Relocation of SVC from Shin-Shinano substation to Suruga substation

This paper reports on the successful relocation and reconstruction of an existing static Var compensator (SVC). In 1987, for experimental test purposes, an SVC with a controlled rating of 100 MVAr was installed in the Shin-Shinano 50 Hz-60 Hz frequency converter (FC) substation, on the 50 Hz, 500 kV side, to help control the voltage of the transmission network. Certain components of this test SVC were removed from service and returned to the factory to customize the design to meet the requirements of a new application, and to update and modify the equipment to meet the latest commercial operating requirements. This reconstructed SVC was installed in the Suruga substation, on the 154 kV side. In 2001, the SVC was successfully tested to verify its correct operation and application.
