| 摘 要： | 目前,电流互感器在应用上最大的问题是电流互感器饱和后其二次侧电流波形的失真,使流入继电保护装置中的电流不能真实反映一次系统的电流实际值,从而造成保护拒动或误动情况的发生.在分析不同因素引起的电流互感器饱和波形特征的基础上提出了电流互感器饱和检测的新思路. |
| 关 键 词： | 电流互感器饱和 饱和类型 饱和检测算法 |

| Abstract: | At present,the most serious problem in the application of Current Transformer is the phenomenon of its core's saturation.A Current Transformer cannot transfer the waveform of its primary system correctly during its saturation.As a result,it will influence the reliability of system's protective relaying.Based on the phenomenon of Current Transformer saturation and its great influence on protective relaying,this paper describes the different types of Current Transformers saturation and the characteristics of the wave form supplied by the saturated Current Transformer.The paper introduces a new method of Current Transformer saturation detection algorithm. |
| Keywords: | current transformer saturation saturation type saturation detection algorithm |
