Abstract

Micro-wind turbines incorporating permanent magnet synchronous generators are among the suitable power sources for telecommunication equipment especially in remote areas. Average-value modeling is indispensable for large- and small-signal analysis of such machine-converter systems. However, analytical derivation of accurate models is challenging particularly at low voltage applications due to the non-ideal characteristics of semiconductor switches (rectifier diodes). This paper presents a numerical average-value model of micro-wind turbine generator system. The model parameters are extracted using detailed simulation which avoids laborious analytical derivations. A detailed model of the system is implemented and validated experimentally. The proposed average-value model is verified against measurement and detailed simulation and is shown to accurately predict the response of the system to changes in the wind speed. An improvement in simulation speed of 1,951 times over the detailed switching model is demonstrated.

用于电信供电的单机微型风力发电系统动态建模

包含永磁同步发电机的微型风力涡轮机是电信设备的合适电源之一，特别是在偏远地区。对于这类机变系统的大信号和小信号分析，平均值建模是必不可少的。然而，由于半导体开关(整流二极管)的非理想特性，精确模型的解析推导具有挑战性，特别是在低压应用中。本文建立了微型风力发电机组系统的数值平均值模型。模型参数的提取采用详细的仿真方法，避免了繁琐的解析推导。建立了系统的详细模型，并进行了实验验证。通过实测和详细的仿真验证了所提出的平均值模型，表明该模型能够准确地预测系统对风速变化的响应。与详细的切换模型相比，仿真速度提高了1951倍。
