Abstract
Electric energy data acquisition system is the necessary requirement to construct "Marketing" infrastructure and smart grid, change the development mode of the company and grid. To solve the problems of the 230MHz wireless private network of the electric energy data acquisition system, such as low communication rate, fewer access points, low acquisition success rate and poor real-time performance, a new-type data transmission scheme of electric energy data acquisition system is proposed. The key technologies, such as carrier aggregation, software radio, multi-antenna, networking, OFDM, safeguard and other technologies, are discussed. The new-type communication technology based on SGWM in the electric energy data acquisition system is elaborated. The experimental results show that the field application effect of the new-type 230MHz communication key technology based on SGWM in the electric energy data acquisition system is improve the interactivity, real-time instantaneity, reliability of smart grid.. Thus it provides technical support for the popularization of the information bidirectional interaction and construction of smart grid.
