The static power conditioner(SPC)is an effective power quality comprehensive compensation device. In view of the demand for comprehensive compensation of power quality in electric traction systems and the shortcoming of large steady-state errors of classic hysteresis control technology of the static power conditioner
in this paper
a kind of improved hysteresis control strategy based on quasi-proportional resonance control is studied deeply. The ring width of hysteresis control is set reasonably by the use of quasi-proportional resonance control. The advantages of fast response speed of hysteresis control and of good tracking performance of the quasi-proportional resonance control can be used fully can suppress as much as possible the shortcoming of large steady error of hysteresis control and the slow response speed of quasi-proportional resonance control. Finally
the feasibility and validity of the method proposed in the paper are verified by experimental prototypes.
