For the participation of the steam power plants in regulating the network frequency, boilers and turbines should be co-ordinately controlled in addition to the base load productions. Lack of coordinated control over boiler-turbine may lead to instability; oscillation in producing power and boiler parameters; reduction in the reliability of the unit; and inflicting thermodynamic tension on devic...

This paper describes a systematic approach to predict the water level in the drum of a steam boiler with the help of artificial neural networks (ANN). The parameters of the model can be obtained from the physical dimensions and characteristics of the boiler. The frequency of deviations and the degree of deviation of the water level in the drum can be significantly reduced by the ANN modeling of...

The optimal use of fuel energy and water in a fire tube boiler is important in achieving economical system operation, precise control system design required to achieve high speed of response with no overshot. Two artificial intelligence techniques, fuzzy control (FLC) and geneticfuzzy control (GFLC) applied to control both of the water/steam temperature and water level control loops of boiler. ...

SPIN is a tool for the simulation and veri cation of protocols. PROMELA, its source language, is a formal description technique like SDL and Estelle that is based on communicating state machines. The tool and the language are in the public domain and therefore widely used. The "SteamBoiler Control Speci cation Problem" consists of an informal speci cation of a steam boiler system in a nuclear p...

This work presents a new method for controlling fuel and air fed boiler of thermal power plant using Fuzzy logic. The control strategy is based on supervisor level using Fuzzy logic that is required to determine automatically the optimal process set points of regulations level. Besides, this paper describes thermal power plant simulator developed by Matlab-Simulink. Key-Words: Thermal power pla...

This paper presents a model predictive control (MPC) strategy based on genetic algorithm to solve the boiler–turbine control problem. First, a Takagi–Sugeno (TS) fuzzy model based on gap values is established to approximate the behavior of the boiler–turbine system, then a specially designed genetic algorithm (GA) is employed to solve the resulting constrained MPC problem. A terminal cost is ad...

In this paper a neuro-predictive method is proposed in order to control the water level in the steam drum boiler system being in use at a Power Plant of Iaşi, Romania. The steam boiler provides thermal and electrical power and it works under complex technology in order to satisfy numerous technical, security and economical requirements. A nonlinear dynamic simulator for the proposed steam drum ...
