SIR.BAS is one of many sample PowerScript programs that are included in every OneLiner V14 installation. Users can run this script to to compute source impedance ratio of lines at some selected bus.
It was discovered that the version 1.0 of SIR.BAS script, which was shipped with OneLiner V14.5 and earlier utilized an inferior source impedance calculation method. As the result the source impedance ratio value reported by the script can be off significantly in some OLR networks.
We had enhanced the source impedance calculation in the version 2 of SIR.BAS. This script program version is being shipped with OneLiner V14.6 and later.
You can also download SIR.BAS script version 2 from ASPEN PowerScript exchange on GitHub:
