【摘要】：电力系统已经成为现代社会中重要、必不可缺的系统工程之一。随着电力的产生,人们的生活方式得到了很大的改变,社会、生活已经越来越依赖电力系统。经济社会的发展与建设也愈来愈离不开电力系统的建设。随着电力系统智能性和多样性的发展,智能电网的应用也越来越普及和广泛。目前,很多学者和工作人员对电力系统的运行维护及安全控制问题的研究也越来越关注。变电系统作为电力系统的重要环节,变电站作为电能运行和输送的重要组成部分,其安全运行也至关重要。变电站是对电能的电压和电流进行变换、集中和分配的场所,是联系发电厂与电力用户的中间纽带,其不仅担负着电压变换和电能分配的重要任务,同时也直接关系到电力系统本身的正常安全运行,对社会经济的正常与稳定发展、人民群众的生命财产安全起着至关重要的作用。变电站运行时的安全性和稳定性,直接影响整个电力系统运行的安全与稳定。变电运行维护与安全控制的技术是全国乃至全世界电力工作人员研究的重点,提高变电系统的运行维护与安全控制的技术变得至关重要和迫在眉睫。本文主要阐述了变电站的相关理论知识、变电运行的重要性以及变电运行中常出现的故障问题。介绍了变电系统的组成、分类及工作原理,尤其是对数字化变电站和智能化变电站的技术特点和发展趋势做了详细的介绍。阐述了变电运行的重要性和变电运行维护中容易出现的故障问题,并对产生故障的原因进行详细地分析,同时提出了相应的防范措施。通过对这些故障的分析与整理,指出了变电站的运行维护涉及的不足,并提出了如何保证变电安全运行的防范措施。提高变电运行安全性和可靠性措施方面的研究与分析,对于保证电力系统的稳定与安全具有极为重要的经济意义与现实意义,确保了变电运行安全高效的发展,使变电系统的运行更加安全、稳定、可靠。
[Abstract]:Power system has become one of the important and indispensable systems engineering in modern society. With the generation of electricity, people's way of life has been greatly changed, society, life has become more and more dependent on the power system. The development and construction of economy and society are more and more inseparable from the construction of electric power system. With the development of intelligence and diversity of power system, the application of smart grid is becoming more and more popular and extensive. At present, many scholars and workers pay more and more attention to the operation maintenance and safety control of power system. As an important link of power system, substation is an important part of electric energy operation and transmission, and its safe operation is also very important. Substation is the place where the voltage and current of electric energy are transformed, concentrated and distributed, and it is the middle link between the power plant and the power users. It not only shoulders the important task of voltage conversion and power distribution. At the same time, it is also directly related to the normal and safe operation of the power system itself, and plays a vital role in the normal and stable development of social economy and the safety of the people's life and property. The safety and stability of substation operation directly affect the safety and stability of the whole power system. The technology of substation operation maintenance and safety control is the focus of electric power workers all over the country and even all over the world. It is very important and urgent to improve the operation maintenance and safety control technology of substation system. This paper mainly expounds the relevant theoretical knowledge of substation, the importance of substation operation and the common problems of faults in substation operation. The composition, classification and working principle of substation system are introduced, especially the technical characteristics and development trend of digital substation and intelligent substation are introduced in detail. This paper expounds the importance of substation operation and the trouble problems in the maintenance of substation operation, analyzes in detail the causes of the failures, and puts forward the corresponding preventive measures at the same time. Based on the analysis and arrangement of these faults, the shortcomings of substation operation and maintenance are pointed out, and the preventive measures to ensure the safe operation of substation are put forward. The research and analysis of measures to improve the safety and reliability of substation operation are of great economic and practical significance to ensure the stability and safety of power system, and ensure the safe and efficient development of substation operation. Make the operation of substation system more safe, stable and reliable.
