摘要
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已独特的优越性。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。
Although directional relay based on positive sequence fault components to other directional relay, they have some problems under particular conditions and circumstances too. This article elucidates a few particular problems based on discussing the principle of directional relay based on positive sequence fault components and proposed some new viewpoints.
