摘要

本文介绍了一种针对风力发电机组（WT）转换系统中混合发电机组（HG）的无功功率控制方法。WT通过多端直流（MTDC）电网中的无源整流级连接到中压直流（MVDC）集热器电网。MVDC电网从WTs收集电力并将其发送到海上变电站，在那里DC-DC转换器将电压升压到固定电压的高压DC （HVDC）电网。HG有一个9相定子绕组，包括两个转子，一个永磁（PM）转子和一个绕线场（WF）转子。两个转子安装在同一轴上，以相同的速度旋转。在每个转速下，永磁转子感应到一个固定的定子电压，而感应电压是由WF转子通过控制直流电流进入WF绕组可调。本文介绍了一种通过双环WF转子控制实现的无功功率控制，可以有效地管理HG和WT无功功率。所提出的控制系统是针对MTDC电网中的单个wt和并联wt开发的。仿真结果验证了分析模型，而来自按比例缩小的实验室原型HG的测试结果验证了模拟。

Wind Turbine Reactive Power Control in a Multiterminal DC (MTDC) Wind Generation System

This article introduces a reactive power control tailored for a hybrid generator (HG) in a wind turbine (WT) conversion system. The WT is interfaced to a medium-voltage DC (MVDC) collector grid via a passive rectification stage in a multiterminal DC (MTDC) grid. The MVDC grid collects the power from WTs and sends it to an offshore substation, where DC-DC converters step-up the voltage for transmission to a fixed-voltage high-voltage DC (HVDC) grid. The HG has a 9-phase stator winding and comprises of two rotors, a permanent magnet (PM) rotor, and a wound field (WF) rotor. Both rotors are mounted on the same shaft and rotate at the same speed. At each speed the PM rotor induces a fixed stator voltage, while the induced voltage due to WF rotor is adjustable by controlling a DC current into the WF winding. The paper introduces a reactive power control that is implemented through a dual-loop WF rotor control enabling an effective management of the HG and WT reactive power. The proposed control system is developed for individual WTs and for parallel WTs in a MTDC grid. Analytical modelling are verified by simulation results, while test results from a scale-down laboratory prototype HG validate the simulations.
