在智能电网中,如何有效降低电力通信安全风险成为电力系统亟需解决的问题之一.而业务路由是影响通信风险的重要决定因素,但是现有的路由算法中没有考虑电力通信业务的特殊性,会引起通道段中业务分布不均衡,进一步导致通道段和网络的整体风险增大.为此,该文提出面向业务的风险均衡路由分配机制来降低通道段和网络整体风险.首先,该机制综合业务重要度和通道可用性等因素,建立了面向业务的风险均衡问题模型.其次,基于该模型提出一个面向业务的路由风险均衡机制.最后,通过基于某省电力通信网拓扑数据进行仿真,相对于传统的可用性路由(ARR)和负载均衡(LB)算法,该文所提机制能将业务通道风险均衡度提高30%以上,并将网络总体风险度降低至少6%,具有很强的现实意义.

In the smart grid, risk of power communication has become the problem of power system needs to solve, the service route is an important factor of communication risk. However, existing routing algorithm does not take into account the special nature of power communication services, it could cause unbalanced distribution of service link, and further lead to increased risk of the overall network. Therefore, a risk balance based service route allocation mechanism is proposed to reduce the risk of communication circuit and the overall risk of network. First, service important degree, link availability and other factors are integrated to establish a business-oriented risk balance model. Secondly, a business-oriented route risk balance mechanism is proposed based on this model. Simulation based on the province electric power communication network topology data, compared with the Availability-Aware Routing (AAR) and Load Balancing (LB) algorithms, the proposed mechanism can improve the service link risk balance degree more than 30%, and overall network risk is reduced by at least 6%, which has a very strong practical significance.
