摘要
Abstract
According to the characteristics of optical fiber self-cure ring networks, a synthesis synchronization method for line differential protections is proposed. The method uses the results of ping-pong method as the primary criterion and results of reference phasor method as the auxiliary criterion. The method proposed can implement self-adaptively data synchronization with the auxiliary criterion to distinguish the working state of self-cure ring network. When the reference phasor method is used to synchronize data, the distance blocking logic is added to improve the reliability of protection. Testing results of real-time data simulator (RTDS) show that the method is easy to operate and has reliable performance.关键词
