摘要(Abstract)：

二极管不控整流单元作为海上风电送出系统的整流侧器件是海上风电领域的技术热点。二极管不控整流一般选择多重化整流电路，以12脉波整流电路居多。通过对多重化整流电路中的12脉波整流电路和24脉波整流电路的串联多重联结和并联多重联结分别进行理论分析，研究其交流侧电流和直流侧电压的谐波特性，得出其谐波次数与谐波幅值的计算方法，求出电流谐波总畸变率和电压纹波因数。对比分析12脉波整流电路和24脉波整流电路的特性，探讨将24脉波整流电路应用于二极管不控整流单元的可行性，并基于PSCAD/EMTDC进行了仿真验证。
As the rectification-side devices of the offshore wind power transmission systems, the diode uncontrolled rectification units are a technological hotspot in the offshore wind power sector. Multiplex rectifier circuits are usually employed for diode uncontrolled rectification, with a 12-pulse rectifier circuits being the most common. Theoretical analyses of serial and parallel multiplex wiring in the 12-pulse and the 24-pulse rectifier circuits within the multiplex rectifier circuits have been conducted. This entails studying the harmonic characteristics of the alternating current on the AC side and the voltage on the DC side, deriving the calculation methods for the harmonic numbers and the harmonic amplitudes, and determining the total current harmonic distortion rate and the voltage ripple factor. Comparative analyses are made on the characteristics of 12-pulse and 24-pulse rectifier circuits, investigating the feasibility of applying the 24-pulse rectifier circuits in the diode uncontrolled rectification units. Simulations are carried out on the PSCAD/EMTDC platform.
