Compensator for variation in distribution line voltage

摘要: PROBLEM TO BE SOLVED: To provide a distribution line voltage variation compensator which reduces the size of static var compensator, and facilitates its assembling. SOLUTION: A step regulator (SVR) 3 for (SVC) 4 are connected to 2. The SVR is caused perform adjustment operation, so as make within dead zone. upper limit value control target larger than zone SVR, lower smaller set SVC. When installation point SVC increased decreased, operation performed, returns instantaneously, by injecting reactive current from line, respectively. With progress quantity compensation transferred output made zero, before completed. COPYRIGHT: (C)2002,JPO
