【摘要】 由对称分量导出了只有两相装设电流互感器的正、负序滤过器表达式,分析了正、负序分量滤过器基本原理,得出中性点不接地系统获取序分量的方法。分析了直接移相序分量滤过器算法,提出了其一般表达式,可根据工程实际选择应用。更多还原

【Abstract】 Expressions of positive and negative sequence filters installed current transformers only on two phrases are derived from symmetrical component.The paper analyzes the basic principles of positive and negative sequence component filters,and obtains the method of achieving sequence component in neutral non-grounding system.Algorithm of direct phrase-shift sequence component filter is also analyzed and its general expression is presented,which can be used selectively in projects.更多还原
