摘要

本研究提出了提高风力发电机逆变器的效率，特别是在低风速下，对产生的风能的影响。为了提供详细的分析，在土耳其伊斯坦布尔以一分钟分辨率收集了实际风速数据。风速数据在10米处收集，然后投影到30米处。利用20千瓦风力发电机组系统的技术数据对系统进行建模，并计算风力发电量。数据分析表明，风力发电机组系统大部分时间需要在低风速下运行，因此应设计相应的风力发电电子系统(逆变器)，以最大限度地发挥风力潜力。通过实例研究，评估了逆变电路轻载效率的提高对发电量的影响。

Analyzing the effect of inverter efficiency improvement in wind turbine systems

This study presents the effect of efficiency improvement of wind turbine inverters-especially at low wind velocities-on generated wind energy. In order to present a detailed analysis, actual wind speed data is collected with one minute resolution in Istanbul, Turkey. The wind data is gathered at 10 meters and then projected to 30 meters. Technical data of a 20 kW wind turbine system is used to model the system and to calculate generated wind power. Data analysis shows that the wind turbine system needs to operate at low wind speed most of the time and wind turbine power electronic systems (inverters) should be designed accordingly to maximize wind potential. Case studies are completed to assess the effect of inverter circuit light load efficiency improvement on the energy yield.
