발전유형별 냉각수 배수시스템의 경제성 분석

Abstract

In this study, the purpose of this study is to analyze the economic feasibility of cooling water discharge systems for each type of power generation while proposing a new method of economical analysis using the case of fishery loss compensation. Prior to the economic analysis of this study, the correlation between the data was confirmed through correlation analysis and regression analysis between the case of fishery loss compensation, generation capacity, and cooling water discharge. The economic analysis of this study was defined as comparing and analyzing the degree of compensation for fishing losses required to produce 1MW, which is the cost/benefit ratio, by classifying the cost part into the fishery loss compensation and the benefit part by power generation capacity. The results obtained in this study are summarized as follows. As a result of correlation analysis and regression analysis, correlation between fishery loss compensation, power generation capacity and cooling water discharge was confirmed. As a result of economic analysis in terms of compensation for fishery losses in this study, it was analyzed that underwater discharge was more economical than surface discharge by cooling water discharge system. In addition, by type of power generation, it was analyzed that there was economic feasibility in terms of compensation for fishery losses in the order of combined cycle power, thermal power, and nuclear power generation, and the combined power was analyzed to have higher economic efficiency than other power generations. Finally, the results of this study are expected to be used as basic and proof data to support the results of various domestic and international studies on underwater discharge systems.
