At present, China’s power consumption has been in the forefront of the world, and electrical safety has become a key factor in China’s electrical development. The requirements for electrical safety engineering technology are also increased, and the standards for electrical safety are gradually improved. In order to ensure the electrical demand of our people, it is necessary to conduct a comprehensive analysis and research on the electrical safety engineering technology, constantly update and develop it, build a perfect electrical safety engineering technology system, and apply its implementation to the electrical safety engineering of our country.
The task of electrical safety in engineering technology is to perfect and develop electrical safety technology methods, in order to establish a complete electrical safety system, and pay attention to the development of advanced automation technology and electrical detection and monitoring technology in the field of safety. The task of management science is to gradually improve the electrical safety level of relevant personnel, gradually realize the standardization of electrical safety, introduce the method of system engineering, and improve the scientificity of electrical safety management. This book focuses on electrical technology, with electrical safety methods and electrical risk factors as the main line, introduces various theories and engineering methods for preventing electrical accidents.
In the mid-1990s, China began to carry out the pilot application of microprocessor-based substation protection and control. At present, the intelligent relay protection and monitoring system has been fully realized. Since 2005, with the application and promotion of IEC 61850 standard, a wide range of digital substation pilot projects have been started in China. The pilot projects have made a lot of innovative achievements in electronic transformer, process layer data transmission, IEC 61850 implementation specifications, and digital substation engineering implementation.
In the intelligent substation, the combination between primary equipment and secondary equipment should be closer, both in the space distance and in the function coordination. Through full understanding of each other, the substation can be simpler, more reliable and easier to maintain: in the intelligent substation, the secondary specialty should also be fully integrated. The secondary equipment should be designed from the perspective of reliability, operation and maintenance convenience, and the overall planning should be integrated into an organic whole; intelligent substation serves for more intelligent power grid operation control system. Providing real-time accurate and reliable data should be an important goal of intelligent substation. The design of advanced application should consider more the combination with remote control than only local application.
In addition, intelligent auxiliary integrated monitoring system is a new field in power grid engineering, involving computer software and hardware, communication, power grid automation, security, fire protection, intelligent video, artificial intelligence, power environment monitoring and many other professional fields, which requires high technical reserve for users. At present, most of the power grid operation and maintenance managers are still unfamiliar with this system, and lack of targeted books on the market. Therefore, we have compiled this book to serve the effective application of this system, and then serve the power production and operation.
20 世纪 90 年代中期我国开始进行变电站保护和控制微机化应用的试点，目前已经较为全面地实现了智能化继电保护和监控系统。 2005 年以来，随着 IEC 61850标准的应用推广，国内开始了广泛的数字化变电站试点，试点在电子式互感器、过程层数据传输、 IEC 61850 实施规范、数字化变电站工程化实施方面取得了大量的创新成果。
智能化变电站中一次设备与二次设备之间的结合要更为紧密，既体现在空间距离上也体现在功能配合上， 通过相互充分的了解， 让变电站更简单更可靠更易维护：智能化变电站中二次专业内部也应充分融合，二次设备应从可靠性、运行维护方便性角度，整体规划一体化设计，成为一个有机的整体；智能化变电站为更智能的电网运行控制系统服务，提供实时准确可靠的数据应成为智能化变电站的重要目标，高级应用的设计应更多地考虑与远程控制的结合而非仅本地应用。

As a position to cultivate high-level talents with new knowledge, new ideas and new technologies, culture is the main position for colleges and universities to lead ideological and political education with the socialist core value system. It is an important task for colleges and universities to strengthen ideological and ideological construction, improve their ability to solve practical problems, and deepen ideological and political education, create good psychological conditions for the educated to accept ideological and political education. The deep integration of college students’ mental health and ideological and political education is conducive to providing guidance for the development of students’mental health.
Mental health is mainly to improve mental quality, and the main solution of ideological education is the ideological field. If the mental health of college students and ideological and political education in colleges and universities are organically combined, complemented, promoted and improved each other, so that the mental health education and ideological and political education can achieve twice the result with half the effort.
Landscape engineering is to beautify the environment, which is scientific and regular in a certain range. The value of art appreciation should be reasonably built in the local green space or landscape architecture. The development of landscape engineering is related to the development of regional economy, environment and culture. Since the Reform and Opening up, with the rapid development of social economy and the acceleration of urbanization, various environmental problems have gradually emerged; however, the improvement of people’s material and cultural living standards also puts forward higher requirements for spiritual needs. People’s desire for nature and the pursuit of beauty give birth to the further development of garden industry. Landscape architecture is a subject, a career and an art. Landscape can be divided into two categories: natural landscape and human landscape. Natural landscape came into being before human beings, such as land, rivers and oceans; the human landscape is produced after human civilization. It is a kind of landscape which has been injected into human’s ideas and activities after the transformation of nature. From the perspective of aesthetics, landscape art comes from nature and life. In people’s life, the pursuit of beauty has never been interrupted, nor has art creation been interrupted to achieve this goal. In general, people pay more attention to the formal aesthetic feeling of landscape. The beauty of landscape comes from its artistic creation. Therefore, when people appreciate and evaluate the beauty of landscape, they focus on its artistry. At the present stage of landscape development, because the construction and design are in a stage of continuous improvement, the two important parts of landscape should be explored and studied, so that the landscape engineering becomes more systematic and scientific.
This paper starts with the basic concepts of landscape and landscape design, and introduces in detail the preliminary preparation, construction technology, construction management, concept and application of landscape technology, and safety management of landscape.
