Development of a High Pressure Turbine Bypass System Pressure Control Model for Power Plant Simulator

Abstract

It is required that a developed control system should be verified using simulator in terms of functionality and reliability prior to application to a power plant that is a very critical facility in the industry. In this paper, the control model for turbine bypass system was developed for power plant simulator. In order to develop the control model for turbine bypass system, the tool that can be used to implement turbine bypass control logic was developed based on the turbine bypass control system manual. The developed tool was merged into the simulator development environment. The functionality of the developed tool was verified via the simulation based on the each function block specification. The HP turbine bypass pressure control logic was implemented using the developed tool and was integrated with process models and other control models such as boiler control model, turbine control model and boiler feed water pump turbine control model for 500 MW korean standard type fossil power plant. Finally, the validity of the developed control model was shown via simulation result under the integrated simulation environment.

Hardware-in-the-loop testing of bypass valve actuation system: Design and validation of a simplified real time model

“…The system architecture is heavily influenced by features and performances of the valves used to adjust pressure and temperature: useful technical information concerning valve structure and performances are available from the sites of some of the most important industrial suppliers. [7][8][9] Typical applications of bypass systems are in large fossil fired steam plants, 10 in combined gas-steam turbine power plants 1 or even in nuclear plants. 11 Hardware-in-the-loop approach…”

“…Simulation and optimization of TBSs are still the object of industrial research: Byun et al. 10 and Tsai et al., 11 for example, have recently proposed simulation tools which are dedicated to specific power plant configurations and technologies. With respect to these previous works, authors propose the idea of developing a modular, object oriented model in which every component of the simulated plant can be seen as an individual block of a library that can be used to assemble different plant layouts.…”
