摘　　要：为保证变电站多跳无线网络传输的实时性和可靠性,文章首先以通信延时对网络多跳次数的限制和两条互不交叉通信路径保证传输可靠性的限制为约束条件,通过网络拓扑优化算法,确定最优的网络拓扑结构;然后基于模型预测控制的功率控制算法,保证上述优化后的网络拓扑中每个无线链接的可靠性;最后对上述算法进行仿真研究。仿真结果表明,该方法在无线通信受扰的情况下,可保证多跳无线网络数据传输的实时性和可靠性。In order to ensure the real-time and reliability of multi-hop wireless network transmission in substation,this paper first takes the restriction of network multi-hop times due to the communication delay and the restriction of two non-crossing communication paths to ensure the transmission reliability as the constraint conditions,determines the optimal network topology through network topology optimization algorithm.Then the power control algorithm based on model predictive control(MPC)ensures the reliability of each wireless link in the optimized network topology.Finally,the simulation study of the above algorithm is carried out.The simulation results show that the proposed method can guarantee the real-time and reliability of data transmission in multi-hop wireless network under the condition of wireless communication disturbance.
