©　2013　IEEE.　An　electric　power　dedicated　broadband　wireless　network　traffic　load　capacity　test　and　evaluation　method　is　designed,　which　will　be　used　for　the　performance　test　and　evaluation　of　grid　wireless　communication　network.　This　method　can　be　used　in　the　actual　broadband　wireless　communication　network,　to　count　and　analyze　the　data　goodhput,　delay,　packet　loss　rate,　and　retransmission　rate　performance　of　power　business　in　the　broadband　wireless　communication　network.　The　capacity　performance　of　broadband　wireless　communication　system　can　be　evaluated,　then　it　can　judge　whether　the　wireless　communication　system　can　meet　the　requirements　of　power　business　data　communications.
