Experience shows that semiconductor switches in power electronics systems are the most vulnerable components. One of the most common ways to solve this reliability challenge is componentlevel redundant design. There are four possible configurations for the redundant design in component-level. This paper presents a comparative reliability analysis between different componentlevel redundant designs for solid state fault current limiter (SSFCL). The aim of the proposed analysis is to determine the more reliable component-level redundant configuration. The mean time to failure (MTTF) is used as the reliability parameter. Considering both fault types (open circuit and short circuit), the MTTFs of different configurations are calculated. It is demonstrated that more reliable configuration depends on the junction temperature of the semiconductor switches in the steady state. That junction temperature is a function of i) ambient temperature, ii) power loss of the semiconductor switch and iii) thermal resistance of heat sink. Also, results' sensitivity to each parameter is investigated. The results show that in different conditions, various configurations have higher reliability. The experimental results are presented to clarify the theory and feasibility of the proposed approaches. At last, levelized costs of different configurations are analyzed for a fair comparison.

“…The validation of a lifetime extension achieved with lifetime control is another field of interest. Early research calculated the mean time between failures (MTBF) or the failures in time (FIT) to evaluate the lifetime of a product [53]. But since the validity of theses parameters is limited, current research shifts to Weibull statistics and the mean cumulative function (MCF) [54], [55].…”

Small wind power systems (SWPSs) of 100kW or below are critical in addressing increasing global energy consumption and pressing greenhouse gas emission issues. Energy cost, i.e. cost of generating one kWh or MWh of electricity is an important consideration for design, development and operation of SWPSs. Various methods for energy cost estimation have been reported, but they typically consider only some aspects of the wind power systems. This paper presents a novel energy cost evaluation methodology for SWPSs, integrating wind turbine energy production, system component efficiency, cost, and reliability together into a single comprehensive model. Monte-Carlo simulation is applied to produce random functional intervals or failure intervals, taking into account the statistical nature of reliability. As compared with previous methods with segregated and deterministic approaches, the new method comprehensively analyzes the energy costs of SWPSs through an integrated and stochastic approach. The proposed methodology is applied to studies of various SWPS configurations at a typical 30kW level for both fixed-speed and variable-speed operations. The simulation results present an overview of the investment required for an SWPS over its installed lifetime, reveal cost effectiveness of different configuration options, and provide a benchmark for energy cost evaluation of wind power systems.
