Abstract
This paper describes the application results of the dispersed autonomous voltage control system, which the authors have proposed, on a real distribution network. This system is effective for regulating the supply voltage of an entire HV line within an optimum range. In the system configuration, a self-control voltage compensator (SCC) is installed together with a static capacitor (SC) or shunt reactor (ShR) on the line. Individual SCCs autonomously control the operation of SCs and ShRs, based on the voltage measured where the SCs or ShRs are located on the line. A field test on a real network proved that the proposed system can sustain a high fault tolerance ability and high cost performance.
