摘要:

针对电网控制普遍采用SNCP(subnetwork connection protection)自愈环保护方式所面临的问题，提出了在电力通信光纤网络中引入ASON(Automatically Switched Optical Network)智能技术。采用网状网组网方式提高网络生存能力，实现端到端业务的快速配置和部署，对网络路由进行动态的优化调整，提高网络管理的智能化水平和网络资源利用率；研究了保证自愈切换时，电网控制业务恢复算法业务传送收发路径完全一致性的通道恢复路由拆建协议，实现了电网控制业务的自动多路由保护和应对多点故障的能力。咸宁市供电公司试运行结果表明，所提算法能够有效增强通信网对电网控制业务的安全保障水平，提高全网络的生存性和可靠性。

Abstract:

In order to solve the problem of the protection mechanism SNCP (subnetwork connection protection) in power grid, this paper introduces a new technology, named ASON (Automatically Switched Optical Network) which is constructed by mesh network model, to improve the viability of the power grid. This new technology can realize the peer-to-peer business and adjust the routers dynamically. In this way, the intelligence level and resource utilization rate of the power grid network are increased. It also studies the break-before-create protocols, which keep generating the alternate routes to protect the power system and deal with multipoint failures. Commissioning results in Xianning Power Supply Company verify that the algorithm presented in this paper is effective to improve the safety level and the survivability level of the whole power system. This work is supported by National Natural Science Foundation of China (No. 50677047) and Natural Science Foundation of Hubei Province (No. 2015CFB563).
