PQSpotlight STATCOM Postpones the Need for 161-Kv Line - Load growth and known voltage problems prompt TVA to install reactive compensation to defer a new 50-mile transmission line

摘要

Leake is a 161/46/13.2-kV substation located close to the southern border of the Tennessee Valley Authority (TVA; Knoxville, Tennessee, U.S.) supply area in Mississippi (U.S.), serving the Central EPA distribution company at 46 kV and 13.2 kV. In 2001, the area peak load of 130 MW had load growth estimated at 4.1% per year. Studies by TVA's bulk transmission planning group indicated the Leake area was susceptible to voltage problems. Possible remedial measures included a near-term plan to rebuild and convert the Leake-Sebastopol-Lake 46-kV line to 161 kV, and a long-term plan for a new 50- to 60-mile (80- to 97-km) 161-kV line from the Red Hills Generating Station to Leake Substation.
