Abstract: Aiming at the power conditioning system (PCS) in the superconducting magnetic energy system (SMES) based on voltage source converter (VSC), this paper gave the main circuit structure of PCS in the SMES based on the VSC and Chopper, as well as the low-frequency mathematical model of PCS which is expressed in the functions of duty ratio. The non-linear transformation was
used to linearize state equations to realize the decoupled control between active power, reactive power and DC voltage. The simulated results in Simulink of Matlab showed that the designed PCS has perfect performance in tracing power orders in the form of step and sine waves with strong anti-jamming ability for voltage at DC side.
Key words: power conditioning system; voltage source converter; non-linear transformation; linearization; decoupled control
