Step-Voltage Regulator Model Test System

open access: green2015 IEEE Power & Energy Society General Meeting, 2015
In this paper, a 4-node test feeder will be proposed as the Step-Voltage Regulator (SVR) model test system. The formulation for modelling a SVR bank consisting on three single phase Type A regulators in raise position will be stated in an extended way. However, the procedure to extend the formulation to any other connection will be also explained, and ...
