Analysis and Suppression of Circulating Current for Modular RPC Parallel System
摘要
Abstract
ABSTRACT:This paper presents an equivalent model and circulating current control strategy, suitable for modular RPC (railway static power conditioner)parallel system. Firstly, a topology of parallel RPC system is proposed. This topology is convenient for modular extension and can remain working when failure happens on one sub-module. Generation and damage of circulating current in multi-parallel systemare analyzed based on the topology. A distributed control scheme is put forward and a novel simplified PWM (pulse width modulation) strategy is introduced for circulating current restraining. System simulation is performed based on four-parallel-RPC system to verify feasibility of the control scheme.关键词
