Photovoltaic power generation and wind power generation are important renewable energy sources in the present power system. However, since these power generations are interconnected to the power system through power converters, the interconnection of large amount of renewable energy sources leads to lower the power system stability due to the lack of the inertial energy of conventional...

In SMES system, the power conditioning system (PCS) interfaces the superconducting magnet and the AC system. At present, PCS generally adopts PWM converter based on the high-frequency switching devices. The converter outputs PWM pulses voltage with steep rising and falling edges. It is transmitted to the superconducting magnet via the cable, which leads to a spike overvoltage at the...

Applying high-temperature superconducting (HTS) tapes to superconducting magnetic energy storage (SMES) is expected to improve small sized high magnetic field coils. In developing high field coils using HTS tapes, however, large electromagnetic forces caused by a large current and high field can degrade the critical current of HTS in the winding. To decrease the electromagnetic forces, the...

SMES coil constructed of YBCO coated conductor has been researched these years for its advantage of stored energy without loss under operated temperature. However, the flexible corc cable which can wind with small radius and can work under high magnetic field may be a promising option for smes coil for higher stored energy and higher current. Therefore, it is necessary to consider the smes...

We have studied magnetic levitation properties for valuable metals by magneto-Archimedes effect under a high magnetic field gradient. In order to enhance the magnetic force factor BdB/dz in vertical direction, a ferromagnetic cylinder and an array of cylinders were set into the room temperature bore of a 10 T superconducting magnet. We optimized the shape and the arrangement of the...

The Einstein Probe Satellite is a mission of the Chinese Academy of Sciences to explore all-sky transient X-ray sources and constantly various X-ray sources, which is planned for launch around end of 2022[1]. It will carry a Wide-field X-ray Telescope (WXT) with a large instantaneous FoV and a Follow-up X-ray Telescope (FXT) with a large effective area and a narrow field-of-view. It is...

Magnets with good field uniformity in a good-field region (GFR) of a certain volume are of interest for various research and calibration applications. Due to their simplicity and relatively low cost, Helmholtz coils have been the preferred magnet system for such projects. With air cooling, the magnetic flux density possible with Helmholtz coils is limited to typically 1 mT or below, and field...

The high temperature superconductor (HTS) direct current (DC) induction heater shows great advantages on high efficiency and heating quality in comparison to traditional AC induction heater. A commercial megawatt (MW) HTS DC induction heater using REBa2Cu3O7-δ (REBCO) conductors has been developed by Shanghai Jiao Tong University and JIANGXI Lianchuang Opto-eletronic Science and Technology...
