Abstract

In this study, risks and effects of Yazd combination cycle power plant were investigated. After identification of different parts of power plant from view point of environmental issues, different kinds of risks in utilization phases were identified and a questionnaire using Delphi method was prepared and presented to electrical industry and environment experts. In this paper, multiple-criteria decision making methods such as TOPSIS and AHP were used for analysis of environmental risks in Yazd combination cycle power plant. Therefore, after arranging risk priority using Topsis method, hierarchical structure of ENVIRONMENTAL RISK ASSESSMENT of Yazd COMBINATION CYCLE POWER-PLANT was drawn. For binary comparison of each criterion and sub-criterion, based on intensity and probability of risks’ occurrence, coupled comparative matrixes were created separately. Then through data entry to EXPERT CHOICE software criteria weight were determined using eigenvector method and hence Yazd COMBINATION CYCLE POWER-PLANT’s risk was calculated using risks ultimate weight results on the basis of intensity and occurrence probability. The results show that in different sections related to technology, biophysics and socio-economy the most important risks are conflagration and explosion, groundwater quantity, and power generation, with the weight 0.001632, 0.002574 and 0.00019 respectively. In addition decline in the region’s water table with the weight of 0.00517 is considered as the most important risk influencing on Yazd COMBINATION CYCLE POWER-PLANT. After risks identification, quantification and prioritization it comes to respond risks that identify some counter-measure features against risks before its outbreak. As a result following approaches are suggested with respect to conflagration and explosion risk in power-plant: Setting-up alerting systems such as automatic fire fighting equipments in sensitive regions, taking advantages of protection and power circuit breakers equipments and periodic inspection as well as proactive repairing-measures. Meanwhile to control water reduction level and water-tables continuous monitoring and performing training and functional plans are proposed in order to reduce water consumption and utilize more from kariz system and setting up flood control system.Hence, auditing operation was presented in order to minimum indirect and direct unwanted environmental impact of Yazd COMBINATION CYCLE POWER-PLANT and moreover some measures like environmental monitoring and management program were considered as well; the most important items included: control and prevention of noise, soil, water and air pollution resources and preventing water source depletion and non-logical water consumption.
