Title Research on Recognition Method of Photovoltaic Electricity Stealing By Raising Voltage                                                   
Abstract
With the development and change of global energy structure,the popularity of clean energy is constantly raising.In recent years,the rapid development of the photovoltaic industry and national strategic support has increased the installed capacity of photovoltaic power generation possible. However,the stealing cheating action that followed will continue to affect the normal development of the photovoltaic industry.The recognition technology of photovoltaic electricity stealing by raising voltage is the focus of the research,in this paper, the electricity stealing principle,the equivalent circuit modeling methods and characteristics under different conditions are analyzed,thus put forward the measures to identify. 源`自*六)维[论*文'网www.lwfree.cn
Firstly,this paper analyzes the domestic and international photovoltaic technology,Secondly,the thesis analyzes types of general electricity stealing and photovoltaic grid-connected power generation electricity stealing.Finally,the analysis of the principle and simulation of electricity-stealing mode, and the simulation debugging on the model has been carried on; according to the characteristics of power supplied by grid and photovoltaic under different environmental parameters before and after the electricity-stealing,the method is proposed and verificated by simulation .
