SCR759 acLineSegment Name Length Increase in Information Model Manager
ReasonMulti-section line models have been used by transmission planners in Siemens Power System Simulator for Engineering (PSSE) power flow software for over 20 years as a tool for correctly simulating contingencies on the ERCOT System for planning studies. The Topology Processor enhancement approved by ERCOT in April 2010 to add multi-section line definitions to the raw file output requires all line segments of the multi-section line to be modeled under the same Line Equipment Container in the Network Operations Model. The reason that some Transmission Service Providers (TSPs) are not modeling line segments in this manner in the Information Model Manager is that the acLineSegment name is currently limited to two characters, which is too limiting for many TSPs line segment IDs. To be able to make this change to the Network Operations Model, the acLineSegment name must be increased. If this increased name size is not changed, the multi-section line functionality of the Topology Processor cannot be utilized.
