DC transmission Line error "Error in INVCJD. Singularity occurs"
It is being observed that if DC correction is enabled for Overhead transmission ULM. PSCAD gives the error "Error in INVCJD. Singularity occurs" in the case where the ground wire is not eliminated. However, when the ground wire is eliminated the log file is generated correctly. Can someone explain the cause of the error and remedy? The image of both cases has been added here
