对新型正序故障分量方向元件几个特殊问题的探讨

Exploration on Several Special Problems of New Type Directional Element for Positive-sequence Component of Faults

虽然正序故障分量方向元件原理简单，与其它方向元件相比具有自己独特的优越性。但在特殊的条件和环境下，也存在一定的问题。本文在讨论正序故障分量方向元件的原理基础上，针对其存在的几个特殊问题，进行了分析讨论，并提出了新的观点和看法。

Though the principle of directional element for positive-sequence component of faults is simple,and it possesses self-distinctive superiority compared with other directional elements,but it also presents some problems under certain special conditions and envi-ronments.Based upon the discussion on the principle of directional element for positive-sequence component of faults,this paper focusing several special problems about it,carries out the analysis and discussion,and puts forward new idea and views.
