This is a distance relay protection scheme in PSCAD. Four transmission line PSCAD functions are used to model two 100km transmission lines and simulate faults along the lines. Tline1+Tline2=100km and ...

Abstract: Based on PSCAD/EMTDC, the modeling and simulation of an actual protective relay has been studied and developed. To simulate an actual SEL321 relay, the function elements of SEL321 relay have ...

ABSTRACT: The fault recovery of VSC-HVDC transmission system is often influenced by many factors, such as the reactive power compensation characteristics of the inverter and the dynamic performance of ...

Abstract: The challenges of integrating inverter-based resources (IBRs), especially low-frequency instability, are globally concerning. While current responses mainly rely on time-domain simulation to ...
