摘要

在风电被电网大量吸收、电力系统稳定、负载平衡和频率控制的背景下，风力抽水蓄能系统变得越来越有吸引力。考虑两种不同的拓扑，分别为2L VSC和3L NPC VSC，从2.2 kW到1.85 MW的功率水平，对泵驱动逆变器系统的功率损耗进行了评估。分析基于实际应用，考虑了感应电机的标准低压和中压电源有效值电压以及半导体开关的最新IGBT 3, IGBT 4(沟槽技术)和压包IGBT技术。

Power losses evaluation of two and three-level NPC inverters considering drive applications

Wind pumped storage systems are becoming more and more attractive in the context of higher quantities of wind power to be absorbed by the grid, power system stability, load balancing and frequency control. The power losses of a pump drive inverter system are evaluated considering two different topologies: 2L VSC and respectively 3L NPC VSC starting from 2.2 kW up to 1.85 MW power levels. The analyze is based on practical application considering the standard LV and MV of the induction machine supply RMS voltages and the latest IGBT 3, IGBT 4 (trench technology) and the press-pack IGBT technology for the semiconductor switches.
