Book Description
In high voltage direct current(HVDC) systems transmission technology, a.c. power is converted(rectified) to d.c. power by means of a controlled rectifier bridge. This d.c. power is then transmitted through a d.c. link to another converter(inverter) where it is converted back to a.c. power by means of another controlled rectifier bridge. The power thyristor is the the main semiconductor element of these converter circuits. Modern interest in HVDC system technology has been on the increase since the 1950's owing to the reduced costs of transmission of d.c.(as opposed to a.c.) power for a transmission distance over 500 miles. Research in this area is generally done using an HVDC system simulated on the basis of the equivalent circuits of the converters. Also the control of the converter circuits is based on the input or output a.c. voltage waveforms. The HVDC system is simulated in the Electromagnetic Transients Program using the actual circuits of the converters. This provides the means to expose the behavior of the HVDC system under steady-state and as well as transient conditions. Furthermore, the effect of different control strategies can be verified in detail. The thesis presents the results of thyristor control entirely based on the waveform of the voltage directly across the individual thyristors rather than on the basis of idealized waveforms. The characteristics of the HVDC system which under ideal conditions can be theoretically predicted, could be confirmed by the solutions obtained from the simulations. These results have been discussed in detail. Suggestions for slight modifications necessary to make the simulation programs more comprehensive for large scale research purposes are included.

Book Description
HVDC is a critical solution to several major problems encountered when trying to maintain systemic links and quality in large-scale renewable energy environments. HDVC can resolve a number of issues, including voltage stability of AC power networks, reducing fault current, and optimal management of electric power, ensuring the technology will play an increasingly important role in the electric power industry. To address the pressing need for an up-to-date and comprehensive treatment of the subject, Kim, Sood, Jang, Lim and Lee have collaborated to produce this key text and reference. Combining classroom-tested materials from North America and Asia, HVDC Transmission compactly summarizes the latest research results, and includes the insights of experts from power systems, power electronics, and simulation backgrounds. The authors walk readers through basic theory and practical applications, while also providing the broader historical context and future development of HVDC technology. Presents case studies covering basic and advanced HVDC deployments headed by world-renowned experts Demonstrates how to design, analyze and maintain HVDC systems in the field Provides updates on new HVDC technologies, such as active power filters, PWM, VSC, and 800 KV systems Rounds out readers' understanding with chapters dedicated to the key areas of simulation and main circuit design Introduces wind power system interconnection with HVDC Arms readers with an understanding of future HVDC trends Balancing theoretical instruction with practical application, HVDC Transmission delivers comprehensive working knowledge to power utility engineers, power transmission researchers, and advanced undergraduates and postgraduates in power engineering programs. The book is also a useful reference to for engineers and students focused on closely related areas such as renewable energy and power system planning.
