Research Of Solar Energy Constant Pressure Heating Power Generation System

Under the international financial crisis and climate change, world energy beginsto enter into an unprecedented changing time. Whatever the global level or theregional levels, and whatever the developed country or the developing country,develop renewable energy sources is an important direction that all over the world’sscientific committed to. Solar energy is inexhaustible green energy, and using it is animportant way to realize energy transformation.Nowadays, the use of solar energy has been developed into many fields, such asdirect solar thermal utilization indirect using solar power and so on. Among them, thetechnology of using solar to generate power is mainly including solar photovoltaictechnology and solar thermal dynamic power technology. Solar thermal dynamicpower technology according to the difference of light-gathering power way, mainlydivided into three kinds: tower solar thermal power generation, groove solar thermalpower generation and disc type solar thermal power generation.On the basis ofreference existing solar thermal power generation technology, this paper puts forwarda new type solar thermal power generation, it is solar fixed pressure heating powersystem.This paper discusses solar fixed pressure heating power system form thefollowing facts: make sure of the basic problem of solar fixed pressure heating powersystem, including composition, structure, principle of the system; put forward adesign plan of solar fixed pressure heating power system, providing an idea forsystem’s production;based on this scheme a set of solar energy constant pressureheating power generation system model has been designed;then,finish thethermodynamic cycle theory calculation of the solar energy constant pressureheating power generation system model, and analysis the working efficiency of thissystem; to the further explore the efficiency of the power generation system,thecontrol system of this model has been designed, and by using MCGS software realizethe real-time data acquisition of the important parameters; by commissioning andtesting the model,we get the model’s experimental data,and analysising theexperimental data, discussing the drawback of the system and improving theproblems,pointing out the way to realize the conversion between solarenergy,heat,mechanical energy and electric power.Through the analysis of experiment data, this system proves the feasibility ofsolar fixed pressure heating power system and the correctness of the design idea.
