This contract concerns the development, design, manufacture, installation, and field test of a static VAR generator (SVG) at the Minnesota Power and Light Shannon Substation. Broadly, the objectives of the project demonstrate the design methodology, the practicality, and the efficiency of static VAR control for power transmission systems. The program covers development, design, and installation of a 40-MVAR thyristor-controlled, inductive reactor in parallel with two 35-MVAR, shunt-capacitor banks to control a 230-kV transmission voltage. This research evaluates the SVG performance over a wide range of conditions. Within the scope of the project are the SVG switches and their controls configured to provide continuous control over the net reactance applied from 70 MVA capacitive to 40 MVA inductive; the filtering necessary to prevent injection of harmonic disturbances into the transmission line; the protection equipment required; the switch cooling apparatus; and the monitoring and display facilities needed to operate the system. This final report draws together in a single document all of the analytical and design description background material which has been developed during the project execution, and presents the empirical data generated during the twelve month field tests.
