DEMYSTIFYING IMPEDANCE CALCULATIONS (Lunch & Learn)
This IEEE lunch and learn will cover the basics of performing impedance calculations and converting quantities from the P/Q plane to the R/X plane. The level of difficulty of this material is Intermediate. A background in power system analysis and the per unit system will be beneficial.
This lunch and learn will cover:
Converting quantities from the P/Q plane to the R/X plane
Converting P/Q and R/X quantities from primary to secondary values (as seen from PT and CT)
Converting S and Z from one base to another base.
Plotting generator P/Q diagram in excel format
Plotting generator R/X diagram in excel format
Develop 21 & 40 functions for generator protection
Plotting 21 & 40 settings in excel format
Comparing 21 & 40 settings to generator capability
A PowerPoint and excel file with example calculations will be provided as part of this lunch and learn session.
