Energy Audit of thermal power plant ACBIL (Korba)

Abstract

The world is facing the challenge of global warming and environment protection. On the other hand, the demand of electricity is growing fast due to economic growth and increase in population. With the consideration of environmental issues and sustainable development in energy, ideally, renewable energy such as wind, solar, and tidal wave should be only resources to be explored. Since the growth in demand is also a heavy factor in energy equations, then the renewable energy alone is not able to generate enough electricity to fill the gap within a short time of period. Power plants are one of the most suitable choices for environmental enhancement and higher efficiency. However, there has been an issue of whether or not to adopt this technology in the INDIA because it is not clear whether the dynamic response and performance for plants can satisfy the Gird Code requirement. This thesis reports a study of dynamic responses of power plants through mathematical identification. It also presents a new control strategy based on an alternative configuration of generalized predictive control for enhancement of the plant responses. The model has also been verified for certain operation conditions with the different sets of data obtained from 135MW power plant. Therefore improving energy efficiency is the main focus of Energy Auditing. Experiments are carried out to validate the results, obtained by the Energy Auditing at ACBIL Thermal Power Station in Unit 135MW which has maximum power generated capacity of about 330MW.
