Study on Risk Assessment for Lightning Hazard of Grid-connected Photovoltaic Power System
Hui Feng · Science Technology and Engineering · 2014
According to large areas of open-pit power generation regions,intensive confluence lines and highly sensitive control,countercurrent equipment,by means of the existing theory and standard of risk assessment for lightning hazard,the method of risk assessment is put forward for lightning hazard of grid-connected photovoltaic power system scientific and feasible on the basis of further researching damage source,damage type and influencing factors of damage degree. In the assessment,according to the problem of grid-connected photovoltaic power system determination of the collection area overlap in different areas and the ambiguity of direct stroke protection level,the quantitative solving methods by the plotting method based on electro-geometrical model is given.
