Preface to the English Version

In modern society, electricity has a profound impact on the development of human livelihood and production, as well as economic and social development. All equipment and devices, from the locomotive driving devices to mobile phones, from electric lights to factory machinery, are required to be powered by electricity. It's the responsibility of us as electrical engineers to ensure a safe and reliable power supply and make electricity available everywhere so that everyone can enjoy sustainable and affordable power supplies. To ensure power supply is not only a technical issue, but is also an economic one. In addition, it has a close relationship with resources and the environment, and has to rely on scientific and technological innovation. From Faraday's discovery of electromagnetic induction to Edison's invention of electric light, technological innovation has made the history of power industry and promoted the innovation and development of the world.

Power grid is the basic platform for ensuring power supply. With the growth in demand for electricity and advances in electric power technology, the world's power grids have evolved from initial single‐machine and single‐line systems to small town grids, urban grids, provincial grids, national grids, and continental grids. With increasing grid scale and strengthened grid functions, large‐scale grid interconnection has become the trend. Innovation is the most important driving force for the development of power grids. Thanks to the development of high voltage and ultra‐high voltage transmission technology, and the application of AC and DC transmission technology, power grids are more closely interconnected with each other and the power supply is becoming far more safe and reliable.

The variable frequency transformer (VFT) is a new type of grid interconnection device. By integrating technologies of power transformer, phase shifter, hydro generator, doubly fed generator, DC drive, and other technologies, and with functions such as smooth adjustment of transmission power, suppression of low frequency oscillation, and adjusting system frequency function, it can realize the interconnection of asynchronous power grids, supplying power to weak power systems and passive systems, and providing black‐start power. VFT is an important achievement of power technology innovation in the new century. It provides a new option for the interconnection of large power grids, has been widely applied in North America, and has achieved good results.

As an engineer who has been long engaged in research on new power technologies, I specialize in power system simulation, overvoltage and insulation coordination, flexible AC transmission technology, UHV power grids, smart grids, Global Energy Interconnection, new energy sources, and technical standards. I have undertaken major research projects such as China's first 500 kV compact line, the first thyristor controlled series compensation project, and the first UHV AC and UHV DC transmission project. VFT is the main research content of my doctoral dissertation. Learning from the VFT‐related articles published by GE and based on years of research and practice in power systems, I have profoundly studied the work principle, mathematical models, simulation methods, and control systems of VFTs and solved problems of digital simulation analysis tools, operation control strategy, and large system low‐frequency oscillation in the VFT. In addition, I have analyzed and verified the operational characteristics of the VFT in power systems and its good performance. Through in‐depth study, I firmly believe that VFT will be a promising development and have prospective application in the power system as a new interconnection technology.

Funded by the electrical power scientific work publication program of the State Grid Corporation of China (hereinafter referred to as SGCC), the Chinese version of Large Electric Power System Grid Connection New Technology – Theory and Application of Variable Frequency Transformers was finally published and released by the China Electric Power Press in 2013, receiving positive responses from the industry. In 2014, Wiley organized experts to study the book and decided to publish the book in English in order to promote the application of this new technology to the world. The publication and release of this book as the world's first English monograph on the VFT reflects the forward‐looking awareness and innovation spirit of Wiley. In order to enrich the research content of variable frequency transformer and respond to Wiley's requirements, the author has added 40% extra content to the book based on the new development of UHV power grid, smart grid, and Global Energy Interconnection. I would say that the English monograph is more than just a translation of the Chinese version, as it has richer content.

Through the joint efforts of all parties, the English version of Variable Frequency Transformers for Large Scale Power Systems Interconnection: Theory and Applications has finally been published and released. As the world's first monograph that systematically studies and introduces VFT, it has won the concern and support of a lot of experts and friends. Wiley, the China Electric Power Press, and Mr. R.J. Piwko from GE, Mr. Wang Qiankun from GEIDCO, Mr. He Wei from China Jibei Electric Power Company LTD. have given me a lot of support and help. I would like to take this opportunity to express my heartfelt thanks to all my peers and friends who have supported and shown concern for the publication and release of the book. I hope this book can play a positive role in spreading some basic knowledge about VFT and promoting the development of the world's power technology.

Despite repeated checks and modifications, it is inevitable that this book still has some inadequacies. We sincerely invite readers to criticize and correct them.
