Abstract

A technique of the heat rate allocation was devised to monitor the performance of Combined Cycle Power Plant. This calculates the expected heat rate of current conditions and compares it with actual values. Loss allocation in heat rate is reconciled by calculating the magnitude of the deficiency contributed by major components, such as the gas turbine, heat recovery steam generator (HRSG), steam turbine and condenser. Expected power output is determined by a detailed model and correction curves of the plant.

본 논문에서는 복합화력 발전시스템을 대상으로 한 온라인 성능감시시스템에 적용될 수 있는 열소비율 손실 분담기법을 고안하였다. 이 기법은 현재 운전조건에 대한 기대 열소비율을 계산하여 이를 실제 열소비율과 비교하고 이들의 편차, 즉 손실분을 발전시스템 구성기기(가스터빈 배열회수보일러, 증기터빈, 복수기)로 분담시킴으로써 손실이 어디에서 얼마만큼 발생하는 지를 정량적으로 감지하여 조치할 수 있는 성능관리지표로서 활용된다.
