摘　　要：为提高智能配电通信业务的服务质量,建立了面向智能配电的异构网络模型,并结合智能配电自动化系统的发展目标,分析了各类型通信业务的服务质量(quality of service,QoS)需求,进而设计了一种包括重载网络业务转移与新业务接入控制的动态负载均衡算法。算法首先根据候选网络的负载水平,以及对实时和非实时业务的QoS保证程度,将重载小区的适量业务向重叠覆盖的轻载小区转移;其次通过遗传算法获得最优业务接入方案,为不同优先级的新到业务提供有差别的服务。以某市一座35kV变电站到10kV变压器的覆盖范围为例,构建异构网络模型进行仿真,仿真结果证明了所提模型与算法的合理性和有效性,该模型为智能配电通信网络的构建和业务的调度提供参考。To improve the quality of service （QoS） of communication services in smart distribution grid （SDG）, a heterogeneous network model oriented to SDG was presented, and based on the development targets of smart distribution automation system combined with the minute analysis of QoS requirements of various types of communication services, a dynamic load balancing algorithm was proposed. Firstly, an adequate number of ongoing calls can be transferred from overload networks into the overlapping ones with light workload according to the load rate and QoS assurance degree of real time and non-real time services of each candidate networks. Then, new calls with different priorities are differently served according to call admission control strategy obtained by genetic algorithm. A heterogeneous network model was built within the coverage area from a 35 kV substation to 10 kV transformers for simulation, and the experimental results show that the model and the algorithm are effective and feasible. The proposed model can provide reference for the construction and service dispatching of smart distribution communication network.
