Exploration on the fault solving of power grid dispatching automation
针对电网调度自动化的故障解决探究

摘要

电力通信网的规模和结构日趋庞大和复杂，发生大规模故障后会导致相关电力业务中断，若不能及时修复会产生难以估量的经济损失和危险。但是，大规模的通信网故障修复工作需要大量的人力、物力和时间,修复资源不能在同一时间到达恢复现场。研究行之有效的修复策略，使电力通信网发生大规模故障后可以尽快得到相对最优修复策略，从而使受损电力业务尽快恢复通信，避免电力通信网因为无法快速得到修复而造成更严重的经济损失和危险。本文对解决网络故障恢复方法进行研究，针对如何快速、有效地恢复大规模网络故障后的电力通信网，研究单阶段和多阶段以及快速网络故障恢复方法，以期实现电力通信网大规模故障后快速、有效地恢复业务通信，安全稳定地运行。本文的主要研究内容如下:（1）大规模网络故障单阶段恢复方法。当电力通信网发生大规模故障后，由于能够及时提供的恢复资源较少，即无法立即完全修复受损的网络，也无法使所有受损的电力业务恢复通信，这种情况下需要利用有限的恢复资源有选择性地修复网络中的故障链路，使受损业务恢复通信的数量最大化。本文主要介绍的是电网调度自动化比较经常出现的故障问题，比如通讯通道误码、遥控遥调拒动等等，同时针对存在的这些故障问题进行策略分析，进而有效提升电网调度自动化的能力和水平，给电网的调度提供可靠、准确的信息数据。

Abstract

The scale and structure of the power communication network are becoming increasingly large and complex, and the large-scale failure will lead to the interruption of related power business. If not repaired in time, it will produce incalculable economic losses and dangers. However, the large-scale communication network fault repair work requires a lot of manpower, material resources and time, and the repair resources cannot arrive at the recovery site at the same time. Study the effective repair strategy, so that the relatively optimal repair strategy can be obtained as soon as possible after the large-scale failure, so that the damaged power service can resume communication as soon as possible, and avoid more serious economic losses and dangers caused by the power communication network which cannot be repaired quickly. This paper studies the network fault recovery method, for how to quickly and effectively restore large-scale network failure after power communication network, the single stage and multiple stage and fast network fault recovery method, in order to realize the power communi- cation network after large-scale fault communication, quickly and effectively operate safely and stably. The main research contents of this paper are as follows: (1) the single-stage recovery method of large-scale network failure. When power communication network large-scale failure, due to provide less recovery resources, namely cannot immediately completely repair the damaged network, also cannot make all damaged power service restore commu- nication, in this case need to use limited recovery resources to selectively repair the fault link in the network, to maximize the number of damaged business restore communication. This paper mainly introduces the power grid scheduling automation often fault problems, such as communication channel error code, remote control remote adjustment, etc., at the same time for the fault problems strategy analysis, and effectively improve the ability and level of power grid dispatching automation, power grid scheduling to provide reliable and accurate information data.
