秦二厂汽轮机监视与保护

Monitoring and Protection of Steam Turbine in Qinshan Phase Ⅱ

随着汽轮发电机组向大容量、高参数发展,机组的自动化程度也随之不断提高,各类自动化方面的新技术、新系统也在实际电力生产中得到了成功应用。以秦二厂一、二号汽轮机组现实情况为参考基础,重点介绍了汽轮机重要监视仪表概况、基本测量原理、汽轮机保护应用和保护系统的工作原理;并结合工作实践过程中的应用体会和国际国内的实际情况,对汽轮机监视保护仪表的发展、应用予以展望。

With the development of turbogenerator units toward large capacity and high parameters,the degree of automation of turbogenerator units has been continuously improved,and new technologies and systems of various automation aspects have also been successfully applied in actual power production. Based on the actual situation of unit1 and unit2 steam turbines in Qinshan Phase Ⅱ,this paper mainly introduces the general situation of important monitoring instruments,the basic measuring principle,the working principle of protection application and protection system of steam turbines,and prospects the development and application of monitoring and protection instruments of steam turbines combined with the application experience in the process of working practice and the actual situation at home and abroad.
