切换开关关断故障特征的快速数值计算方法
Fast Numerical Method for Block Switch Turn-Off Fault Characters
摘要
Abstract
In the fault diagnosis of sectional power supply system,focus on the switch fault calculation time overhead prob?lem,this paper proposes a method of fast numerical calculation. The recursive formulas are designed for duty ratio of current zero crossing signal and current local numerical integral value. Comparing with the conventional numerical method,the computation time can be significantly reduced without reducing the accuracy of the calculation. Finally,the experimental results show that the pro?posed method can effectively improve the efficiency of the fault diagnosis.关键词
