Markov process reliability model of PV inverter

Mohamed Khalil
Abstract:
Since Photovoltaic (PV) systems have penetrated generation networks, their failures started to have a detrimental effect on the economics of power generation and risk of power interruptions. The dominant failure causes behind these failures is the Photovoltaic Inverter ( PVI). In this respect, reliability prediction of PVI has been of great concerns, nowadays, to designers and manufacturers during the design phase. In this paper, Markov process is chosen to estimate the reliability of PVI based on the recent failure data of Siemens norm SN-29500 handbook. Both the reliability and MTTF are evaluated. Results show that the estimated life span of PVI is significantly different compared with the results from similar studies based on MIL-HDBK-217F, which was last updated in 1995.
