| 摘要: |
| 为解决传统复杂网络理论脆弱性分析的局限性并改善网络性能，提出了一种基于业务的电力通信网络脆弱性分析方法。利用复杂网络理论构建网络模型，将业务重要度和业务流量作为网络参数，在蓄意攻击和随机攻击的策略下，以链路或节点失效所造成的业务量损失大小来描述网络的脆弱性，并找出网络中相应的脆弱部位。以电力IEEE30节点测试系统作为仿真实例，结果表明，网络业务分布越不均匀，网络脆弱性就会越高，进而网络抵御级联故障的能力就越差。而且在蓄意攻击的情况下，网络脆弱性极高。得出结论，网络业务分布越均匀，网络脆弱性就会越低。针对结论，提出了改进业务路由策略的方法以降低网络的脆弱性。仿真证明了该方法的有效性和可用性，并可为电力通信网络规划和维护提供参考，具有现实意义。 |

| Abstract: |
| In order to solve the limitation of the traditional complex network vulnerability analysis and improve the performance of the network, a vulnerability analysis method of power communication network based on the business is proposed. A power communication network model based on complex network theory is established. Business importance and business traffic are regarded as the network parameters, under the intentional and random attack strategy, the network vulnerability is measured by the loss of business when some nodes or links failed. And the corresponding vulnerable parts in the network is found. IEEE30-bus test system is used as a simulation example. The result shows that the more concentrated the distribution of business on network is, the higher the network vulnerability is and poorer the network is to withstand cascading failure. What’s more, the network vulnerability is extremely high under intentional attacks. Based on the analysis, a method which can reduce the network vulnerability by changing routing strategy is given. The simulation results show that the method is effective and usable, can provide reference for the planning and maintenance of power communication network, and has practical significance. |
