【摘要】 随着通信技术的发展,复用保护业务被广泛应用,通信传输的质量直接影响电网运行的安全稳定。基于纵差保护同步原理,结合SDH自愈机制,文章对天津地区电力通信网络保护机制进行了深入分析,并指出现有自愈策略存在的运行缺陷,得出复用保护业务应禁用子网连接保护的结论,对未来通信网络的规划建设具有参考价值。更多还原

【Abstract】 With the development of electric communication technology,the multiplexing protection business is widely used.The quality of communication transmission directly affects the security and stability of grid operation.Based on the current differential protection synchronization method,combined with SDH(Synchronous Digital Hierarchy) self-healing mechanism,this paper analyzes the protection mechanism of electric power communication network,and introduces the defects of existing self-healing strategies,comes to a conclusion that the multiplexing protection business should disable SNCP(Sub Network Connection Protection).It has reference significance for the planning and construction of future communication network.更多还原
