Parameric Studies on Configuration Of Power House Buildings for Coal Based Supercritical Units

Abstract

Enormous amount of energy is stored in the natural resources. Power Plant is an assembly which converts the stored energy in to mechanical and electrical energy. Power Plants of greater Power Generation Capacity are being constructed due to increasing energy demand. Design and Construction of power Plant involves huge cost. Turbine Building is one of the biggest structures of Power Plant. General Layout of the Turbine Building is similar for different projects and minor changes are made in the dimensions based on the Power generation capacity of the Plant. As large quantity of steel is consumed in this structure, if small part of it can be saved, it turns out to be quite beneficial. This report includes introduction of Main Power House Building in Power plant with comparison of the dimensions of the building used in different projects. Moreover, structural modeling of Turbine Building is done with the details of NTPC – BARH 3X660 MW project. Site Specific Response Spectrum is used for seismic analysis of the structure. Analysis of the Building is done for Vertical and Lateral loads acting on the Building. Analysis and design of the building is carried out in STAADPro. Design parameters are entered manually in the software to carry out design. Section sizes are revised based on the interaction ratio of the member and deflection limits. Template for design of members subjected to Axial compression and Bending as per IS 800:2007 is developed. Moreover, an attempt has been made to study the behavior of Turbine Building under different environmental conditions. Design for different wind and a seismic condition is carried out.
