Improved Modern Control Station for High Pressure Bypass System in Thermal Power Plant

Abstract

Thermal power plant main energy transporter is steam. In a 210 MW thermal power plant, the boiler drum pressure is 160 kg/cm2 and the temperature is 540° C. The steam is generated in the boiler drum. This steam is fed to the turbine for power generation. The turbine is converting the thermal energy in to mechanical rotational energy. Then this rotating mechanical energy is converted in to electrical energy by the Generator. When any fault occurs at anywhere in the power generation cycle, sudden load reduction is suggested for safe zone operation. In such emergency conditions and planed startup shutdown conditions the generated steam must be diverted from turbine, but the steam cycle should not disturb. There is a system called bypass system consists of High Pressure Bypass System (HPBP) and Low Pressure Bypass System (LPBP). These papers discusses about the High Pressure Bypass System and a new control station for monitoring and controlling the High Pressure Bypass Valve
