A Research on the Communication Power Architecture and Control Method for a Hybrid Energy System

Abstract:
This paper introduces the communications power architecture and control method for a kind of hybrid energy system. The power architecture consists of the input unit, input distribution unit, power conversion unit, output distribution unit and monitoring unit. The power conversion unit includes a number of power conversion modules, and each module can connect any branch of diversified input energies to transform the input energies into electrical energy required by communications. In the control method of this paper, based on the availability of input energies as well as power supply requirements of communication base stations, and under the control of the monitoring unit and input distribution unit, branches of multiple input energies are connected to the power conversion modules working in parallel to achieve mutual backup and energy reuse. In addition, each power conversion module can switch to any branch of the same or different energy in real time and in the time-sharing manner to dynamically track the available input energy and achieve mutual backup and supplement of multiple energies.
