配电网智能化是提高供电可靠性和供电质量的重要手段,对配电网状态进行实时监测是实现配电网智能化的重要基础。无线传感器网络以其独有的组网灵活性、可扩展性和自组织自恢复能力,在智能配电网通信中得到了广泛关注。路由算法是无线传感器网络的网络层关键技术,算法应从整个网络系统角度,考虑网络能量的均衡使用,最终延长网络寿命。而传统的无线传感器网络因节点受能耗及路由算法限制,网络寿命较短。研究配电网应用场景下的能耗均衡路由算法成为无线传感器网络应用的一个关键问题。文中提出一种面向城市配电网的延长网络寿命的路由算法,能够平衡网络节点能量消耗,进而延长网络寿命。仿真结果表明,提出的方法能够有效延长网络寿命,适合在配电网通信中使用。
Intelligent distribution network is to improve the power supply reliability and power quality of an important means of real-time monitoring of distribution network status is to achieve an important basis for distribution network intelligence. Due to its unique networking flexibility, scalability and self-organizing self-recovery capability, wireless sensor networks have drawn extensive attention in smart distribution network communications. Routing algorithm is the key technology in wireless sensor network. The algorithm should consider the balanced use of network energy from the perspective of the whole network system and finally extend the network lifetime. The traditional wireless sensor networks due to node energy consumption and routing algorithms limit the network life is shorter. It is a key issue to study the energy consumption equalization routing algorithm under the scenario of distribution network as a wireless sensor network. This paper presents a routing algorithm for city distribution network to extend network life, which can balance the energy consumption of network nodes, and then extend the network life. Simulation results show that the proposed method can effectively prolong the network life and is suitable for distribution network communication.
