Description
Summary:High temperature superconducting (HTS) cable is a new development of applying superconducting technology in power system. AC loss measurement technology is a key factor in designing HTS cable as it decides the stability and operating cost of the cable. In this paper, a novel AC loss measurement technology for HTS cable is proposed based on LabVIEW. A compensation coil with large current carrying capacity and a stepping motor are used to test the variation of AC losses of HTS cable. A closed loop system is developed to obtain AC losses measured using modules of high-precision Data Acquisition (DAQ) and motion controller of National Instruments (NI). Finally, AC losses of a 0.2 m, 110 kV/1.5 kA prototype HTS cable are measured at 49.9 Hz and 60 Hz frequency considering compensation coil and lock-in amplifier. Obtained results show that AC losses linearly increase with the transport current in logarithmic coordinates. The comparison results applying with compensation coil and lock-in amplifier prove that the proposed measurement system is effective in measuring AC loss of HTS cable with large current capacity in different frequency.
