Entergy Stabilizes Voltage with D-VAR

摘要

Dynamic-VAR solution regulates voltage levels by injecting VARs into the Natchez power grid. LOCATED ON A BLUFF OVERLOOKING ONE OF THE WIDEST BENDS OF THE MISSISSIPPI RIVER. Natchez is one of Mississippi's oldest cities. With its bustling tourism, strong industry and wealth of natural resources, Natchez is a desirable, small city - with a population just under 20,000. The Natchez area is served by five 115-kV transmission lines, the Natchez 75-MW gas-fired steam electric station (SES) and the Murray 20-MW hydro facility. Entergy Mississippi Inc. (Jackson, Mississippi, U.S.) provides electricity service to approximately 427,000 customers in Mississippi across 45 counties, including Adams County in which Natchez is located. In 2005, while studying the possibility of placing the 75-MW fossil unit in reserve, Entergy identified potential dynamic voltage stability issues in the Natchez area.
