The safety assessment of wind-photovoltaic hybrid power system for afforestation in desertification area

In this paper, we introduce the wind-photovoltaic hybrid power system (WPHPS) installed in Mongolia and the safety assessment for the WPHPS, which was implemented to prevent the failure mode. In order to prevent desertification and build afforestation, two groups of photovoltaic systems were installed in the Gobi desert. One of the generators, which produces 70kW of the power, operates as the power plant for cultivation in this area and another one works with wind power generator. To operate these installed systems effectively, must be implemented the safety assessment. Failure Mode and Effect Analysis (FMEA) was used as a safety assessment method in this study. The 28 of important assemblies of WPHPS were evaluated by FMEA and the results carried out 47 failure modes.
