This paper presents a methodology for modeling and calculating the reliability and availability of low power portable direct methanol fuel cells (DMFCs). System reliability and availability are critical factors for improving market acceptance and for determining the competitiveness of the low power DMFC. Two techniques have been used for analyzing the system reliability and availability requirements...
This paper is to derive the optimal planning of protective relay schemes for a transmission network by immune algorithm. The historical data of protective relay malfunction in Taipower has been used to determine the failure rate and repair rate of each type of protective relays in Taipower system. The Markov models of protective relays are determined and integrated with the transmission network to...
Fuel cell (FC) power plants are subject to a number of possible outage and derated states due to partial or full failure of auxiliaries. Furthermore, most of the power system reliability studies reported in the literature assume mean values of the particular measure of reliability. However, the reliability indices for grids such as failure rate, outage duration, etc. vary for different time period...
