摘要
静止功率调节器是一种有效的电能质量综合补偿装置,针对电力牵引系统电能质量综合补偿的需求和功率调节器经典滞环控制技术存在稳态误差大的不足,论文深入研究一种基于准比例谐振控制的改进滞环控制策略,通过运用准比例谐振控制来合理设置滞环控制的环宽值,可以充分利用滞环控制响应速度快的优势和准比例谐振控制跟踪性能好的优势,可以最大限度抑制滞环控制稳态误差大的不足和准比例谐振控制响应速度慢的不足。最后通过实验样机验证论文所提方法的可行性和有效性。
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.
