析实际光纤保护通道可靠性提供了依据,也为实际工程纤芯备用数量选择提供了参考。
Optical fiber protection has become the main protection of power system and it is an important mean to ensure the safty and stability of the power grid. The reliability of fiber channel is very important to the relay protection. This paper analyzes the reliability of dedicated fiber channel and the multiplexed fiber channel. The reliability calculation methods for the two types of optical fiber channel are given respectively. Taking the optical fiber channel of double-circuit lines on the same tower as an example,the relation between the reliability of the optical fiber channel and the number of standby optical fibers is analyzed. At the same time the sensitivity analysis of the reliability of the optical fiber channels with different number of standby optical fibers is given. It provides a basis method for analyzing the reliability of the optical fiber channels for the pilot protection and also provides a reference for the selection of the number of standby optical fibers in practical projects.
