Electrical engineering and its automation technology are the synthesis of the most promising comprehensive discipline and many high and new technologies in the world. Its application range is very wide, which almost permeates all sectors of the national economy. With the development of science and technology in China, the technology of electrical automation is also improved. The era of information and intelligence has come. China is also following the trend of science and technology and the development of the times to move towards the forefront of the times. The development and extension of information technology has promoted the application field and practical scope of electrical engineering automation. This greatly accelerated the development of social industry and science and technology.

This book firstly discusses the position and function of electric power industry in the national economy, as well as the generation, development and innovation of electric power engineering and its automation. Then, the following seven chapters respectively expounds the basic principle of electric circuit, high voltage and insulation technology, electric installation engineering construction motor electrical and electrical new technology such as electrical engineering theory and electrical automation and equipment, electrical automation control, electrical automation scheduling, such as electrical automation technology, in order to provide feasible theory basis for the general electric power workers. This is also the purpose of compiling "Electrical Engineering Automation Technology". As the book contains more content, involves more cumbersome knowledge, and has more compilers, the format, depth and breadth of the contents of each chapter may not be inconsistent; and the fallacies are inevitable. Readers are invited to criticize and correct. Suggestions for improvement will be gratefully received.

With the development of the national economy, China’s transportation industry has entered a new period of development, and the requirements for the quality of engineering construction are also increasing day by day, which means that the standards for railway construction must be improved. In the measurement process of railway engineering, the accuracy of measurement results is directly related to the engineering quality of railway construction and foundation construction stage. The specific performance is as follows: once the construction measurement results are not accurate enough, it will affect the construction progress and adversely affect the overall project quality. Therefore, it must be taken seriously. Before the construction, the original surface of the construction section should be re-tested to make it as close as possible to the construction drawings, so that the construction lofting can be more accurately carried out. When it is found in the measurement process that is inconsistent with the construction drawing requirements, it must be reported for processing at the first time; if the measurement deviation is found in the construction lofting, there will be displacement deviation between the built railway and the designed position. Therefore, in the construction process of railway engineering, it is necessary to attach great importance to the measurement work and fully realize its importance in the whole project.

This book will briefly elaborate on the railway engineering overview, railway subgrade engineering, railway track engineering, railway and bridge engineering, railway and tunnel engineering, surveying, and railway engineering measurement.

随着国民经济的发展，我国的交通运输业步入全新的发展时期，对工程建设质量的要求也在与日俱增，这就意味着铁路工程施工的标准要有所提高。在铁路工程的测量过程中，测量结果的准确性与铁路施工和基础施工阶段的工程质量有直接的联系，具体表现在以下方面：一旦施工测量结果不够精准，会影响施工进度，并给整体工程质量带来不利影响，因此，必须加以重视；施工前应对施工段的原地表进行复测，使其尽量和施工图相符，这样能更准确地进行施工放样；在测量过程中发现与施工图要求不一致的地方时，必须第一时间上报进行处理；如果在施工放样中发现测量偏差，会使建成后的铁路与设计的位置存在位移偏差。因此，在铁路工程的施工过程中，必须对测量工作给予高度的重视，并充分认识到它在整个工程中的重要性。

本书将通过对铁路工程概述、铁路路基工程、铁路轨道工程、铁路桥梁工程、铁路隧道工程、测量学、铁路工程测量等方面进行简要的阐述。
