With the generalized use of personal computers, microelectronic-based instrumentation and other susceptible devices, the subject of power quality and its relationship to the vulnerability of high-tech facilities is becoming an increasing concern, not only to the utility companies but also to the end-customer. In the 21st century, instrumentation and control operations require high quality and ultra-reliable power in quantities and time frames never experienced before.

Power Quality: Mitigation Technologies in a Distributed Environment presents a solid theoretical foundation of the modern mitigation technologies employed in the power quality arena, and provides an overview of the most recent challenges in this field. Readers will learn about:

• how to deal with the multifaceted characteristics of power quality studies;

• how circuit and process design can be affected by the most common power disturbances;

• the implications that electromagnetic compatibility has on the equipment and installation design;

• how power electronic devices can improve the power quality of the distribution supply; and,

• the advances in IT that can support a better power quality.

Power Quality: Mitigation Technologies in a Distributed Environment introduces the advanced concepts associated with power quality to engineers and students. It will make an excellent reference for facility electrical power engineers and maintenance technicians.

Zusammenfassung
Electrical energy is one of the main elements for the economical development of society. The just aspirations of modern societies to economical growth have forced us to secure more continual energy resources. On the other hand, climate change and international treaties aiming to reduce greenhouse gas emissions have prompted all of us to be increasingly concerned about energy efficiency and conservation. With the rapid growth of the information-based economy, widespread expansion of electronic devices has become a prevalent phenomenon in both the public and private sectors. Their suitability to perform various functions such as storage, management, processing and exchange of digital data and information, are essential support for information and communication technology (ICT). Although the consumption of energy may increase, influenced by the increase in the necessary communications infrastructure, the use of renewable energy may contribute to a more rational consumption of energy, reducing the impact on the environment. The current trend toward miniaturization in microelectronics, increased processing speed and greater functionality results in a particular sensitiveness to certain kinds of electromagnetic perturbations. Thus, this situation is not only bringing about a greater demand for electricity, but in addition higher levels of power quality and reliability (PQR) needs, in quantities and time frames that have not been experienced before.
