西门子保护与其他国产微机保护的几点区别

西门子微机保护以硬件质量好,可靠性高在重庆地区逐步得到应用。但是国内外微机保护设计和使用习惯的不同使得该保护在电力系统应用时会遇到某些共同性的问题。通过实例介绍了西门子保护在应用于电力系统变电站时,在继电保护、自动装置以及监控等二次设计方面与使用常规国产设备的变电站的某些不同之处,为更好地掌握西门子保护的特性,以便更好地将其应用于今后变电站的设计而进行了探讨。

Differences between Siemens protection and the other relay protections homemade

Siemens protection is gradually applied in Chongqing because of its good hardware quality and high reliability. But some common problems appear since it has been adopted in electric power system. It is because of the differences of the design and manage routines between the overseas relay protections and the homemade relay protections. The paper introduces some differences on relay protection, automechanism, monitoring and control when Siemens protection is applied in electric power system substations from the general power system substations which have the regular homemade equipment. The conclusion in this study are drawn for mastering the characteristics of Siemens protection better in order to its good application on future substation design.
