Control Reconfiguration of a Boiler-Turbine Unit After Actuator Faults
Boiler-turbines are one of the most important parts in power generation plants. The safety problem in such systems has always been a special concern. This paper discusses the application of control reconfig uration by fault-hiding approach for a boiler-turbine unit. In Fault-hiding approach, after occurrence of a fault, nominal controller of the system remains unchanged; instead, a reconfigurat...
متن کاملLinear Analysis and Control of a Boiler-Turbine Unit
Boiler-turbine units are multivariable nonlinear systems. The control of such systems is not easy considering the practical tuning, implementing and maintaining problems. In this paper, the design of a linear controller for the Dalate No.4 unit is reported. Based on a nonlinear model of the unit, we analyze the nonlinearity of the unit and propose to choose the appropriate operating points so t...
متن کاملInverse Dynamic Neuro-Controller for Superheater Steam Temperature Control of a Large-Scale Ultra-Supercritical (USC) Boiler Unit
The main focus of this paper is to develop an Inverse Dynamic Neuro-Controller (IDNC) by utilizing the inverse dynamic relationship of the superheater system for a large-scale ultra-supercritical (USC) boiler unit. After a recurrent neural network-based Inverse Dynamic Process Model (IDPM) has been built and trained, it is then used as a feedforward controller to improve the superheater steam t...
متن کاملRobust Fault Detection on Boiler-turbine Unit Actuators Using Dynamic Neural Networks
Due to the important role of the boiler-turbine units in industries and electricity generation, it is important to diagnose different types of faults in different parts of boiler-turbine system. Different parts of a boiler-turbine system like the sensor or actuator or plant can be affected by various types of faults. In this paper, the effects of the occurrence of faults on the actuators are in...
متن کاملPredictive Control of a Boiler-turbine System
In this work, multiple model control of a boiler-turbine system is studied. Multiple linear local models are obtained through piecewise linearization. A bank of Kalman filters is constructed using these local models. States and model parameters used for future predictions within the predictive control are updated online through computation of probability density functions. Simulations show that...
