Abstract：Distributed photovoltaic(PV)power generation,as a novel electricity generation and comprehensive energy utilization model with a promising development prospect,exhibits significant differences from tradition-al centralized power generation systems such as thermal power plants.In order to solve the problems such as lengthy power distribution lines and voltage fluctuations due to high voltage levels in traditional power genera-tion,Luotuoshan Coal Preparation Plant operates by following of"local generation,grid connection,conversion,and utilization"and the strategy of power generation for own use.The constructed distributed PV system con-sists of the following components:555 Wp high-efficiency monocrystalline silicon half-cell PV modules,string inverters with maximum power point tracking(MPPT)functionality,ac combiner boxes,and lightning protec-tion devices.What is focused is the development of a digital management platform,and the wireless transmis-sion technology that relies on the G2-4G-ST data acquisition modules to achieve remote monitoring through 4G communication.The use of the high-efficiency monocrystalline silicon photovoltaic modules as well as the BOOST step-up chopper and DC-AC technology and string inverters for improving overall practice shows that the distributed photovoltaic power generation system not only helps to stably provide the power generated by a system of the same scale,but also effectively solves the problem of power loss during the process of boosting and long-distance transmission.In addition,this power generation mode has the advantages of no noise,no light pollution,and no radiation,meeting the requirements of static power generation with zero emissions and zero pollution,and has nowadays become one of the main renewable resource utilization methods.Distributed photo-voltaic power generation mode has significant advantages and importance in the energy field,and has certain ap-plication value for promoting the development of green energy in coal washing plants,reducing environmental pollution,and improving the sustainable development of enterprises.
