The paper presents the faults detection and localization method using residual vectors, in order to emphasize the disturbances and faults on the outputs Ta2 and Ta3 of the steam temperature from superheaters. The control system temperature was developed under Matlab Simulink with a PI controller. Depending on the fault followed to be detected one can make(More)
In this paper one will develop the faults detection and localization method using residual vectors, in order to emphasize the noises, disturbances and faults on the outputs L<inf>1</inf> and L<inf>2</inf> of the control level plant with two coupled tanks &#x201D;Quanser Water Level Control Two Tank Module&#x201D;. The proposed method was theoretically(More)
This paper presents the design of an electronic simulator in order to reproduce the real function of the superheater in normal condition and in fault condition. With this electronic simulator there was studied the possibility to control the superheater when the perturbations action and the control of the system structure which will be implemented on the(More)
In this paper was developed a faults library for the steam boiler, the accent being on the study of the situations when faults occur in the burning process (furnace). This library is used in the monitoring and control system, the main object consisting in detection and localization of different faults. The system realise the fault detection in real time,(More)
In this paper one will develop the faults detection and isolation method using an adaptive residual generator (with one input, two outputs and two residues), in order to emphasize the noises, disturbances and faults on the outputs L<sub>1</sub> and L<sub>2</sub> of the control level plant with two coupled reservoirs &#x201C;Quanser Water Level Control Two(More)
In coal power plants from Romania, there is a major interest for the implementation of digital systems for monitoring and control, replacing the conventional control systems for power, frequency and voltage. Therefore it is necessary to develop mathematical models capable to accurately describe both dynamic and stationary behaviour of the coal burning(More)
This paper present a method to detect the transducers fault in the close loop control systems. The necessities imposed for the fault detection algorithm are: rapid answer in the case of fault, which comes out; the diminution of the risk to come out false alarms; lower effort calculation. In the paper are presented the equations of fault detection structure(More)
The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water-steam system and furnace part of the boiler. Also, the paper presents the algorithm for real time detection of model parameter variations. In this context a(More)
