Join With us. Today Updates. Statics and Dynamics By R. The reason for using capital C is to distinguish Controllers from the controllers used for industrial controls.
Besides, the word "device" sounds like a component, and the authors request the readers to use the word Controller for FACTS Controllers. The authors' intent in writing this book on FACTS is to provide useful information for the application engineers rather than for a detailed post-graduate college course. Therefore, there is an emphasis on physical explanations of the principles involved, and not on the mathematically supported theory of the many design aspects of the equipment.
Nevertheless, post-graduate students will also greatly benefit from this book before they launch into the theoretical aspect of their research. This book will help post-graduate students acquire a broad understanding of the subject and a practical perspective enabling them to use their talents on real problems that need solutions. The book does not go into the details of transmission design and system analysis, on which there are already several good published books.
Engineers who wish to acquire sufficient knowledge to sort out various options, participate in equipment specifications, and become involved with detailed engineering and design will find significant value in reading the entire book in preparation for more lifelong learning in this area.
Chapter 2: "Power Semiconductor Devices" is a complex subject, and the subject matter of many books. In this book, sufficient material is provided for the FACTS application engineer for knowing those options.
Those familiar with the subject of HVDC know that practically all the HYDC projects are based on use of thyristors with no gate tum-off capability, assembled into pulse converters, which can be controlled to function as a voltage-controlled rectifier ae to de or as inverter de to ac. The voltage can be controlled from maximum positive to maximum negative, with the current flowing in the same direction; that is, power flow reverses with reversal of voltage and unidirectional current.
Current-sourced converters based on thyristors with no gate turn-off capability only consume but cannot supply reactive power, whereas the voltage-sourced converters with gate turn-off thyristors can supply reactive power.
Such converters are based on devices with gate turn-off capability. In such unidirectional-voltage converters, the power reversal involves reversal of Preface current and not the voltage. The voltage-sourced converters are described in Chapter 3 and the current-sourced converters in Chapter 4. There are a wide variety of FACfS Controllers, and they have overlapping and competing attributes in enhancing the controllability and transfer capability of transmission.
The best choice of a Controller for a given need is the function of the benefit-to-cost consideration. Chapter 8 describes the combined series and shunt controllers, which are in a way the ultimate controllers that can control the voltage, the active power flow, and the reactive power flow. There already is a large volume of published literature.
At the end of each chapter, authors have listed those references that represent the basis for the material in that chapter, as well as a few other references that are directly relevant to that chapter. Narain G. This support also was vital for Dr.

Kalyan Sen, who performed some computations and simulations for the book. Gyugyi wishes also to express his thanks to the executives of the Westinghouse Electric Corporation, who supported and funded the FACfS technology development, and to Siemens Power Transmission and Distribution who, having acquired Westinghouse FACfS and Custom Power business, continue to embrace the technology and pursue its application to utility systems.
A particular debt of gratitude is extended to John P. Special credit is due to the pioneering utilities who are at the forefront of exploiting advanced technologies and maintaining high-level technical and management expertise to undertake first-of-a-kind projects. Arslan Erinmez, of the National Grid Company, England, and their colleagues, and for their pioneering work in the large scale application of Static Var Compensators.
They played a significant role in making those two utilities the largest users of SVCs, each with over a dozen installations. Under the chairmanship of Dr. Hingorani, and now Dr. In addition, the authors acknowledge Dr. Arslan Erinmez, Dr. Pierre-Guy Therond, Dr. Adel Hammad, Dennis Woodford, and Michael Baker for generating important source material to the author's knowledge base. Special acknowledgment is due to Professor Willis Long for orchestrating material and a diverse faculty for an excellent course on FACfS for professional development at the University of Wisconsin.
Hingorani further acknowledges Dr. Vic Temple for reviewing the chapter on power semiconductor devices, and his son Naren for his editorial help. It would make a long list for the authors to acknowledge their professional colleagues working worldwide, who are among the leading innovators and contributors to the transmission and power electronics technologies.
This is done for economic reasons, to reduce the cost of electricity and to improve reliability of power supply. Transmission interconnections enable taking advantage of diversity of loads, availability of sources, and fuel price in order to supply electricity to the loads at minimum cost with a required reliability.
In general, if a power delivery system was made up of radial lines from individual. With that perspective, transmission is often an alternative to a new generation resource.
Less transmission capability means that more generation resources would be required regardless of whether the system is made up of large or small power plants. In fact small distributed generation becomes more economically viable if there is a backbone of a transmission grid.
The cost of transmission lines and losses, as well as difficulties encountered in building new transmission lines, would often limit the available transmission capacity.
It seems that there are many cases where economic energy or reserve sharing is constrained by transmission capacity, and the situation is not getting any better. In a deregulated electric service environment, an effective electric grid is vital to the competitive environment of reliable electric service. It may lead to large power flows with inadequate control, excessive reactive power in various parts of the system, large dynamic swings between different parts of the system and bottlenecks, and thus the full potential of transmission interconnections cannot be utilized.
The power systems of today, by and large, are mechanically controlled. There is a widespread use of microelectronics, computers and high-speed communications for control and protection of present transmission systems; however, when operating signals are sent to the power circuits, where the final power control action is taken, the switching devices are mechanical and there is little high-speed control.
Another problem with mechanical devices is that control cannot be initiated frequently, because these mechanical devices tend to wear out very quickly compared to static devices. In effect, from the point of view of both dynamic and steady-state operation, the system is really uncontrolled. Power system planners, operators, and engineers have learned to live with this limitation by using a variety of ingenious techniques to make the system work effectively, but at a price of providing greater operating margins and redundancies.
These represent an asset that can be effectively utilized with prudent use of FACfS technology on a selective, as needed basis. In recent years, greater demands have been placed on the transmission network, and these demands will continue to increase because of the increasing number of nonutility generators and heightened competition among utilities themselves.
Added to this is the problem that it is very difficult to acquire new rights of way. Increased demands on transmission, absence of long-term planning, and the need to provide open access to generating companies and customers, all together have created tendencies toward less security and reduced quality of supply. The FACfS technology is essential to alleviate some but not all of these difficulties by enabling utilities to get the most service from their transmission facilities and enhance grid reliability.
It must be stressed, however, that for many of the capacity expansion needs, building of new lines or upgrading current and voltage capability of existing lines and corridors will be necessary. The possibility that current through a line can be controlled at a reasonable cost enables a large potential of increasing the capacity of existing lines with larger conductors, and use of one of the FACfS Controllers to enable corresponding power to flow through such lines under normal and contingency conditions.
These opportunities arise through the ability of FACfS Controllers to control the interrelated parameters that govern the operation of transmission systems including series impedance, shunt impedance, current, voltage, phase angle, and the damping of oscillations at various frequencies below the rated frequency. These constraints cannot be overcome, while maintaining the required system reliability, by mechanical means without lowering the useable transmission capacity.
By providing added flexibility, FACfS Controllers can enable a line to carry power closer to its thermal rating.Farzaneh has taught more than undergraduate and graduate course sessions in electric power engineering.
