Research on double-layer wireless access architecture of smart grid and its channel simulation
摘要
Abstract
The architecture of the electric power communication network and characteristics of the wireless channel are the key factors to determine the network performance. The double-layer wireless access architecture of the electric power wireless broadband private network of Southern Power Grid is studied,in which the MIMO channel performance of macrocell and conver-gence gateway directly affects the stability and operational level of the power grid. Therefore,it is particularly importance to research on the performance of MIMO channel. The typical WINNERⅡ model and Kronecker model of MIMO channel are performed with theoretical analysis and contrast simulation in the aspects of channel space correlation,channel capacity and time-domain fading. The influences of antennas quantity,signal-to-noise ratio and antennas array on channel capacity and antennas correlation are obtained with simulation results. The simulation results show that the MIMO technology can satisfy the require-ment of the system for high speed and large capacity. In comparison with the Kronecker model,the WINNERⅡ model has higher matching degree with the real propagation environment,and can be further applied in the double-layer wireless access architecture.关键词
