采用MMC-RPC治理牵引供电系统负序和谐波的PIR控制策略
PIR Control Strategy on Compensation of Negative Sequence and Harmonic for Railway Power Supply System Using MMC-RPC
摘要
Abstract
In order to govern the problems of negative sequence, reactive power and harmonic in railway traction comprehensively, this paper designs a railway static power conditioner based on modular multilevel converter (MMC-RPC). The frequency adaptive controller of power separation is designed firstly, and then the amount of comprehensive governing to Scott traction transformer power supply system is analyzed from the angle of power. Thereafter, a virtual ac component is constructed and then the mathematical model of single-phase MMC is established. After the analysis of locomotive harmonic current characteristics under the synchronization rotating frame, it is shown that the single phase odd harmonic currents fluctuate by a multiple of 4 in dq frame. The design control strategy is then proposed, which needs less proportional-integral-resonant controllers. Finally, the results of a MMC-RPC simulation model in Matlab have verified the proposed control strategy.关键词
