The accurate measurement of oxygen content in the flue gas at a coal-fired power plant is important for the plant operators to realize closed-loop and optimal control. In this paper, eight zirconium oxygen analyzers were used to measure the oxygen content in the flue gas under real plant conditions. A cloud model is incorporated into the measurement system. In consideration of the temporal and spatial...
This paper proposes a new method to predict wind power of wind farm using the combination of GM(1,1) model and cloud model. The original wind power signals are decomposed into high frequency part and low frequency part by wavelet decomposition. Cloud model is constructed to predict wind power of high frequency part and GM(1,1) model is used to predict wind power of low frequency part. The predicted...
The accurate measurement of oxygen content in flue gas at coal fired power plant is important for realizing closed-loop control and optimization of combustion processes. A cloud model is incorporated into the measurement of oxygen content in flue gas. A qualitative and quantitative transformation fusion model based on the cloud model theory is established. The oxygen content in flue gas from real-time...
