摘要:

高比例新能源、交直流特高压远距离输电、高比例电力电子的应用给现有技术带来挑战的同时,也对电力通信网的调度运行管理提出了更高的要求。电网与电力通信网是典型的相依网络,通信网发生故障,特别是高重要度节点故障,不仅对通信自身网络系统造成严重影响,还会影响其相依网络,引发连锁故障。为此,首先总结通信网与电网业务耦合分析面临的挑战,然后提出判决通信网故障检修对电网业务影响的分析模型,以及受影响业务恢复模型,开发形成一种耦合电网安全的通信网与电网协同辅助平台,实现N-X及多维度故障检修场景下的自动化分析计算。最后以某区域骨干光缆网架和传输系统为实际场景进行验证,达到预期效果,有效提升了极端场景下通信网快速响应能力。

Abstract:

The application of high proportion new energy, AC/DC ultra-high voltage long-distance transmission, and high proportion power electronics has brought not only new challenges, but also higher requirements for the scheduling and operation management of power communication networks. The power grid and power communication network are typical interdependent networks. Faults of communication network, the highly important nodes in particular, have a serious impact only only on the communication network system itself, but also on its dependent networks, and may lead to cascading failures. Firstly, the challenges of coupling analysis between communication network and power grid business were summarized. Then, an analysis model for judging the impact of communication network fault maintenance on power grid business and a recovery model for the affected business were proposed, and a assisted decision-making platform coupling communication network with power grid for power grid security was developed, thereby realizing the automatic analysis and calculation under N-X and multi-dimensional troubleshooting scenarios. Finally, validation was conducted using a regional backbone transmission network as a practical scenario, achieving the expected results and effectively improving the rapid response capability of communication networks in extreme scenarios.
