ABSTRACT
Research of configuration design and setting calculation forsubstation element protection is a very important part of substation relay protection. A reasonable configuration design and setting calculation plays a very important role in a substation and even the whole power system. Element protection involving many device-levelsetting values,which is different from line protection. And the setting values is directly related to the protection principles and technologies. The paper starts configuration design and setting calculation for substation element protection bases on the application requirement of a substation.
At first, the paper begins with a overview and a analysis on the research and present situation and development of the substation element protection, on this basis, the paper start a research on the protection of substation element, including transformer and bus-bar and so on. And then proposed plete configuration design of element bined with the characteristics of the foreign general element protection. And the paper also describes the design principle of the protection scheme and the configuration situation of the protection functions.
Based on the design scheme and basic principle and method of protection setting calculation of the substation element protection, the paper discusses the basic process and the primary results of the setting calculation, and pletes the setting calculation of the foreign substation. Now the settings have been used in the substation and have o
