Über dieses Buch

This book discusses about the new techniques of power generation control of oscillating water column (OWC) using airflow control and maximum power point tracking of OWC using rotational speed control. OWCs harness energy from the oscillation of the seawater inside a chamber or hollow caused by the action of waves. This book presents the mathematical modeling and control techniques used by OWCs. Introducing new concepts to studies of wave energy to provide fresh perspectives on energy extraction and efficiency problems, the book will be a valuable resource for researchers and industrial companies involved in thermal energy and coastal engineering. It will also be of interest to students, as it broadens their view of wave energy.

Chapter 1. Introduction
Abstract
It has become indispensable to explore clean and renewable energy resources, as carbon-dioxide emissions pose severe environmental dangers. A very troubled weather pattern and global warming issues seen in the last couple of years are proof of vulnerabilities that could get worse in the near future. Therefore, many clean and renewable energy resources such as hydro, solar and wind power are being used on a big scale to tackle these challenging circumstances.

Chapter 2. Overview of OWC Mathematical Model
Abstract
The OWC system is usually constructed on the shoreline of the ocean, as shown in Fig. 2.1 (Mishra et al. 2016d). The OWC consists of four walls. It is open at the bottom where the ocean waves hit. The OWC chamber is partly watered, while the top part of the column is filled with air. The Wells turbine is installed in a circular cabinet at the top of the chamber and is driven by a DFIG connected to it. Based on rising and falling levels of seawater, the air in the chamber is compressed and decompressed. As a consequence, the oscillatory movement of the water causes the bidirectional airflow. Notwithstanding the alternating path of the airflow, the Wells turbine is constructed in such a manner that its rotation is always one-way. Next, mathematical models of ocean waves, OWC chamber, Wells turbine and DFIG are described.

Chapter 3. Control Challenges of OWC
Abstract
The section presents the numerical simulations of the open-loop OWC plant to identify the control problems associated with OWC plants.

Chapter 4. Power Generation Control of OWC Using Airflow Control
Abstract
In this chapter, the airflow control scheme for output power control of the OWC plant is presented. The control valves are used to regulate the airflow inside the OWC chamber. Several studies have discussed the airflow control techniques in the past three decades, e.g. Falcáo and Justino (1999a), Falcáo et al. (2003, 2010a), Amundarain et al. (2010b, 2011c), Alberdi et al. (2011a, b), Mishra et al. (2015). However, the anti-windup type PID and FOPID controllers are very simple to design and very effective in terms of OWC performance. Therefore, anti-windup PID and FOPID controllers have been designed with manual as well as optimal tuning approaches.

Chapter 5. Maximum Power Point Tracking of OWC Using Rotational Speed Control
Abstract
This chapter deals with the MPPT control of OWC plant using rotational speed control. It is a very highly researched topic in OWC control. A large number of research papers have published in past three decades for rotational speed control of OWC plant.

Chapter 6. Conclusion
Abstract
In this book, modeling of the OWC plant and control schemes were discussed in detail. The simulation models of OWC plant and controllers were developed on MATLAB/SIMULINK platform. The subject matter has presented in such a way that the readers would find it easy to understand the concepts about the modeling and control of an OWC plant. A detailed account of recently developed OWC devices and their control techniques were presented in Chap. 1. The mathematical expressions for different segments of the OWC plant were discussed in Chap. 2, which include the descriptions of ocean waves, OWC chamber, Wells turbine, and DFIG. It was followed by the design of MATLAB/SIMULINK diagrams of each section of the OWC plant model.
