Multi-state System Availability Model of Electricity Generation for a Cogeneration District Cooling Plant

Mohd Amin Abd Majid and Meseret Nasir

Abstract:
The availability of electricity and chilled water at a cogenerated gas district cooling plant is linked to the 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 probabilities are defined. The availability of electricity is estimated based on the multi-state system approach using Markov chain method. The method is applied to the analysis of electricity generated by of two parallel gas 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.
