深远海风电二极管移相整流送出系统的谐波发射机理及传播特性
Harmonic Emission Mechanism and Propagation Characteristics of Phase-shifted Diode Rectifier-based Deep-sea Wind Power Sending Systems
摘要
Abstract
Phase-shifted diode rectifier(PSDR)can effectively reduce harmonic content in AC systems.It is a solution for achieving low-cost and light-weight design of deep-sea wind power sending systems owing to its significant capability to reduce even eliminate AC filters.This paper investigates the harmonic emission mechanism and propagation characteristics of PSDR-based sending systems.Firstly,physical mechanism of harmonic emission is fully analyzed by the method of positive/negative sequences harmonic phase-shifting,and the factors and laws influencing on the emission characteristics are clarified.Secondly,frequency-domain model of harmonic propagation via offshore AC-grid is established to identify the harmonic distribution pattern between PSDR and wind farm sides.Finally,theoretical findings are validated by simulations and experiments,which demonstrates the effectiveness of low harmonic operation.The study provides valuable reference for PSDR topology design and wind turbine converter optimization.关键词
