A number of companies in the United Kingdom, the United States, Germany, France, Japan and Russia started SMES R&D work in the early 1970s. Since that time, many SMES projects have been proposed, but only some have been put into practice. The leading roles belong to the United States, Russia and Japan. As reported by the Soviet Academy of Sciences, the first Russian experimental SMES of 104 J energy capacity and with a rated power of 0.3 MW was connected, through a six -pulse thyristor inverter, to the Moscow power system in the 1970s. This experimental SMES was constructed by the High Temperature Institute (IVTAN), which has subsequently been involved in a number of other SMES projects. Since 1989, this work has been done within the framework of the Russian State Scientific 'High Temperature Superconductivity' Programme. IVTAN's latest achievement is a 100 MJ 30 MW SMES installed in the Institute's experimental field, and is connected to the nearby 11/35 kV substation owned by Moscow Power Company. The electrical proximity of the 22 MW and 100 MW synchronous generators, as well as a specially designed load simulator, provides possibilities to conduct full-scale experiments on an SMES's influence on power system behaviour under normal and fault conditions.
