Experimental studies flexible alternating current transmission systems on the phase inverter transformer basis

One of the ways of existed system interconnections usage effectiveness increasing and their static and dynamic stability providing is flexible system interconnections (FSI) usage. The flexible system interconnections alternative variants on phase inverter transformer (PhlT-TS) basis research is the matter of current. In this report one can find the results of PhlT-TS experimental sample studies in different frequency operating conditions of hydroelectric power station (HPS) main generator connection with the energy system. The calculated and experimental results comparison proved the adequacy of PhlT-TS mathematical models developed before. Technical and economic indices and perspectives of PhlT-TS use are also estimated here.
