Frequency Response Characteristics of a 100 MJ SMES Coil—Measurements and Model Refinement

Primary frequency control of multi-machine power systems with STATCOM-SMES: A case study

“…1 makes use of a lumped parameters network represented by a 6-segment model comprising self inductances (L i ), mutual couplings between segments (i and j, M ij ), ac loss resistances (R si ), skin effect-related resistances (R pi ), turn-ground (shunt-C Shi ) and turn-turn capacitances (series-C Si ). This model is based on the one previously proposed in [15], and is reasonably accurate for electric system transients studies over a frequency range from dc to several thousand Hertz. Fig.…”

Dynamic Modelling and Control Design of Advanced Energy Storage for Power System Applications

“…The equivalent circuit of the SMES coil makes use of a lumped parameter network implemented by a six-segment model based on Steurer & Hribernik (2005) and Chen et al (2006), as described in Fig. 11.…”

Development of 1 MJ Conduction-Cooled LTS Pulse Coil for UPS-SMES

“…When we designed the test cryostat for the prototype 100 kJ UPS-SMES, the average terminal voltage of the coil was estimated to be around 70 V from the specification of the system. In the test operation, however, the maximum coil terminal voltage became around 300 V because of the insufficient matching of the converter and the coil [5], and it might have exceeded the dielectric voltage of the insulation of the sensor wires Also, some terminals of the wires had been shorted accidentally at the outside of the cryostat.…”
