Research And Design Of Photovoltaic Biogas Combined Power Generation System In Modern Pig Farm

In recent years,the excrement piled up in the open air at random in the large and medium-sized modern farms has become an obvious phenomenon,which has seriously polluted the environment.At the same time,large quantity of electricity used in aquaculture industry,and the traditional primary energy has appeared an unprecedented crisis since the 21 st century,in addition to its storage capacity reduce gradually,the greenhouse effect caused by the production of carbon dioxide and other gases after use.Therefore,the development and utilization of new energy is likely to become an important engine for the present and future development,the specific researches are as follow:Combining with a conventional farm in Heilongjiang,it has conducted a comprehensive analysis of its geographical location,lighting conditions,biogas technology and so on,which prove the feasibility of applying new energy and calculate the optimum parameters of angle and shadow area with the photovoltaic design software PVsyst.The main equipment of biogas power generation system was selected and the optimum technological conditions of biogas fermentation were selected through the scale of the farm.This paper describes the design of a solar-biogas combined power generation system from material selection,fixed size and installation.This system should include biogas power generation subsystems,photovoltaic power generation subsystems,solar-assisted biogas power generation subsystems,and other auxiliary subsystems.MATLAB/Simulink was used to build a photovoltaic and biogas module control system,and simulation analysis was carried out.The auxiliary temperature increasing system is designed and the energy of single heat source and double heat source is calculated.According to the environmental monitoring system,the module circuit is designed for temperature,humidity and air quality respectively.The module circuit includes single chip microcomputer,collection and processing,LED display,sensor,etc.Finally,the electric quantity is calculated and the simulation results are obtained.According to simulate the output of the whole system efficiency evaluation,put forward the annual operating costs,income and other indicators,apply calculation formulas to check the data that obtained from the simulation result of the design system.The verification results show that the solar-biogas combined power generation has significant energy-saving and emission reduction advantages over the traditional power generation models.
