초록

본 논문에서는 화력발전소 보일러-터빈 제어시스템의 고장검출 시스템을 설계한다. 이를 위하여 보일러-터빈의 비선형 동특성을 측정 가능한 시변 파라메터를 갖는 T-S 퍼지시스템으로 나타내고 관측기 기반의 고장검출 필터를 사용하여 오차발생기를 설계한다. 고장발생 측정기를 식별하기 위하여 고장검출 필터 출구에 근사적인 역시스템을 연결하였다. 제시한 방법의 효용성을 컴퓨터 모의실험을 통하여 입증한다.

This paper deals with a fault detection system design for a boiler-turbine control system of thermal power plant. We described the nonlinear properties of the boiler-turbine dynamics as a T-S fuzzy system with time varying measurable parameters. We design a residual generator using an observer based fault detection filter. In order to identify the faulted output sensor, an approximate inverse system is connected to the outport of the fault detection filter. We demonstrate the efficiency of the suggested design method via computer simulations.
