In this paper, the motor-generator set was developed to test the various output performance of a 1-kW-class high-temperature superconducting generator (HTSG) which is charged by HTS contactless rotary excitation device (CRED). First of all, the various full components for 1-kW-class HTSG were manufactured and assembled including a salient rotor pole with HTS coils, rotating shafts, torque...
This paper focuses on the design of a Vernier machine with HTS bulks on Flux Modulation Pole(FMP) and HTS field winding. Vernier machine gained importance in recent years for low-speed and large- torque (LSLT) applications, such as wind power generation. Despite the Low-speed high-torque capability, Vernier machine have lower Power factor than the power factor of conventional HTS Field Winding...
China Southern Power Grid, Ltd. has established a project to study the feasibility of installing large-scale HTS dynamic synchronous condensers in Ultra High Voltage Direct Current (UHVDC) transmission grid. To investigate some key technologies, a small–scale one, such as 300-kvar class HTS synchronous condenser prototype is designed. The electromagnetic and structure design of this prototype...
Nowadays, feasibility study of fully turboelectric propulsion systems for electric aircrafts are being conducted. Fully superconducting rotating machine is one of the solutions to realize fully turboelectric propulsion systems with lightweight and high power density. In our previous studies, we reported the high output power density over 20 kW/kg for the 10-MW-class fully superconducting...
This paper presents the results of the electromagnetic design and numerical analysis for a 10-MW-Class second generation high-temperature superconducting generator (2G HTSG). Since the offshore wind power has the technical and economic difficulties in a regular maintenance due to geographical conditions that are difficult to access, the operation reliability of 2G HTS coil for the rotor-field...
