Stability limitations impose constraints on power imports into the Rio Grande Valley, the southern region of Central Power and Light`s (CPL) system. CPL`s parent company, Central and South West Services, sought to identify viable plans for eliminating these constraints to enable power transfers via two 345-kV transmission lines. This project conducted assessment studies of the CPL system, using applications from EPRI`s Power System Analysis Package, and identified two scenarios as the most likely remedial measures required. These consisted of the addition of generating units and the use of series compensation of the two transmission lines, in conjunction with shunt compensation. While Flexible AC Transmission System (FACTS) devices were not indicated in this study phase, the researchers indicated a Thyristor Controlled Series Compensation device could be considered to address a potential subsynchronous resonance issue.
