Abstract


With the increasing depletion of traditional energy sources , there are efforts to develop new energy sources to replace traditional energy sources . Solar energy as an emerging energy much attention . Solar energy because of its distributed widely , abundant , safe and clean , renewable characteristics become internationally recognized as the ideal new energy . Solar photovoltaic power plant more and more attention , and the future direction of development of the solar energy industry . This paper analyzes the study of the solar photovoltaic power generation system works , and residential photovoltaic power plant monitoring hardware and software design , analysis and implementation of research . Firstly, given the overall structure of the solar photovoltaic system monitoring and surveillance program , the main circuit uses a two-stage transformation structure before the level to achieve maximum power point tracking control , post- voltage outer inner current loop double closed-loop transient current inverter control ; triangle wave comparison and analysis of the working principle of the solar cell , the maximum power point tracking principle and the principle of the cloud model , using MPPT control method based on two-dimensional cloud model system maximum power point tracking control ; analysis of super capacitor energy storage principle and charge and discharge control , super capacitor as an energy storage device ; made ??a detailed analysis and discussion of the inverter circuit topology , software lock-in technique ; Finally, the TMS320F2812 chip monitor as the monitor chip , a detailed analysis of the monitor various functional modules of the monitoring system and the data acquisition circuit , drive circuit , serial communication circuit hardware design , software design and monitor .
