Steam Turbine Steam System

Features of New Steam Turbine Control System

OVERVIEW: Along with advances in system component technologies, modern state-of-the-art power plant control systems are being developed by incorporating such advanced technologies as extensive digitization of high-speed control circuits, interconnection with other equipment over open interfaces, and a repertory of diverse multiplexed systems. Based on Hitachi Integrated Autonomic Control System...

Simulation of Control of Multi-variable Control Loop: Steam Turbine

Abstract The paper deals with the description and simulation verification of one of possible methods to control of multivariable control loops. In this case, the so called main controllers, binding members and correction members are used. The proposed method of control combines classical way to ensure of autonomy of control loop via binding members and the use of the method of single-variable b...

Steam Turbine Configuration

Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rota...

Steam turbine model

In order to characterize the transient dynamics of steam turbines subsections, in this paper, nonlinear mathematical models are first developed based on the energy balance, thermodynamic principles and semi-empirical equations. Then, the related parameters of developed models are either determined by empirical relations or they are adjusted by applying genetic algorithms (GA) based on experimen...
