智能变母线差动保护的大差低值和小差高值的调试技巧分析

Analysis on the Debugging Skills of Large Difference Low Value and Small Difference High Value of Busbar Differential Protection of Intelligent Substation

变电二次检修人员在现场对微机母线保护装置进行母线差动比率制动系数校验时,分别校验大差和小差差动比率制动系数的的高值、低值,论文对此展开了论述。

When the substation secondary overhaul personnel check the busbar differential ratio braking coefficient of the microcomputer busbar protection device in the field, they will check the high value and low value of the large difference and differential ratio braking coefficient.To this, the thesis launches the elaboration.
