探析220kV变电站母差保护双重技改的实施

Analysis of the implementation of technology of busbar differential protection in 220kV substation

当220kV变电站母线发生故障时,母差保护能够通过启动保护动作元件来对故障进行及时的切除,从而最大限度地确保电力系统的安全和稳定运行.220kV变电站母差保护双重技改是迫在眉睫的事情,因此本文笔者结合多年工作经验,就220kV变电站母差保护双重技改中遇到的问题和经验体会进行探讨,为今后同类母线保护双重技改提供一些有益的经验.

When 220kV substation busbar failure, bus differential protection can be protected by initiating action components to the removal of the fault in a timely manner, thus ensuring maximum security and stability of power system operation. 220kV substation bus differential protection technical innovation is an urgent matter. Combined years of work experience, I discuss 220kV substation bus differential protection technological problems encountered and offer some useful experience for similar double busbar protection problems in the future.
