摘要: Optimum reactor compensation configurations for implementing single pole reclosing on EHV (extra-high-voltage), double-circuit lines have been previously investigated. However, some applications, optimum schemes may not be practical due to constraints such as physical size, operating and existing equipment. The performance of nonoptimum is considered using an EGAT (Electricity Generating Authority Thailand) 328 km, 500 kV, line example. Several were considered, their was examined with both circuits in service one circuit out maintenance. analysis indicated that values considerably off still provided reasonable performance. >
