Description
It is urgent to address the problems of reactive power imbalance in the power grid with a high proportion of renewable energy. Compared to traditional reactive power regulation devices, a superconducting synchronous condenser is an appreciate choice due to its higher power density, faster response time for reactive power regulation, and higher operational efficiency. To minimize the mass and volume of the 50 Mvar superconducting synchronous condenser simultaneously, a multi-objective optimization approach combining Taguchi and finite element method (FEM) is proposed. After optimization, the mass is 20.232 tons and volume is 3.523 m³. An experimental platform is built for testing current carrying performance of the racetrack coil that is wound by REBCO superconducting tapes and cooled by liquid nitrogen. According to the results, critical current of the racetrack coil is about 1.3 times the maximum operational current. It shows the racetrack coil has the excellent stability margin.
