Preface
After the 20th century, the production of electricity mainly depends on thermal power plants, hydropower stations and nuclear power plants. Tidal, geothermal and wind power are also used to generate electricity where conditions permit. The transmission and distribution of electrical energy is mainly achieved through high and low voltage AC power networks. As the development direction of transmission engineering technology, its emphasis is on researching UHV (over 1 million volts) AC transmission and DC transmission technology to form a larger power network; meanwhile, it is also necessary to study the technical problems of superconductor power transmission. The large-scale power system emerged in the 20th century integrated power generation, transmission, substation, distribution and electricity consumption into an organic whole. It has become a physical engineering system with the widest span of space, strict coordination of time and extremely complicated division of labor.
Since the 1880s, electric power has gradually replaced the steam engine, the technological symbol of the industrial revolution in the 18th century, and become the technological basis of the material and spiritual civilization of modern society. In the past 30 years, HVDC transmission technology has made rapid progress and has been widely used in some transmission fields.
This book is divided into eight chapters to analyze and elaborate the power engineering technology in detail, and the content is comprehensive. We hope this book will be helpful to the related work.
前 言
20世纪以后，电能的生产主要靠火电厂、水电站和核电站。有条件的地方还利用潮汐、地热和风能来发电。电能的输送和分配主要通过高、低压交流电力网络来实现。作为输电工程技术发展的方向，其重点是研究特高压（100万伏以上）交流输电与直流输电技术，形成更大的电力网络；同时还要研究超导体电能输送的技术问题。20世纪出现的大型电力系统将发电、输电、变电、配电、用电诸环节综合为一个有机整体，成为社会物质生产部门中空间跨度最广、时间协调严格、层次分工极复杂的实体工程系统。
从19世纪80年代以来，电力已逐步取代了作为18世纪产业革命技术标志的蒸汽机，成为现代社会人类物质文明与精神文明的技术基础。近30年来，高压直流输电技术进步很快，并在一些输电领域内得到了愈来愈广泛的应用。
本书分八章内容对电力工程技术进行详细的分析与阐述，内容全面，希望能够有助于相关工作的开展与进行。
