시뮬레이션 모델을 이용한 복합화력발전소 실시간 성능감시시스템의 개발

다국어 초록 (Multilingual Abstract)

With the advantages such as high efficiency, fast start-up and the supply of both electricity and heat, Combined Cycle Power Plant(CCPP) plays a critical role in the national energy mix. The efficiency management is critical because it uses expensive fuel while it is used for peak power management. However the efficiency management is technically difficult because its operation modes are frequently variable. Thus the limited analysis of thermal efficiency in a specific operation mode is normal practice in industries. The performance monitoring system suggested in this paper analyzes the thermal efficiency using the data obtained from field-installed sensors and ultimately supports condition-based maintenance. Furthermore, it enables 1) to validate the signals from the sensors installed on the site using physical/empirical models, 2) to detect the variation of efficiency on the basis of the expected performance using simulation rather than corrected performance using manufacture’s curves, and 3) to establish the strategies for expected electricity and heat supply on the basis of future weather conditions. Real-time thermal efficiency analysis which was not achieved by conventional technologies in the past is expected to contribute to optimize operation and maintenance. The suggestions made in this paper are the products from the joint project with Bundang CCCP of Korea South-East Power Company.
