不同时间级差的两台主变保护动作行为分析

通过电力系统变电站的两台主变压器保护配置中不同时间级差的保护动作行为,在假设条件下,对中、低压侧发生各种短路保护的动作行为进行分析,从而对变压器保护的整定计算提供了分析的依据,提高变电站主变压器的安全稳定运行水平。

Analysis the Different Time Grading's Two Hosts Change the Protection Movement Behavioral

Through in electrical power system transformer substation two main transformer protection disposition different time grading protection movement behavior,under the supposition condition,to,the low pressure side has each kind of short circuit protection movement behavior to carry on the analysis,thus protects to the transformer the installation computation provides the analysis the basis,raises the transformer substation main transformer's security steady operation level.
