Application of a dispersed autonomous voltage control system to a real high-voltage distribution network

This paper focuses on the application results of the dispersed autonomous voltage control system, which the authors have proposed, to 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, an SCC is installed together with an SC and/or ShR on the line. Individual SCCs autonomously control the operation of SCs and/or ShRs based on the voltage measured where the SCs and/or ShRs are located on the line. A field test on a real high-voltage distribution network found that the proposed system could sustain a high fault tolerance ability and also be cost-effective in regulating line voltage.
