摘要

本文研究了同步整流作为提高电池连接的本地制造小型风力发电机(LMSWTs)发电量的解决方案。导出了LMSWT永磁同步发电机(PMSG)同步整流所需电池电压的解析表达式。研究发现，同步整流时的蓄电池电压应比同一发电机的无源整流时的蓄电池电压高2倍。在风力机仿真器上，在稳定风条件下，对LMSWT同步整流、磁场定向控制(FOC)和最优转矩(OT)最大功率点跟踪(MPPT)的性能进行了实验测量。研究发现，无源二极管整流器(DR)配置的年发电量(AEP)估计比同步整流策略低(16-38%)。

Experimental Comparison of Passive and Synchronous Rectification on a Locally Manufactured Small Wind Turbine

In this article, synchronous rectification was studied as a solution to increase the energy yield of battery connected Locally Manufactured Small Wind Turbines (LMSWTs). An analytical expression to determine the necessary battery voltage for synchronous rectification on the LMSWT Permanent Magnets Synchronous Generator (PMSG) was derived. It was found that the battery voltage for synchronous rectification should be two times higher than that of the passive strategy for an identical generator. The performance of the LMSWT under synchronous rectification with Field Oriented Control (FOC) and Optimal Torque (OT) Maximum Power Point Tracking (MPPT) was measured experimentally on a real scale wind turbine emulator under steady wind conditions. It was found that for the passive Diode Rectifier (DR) configuration, the Annual Energy Production (AEP) estimation was (16-38%) lower than for the synchronous rectification strategy.
