摘要
为减小过渡电阻对距离保护的影响,提出了一种能在微机保护中实现的新算法。理论分析和仿真试验证明,该算法能消除过渡电阻对距离保护测量阻抗的影响,准确反映故障点到保护安装处的正序电抗。
In order to reduce the impact of transition resistance to distance relay,in this paper,a microprocessorbased protection can be achieved in the new algorithm.Theoretical analysis and simulation experiments shows that the algorithm can eliminate the impact of the transition resistance from the protection,accurately reflects the positive sequence reactance from the point of failure to protection device.
