| Ensure our energy security,realize the sustainable development of economy,reduce pollution and greenhouse gas emissions of the country’s energy development strategy,through develop non-fossil energy,gradually with the fossil energy to replace fossil energy.Due to the continuing stability is poorer,wind power and photovoltaic power in the case of no stable power regulation,intermittent power supply can only ACTS as a complementary role in the power to become a reliable guarantor of electricity.By configuring the thermal storage system,thermal generator set to maintain the stability of the power load,the influence of light intensity change is small,if there is enough capacity of heat storage system,the unit can be carried out at 24 hours continuous power;At the same time,can according to the regulation related to electricity and load of power grid,quick adjustment,the output of generating unit is involved in grid primary and secondary frequency modulation;In addition,solar-thermal power generation unit start-stop than coal-fired units of short time,low minimum operation load and has better load performance.Large capacity molten salt solar-thermal power tower is an unusually large and complex system,its main by concentrated heating system,heat storage and heat exchange system and conventional power generation system composed of three parts.Because solar-thermal power stations of the selected site is quite harsh light resource requirements,so this paper intends to choose the light of the site area resources for the demonstration of the system,finally it is concluded that the region’s abundant light design suitable for the large capacity of molten salt solar-thermal power tower.Through further study of the technical features of solar-thermal power stations,finally established 100 mw of molten salt solar-thermal power tower design principles and design goals.According to the requirement of the design target,system design of field of the influence of related factors are analyzed in detail,according to the analysis results of concentrated heating system and thermal storage and heat exchange system of equipment has carried on the comprehensive optimization.Finally,in system design is completed,need for comprehensive debugging system.Under the close coordination of the various professional,finally realizes the solar-thermal power generation system of the whole operation.The fuzzy comprehensive evaluation based on AHP is carried out on the key indexes of the system’s implementation effect.The results show that the project achieves good results and can realize the whole operation of the photothermal power generation system. |
