The Research Of Supervision System For Stand-alone Wind/Photovoltaic Generating Station

The design of stand-alone Wind/Photovoltaic generating system and the capacity matching of each components in system are always same in one area,No data can validate whether it suits this area.in fact for the load and the resource of wind and solar are different in different area.How to evaluate the actual function performance ,how to evaluate the whole system and then obtain a best optimized system are key technical issues. In order for this,the paper introduces a system of supervision and long-distance communication of stand-alone wind/photovoltaic generating system.The task established a supervision system of data collection made up of transducer, transmission,signal dispose,add on card based on 32-bit PCI Bus architecture and PC according to analyzing the whole system structure ,function mode and principle of each components. The main function of this supervision system are data collection, display,save data in database, report forms, long-distance communicationand browse etc.Finally,this paper introduces an experiment aimed at a Stand-alone Wind/Photovoltaic Generating Station for several monthes in Beijing ,then evaluates main components and anlysizes its' precision and eror...
