Abstract
The availability of electricity and chilled water at a cogenerated gas district cooling plant is linked to tha availability of the gas turbines of the plant. In this study, multi-state system theory is introduced to analyze the availability of electricity which is produced by the two gas turbines each with 4.2 MW at a cogenerated gas district cooling plant. The states of the turbines and corresponding probablities are defined. The availability of electricity is estimated based on the multi-system approach using Markov chain method. The method is applied to the analysis of electricity generated by two parallel turbines. The availability of electricity is simulated based on 1400 days of historical data. The availability analysis is showed that more than 99% of electricity was available to meet the required demand of the system.
