Superconducting magnetic energy storage (SMES) system is getting increasing acceptance in variation applications of power system because of its higher efficiency and faster response. This paper proposes a high quality power conditioner system for the SMES system operation. The power conditioner consists of a voltage source converter using IGBT (Insulated Gate Bipolar Transistor). In order to compensate...
Recently, utility network is becoming more and more complicated and huge due to IT and OA devices. In addition to, demands of power conversion devices which have non-linear switching devices are getting more increased. Consequently, because of the non-linear power semiconductor devices, harmonics current is unavoidable. Sometimes those harmonics current flows back to utility network and become one...
