Overview

Modelling and Control of Organic Rankine Cycle Based Waste Heat Recovery Systems is a systematic study of modeling and control of ORC-based systems for waste heat recovery, bringing together rapidly developing research in this area. The organic Rankine cycle (ORC) is now commonly accepted as a viable technology to convert low grade heat in the thermal power plant, the diesel engine and the fuel cell. In response to limited reserves, increases in cost and the environmental impact of fossil fuels, the cumulative global capacity of ORC power systems for the conversion of renewable and waste thermal energy is undergoing rapid growth. Recovery utilization for low-grade heat energy has become one of the important energy-saving methods. In addition, technological advancements and cost reduction allow for competitive organic Rankine cycle machines on the market. Chapter 1 introduces the current status of organic Rankine cycle systems and reviews advances and challenges in organic Rankine cycle (ORC) systems modeling and control strategies. Chapter 2 presents the configuration of ORC power systems, analyzes the performance of ORC systems and summarizes their features, including both the operating modes and control objectives of ORC systems. Chapter 3 establishes the physical model for ORC power systems after building basic component models (evaporator, condenser, expander, receiver and pump). The model of an ORC power system is identified using input/output data. Chapter 4 designs controllers for ORC power systems operating on both, following electric power mode and waste heat mode respectively, using optimized set-points of controlled ORC power systems. Chapter 5 focuses on using simulation tools for building development systems that experimentally validate the physical model and control strategies of ORC power systems. Engineers and professionals, as well as recent graduates in the power generation industry will find this a valuable reference.
