摘要
基于电梯综合治理电压和电流质量问题的需求,提出一种新型的电梯安全卫士(Elevator Safety Guard,EFG)拓扑结构,其由背靠背H桥模块构成。串联单元用于治理电压质量问题;并联单元用于治理电流质量问题,其采用差异化设计,无功电流和谐波电流由不同的模块补偿。串联单元采用解耦控制策略,并联单元采用无差拍控制策略。仿真结果验证了所提拓扑结构和控制策略的正确性。
This paper proposed a novel power conditioner topology as Elevator Safety Guard(ESG)to solve the voltage and current quality problems of the elevator. This topology consists of series converter and parallel converter both based on the back-to-back H-bridge modules. The series converter of the conditioner is used to solve the voltage quality problem while the parallel converter is used to solve current quality problem. Differentiation design is used for the parallel converter. The reactive current and harmonic compensation is executed in different control modules in the parallel converter. The decoupling control is applied in the series converter while the dead-beat control is used in the parallel converter. The effectiveness of the proposed topology and control strategy is validated by simulations.
