摘要
风力发电机组运行是在特定环境之下进行的,基于特殊环境,双馈风力发电机组与电网连接过程中可能出现稳定性不佳、故障频发的现象,影响了系统的正常运行。本文结合不平衡电压针对双馈风力发电机组的影响,针对1.5MW双馈风力发电机组开展仿真分析,综合各项数据研究分析不平衡电压对变频器交、直流侧产生的影响,提出采取相应的控制策略,促进风力机组的顺利运行。
Abstract
The operation of wind turbines is carried out in a specific environment. Based on the special environment, unstable stability and frequent failures may occur in the process of connecting doubly-fed wind turbines with the power grid, which affects the normal operation of the system. In this paper, combined with the influence of unbalanced voltage on doubly-fed wind turbines, a simulation analysis is carried out for 1.5MW doubly-fed wind turbines, and the influence of unbalanced voltage on AC and DC sides of frequency converters is studied and analyzed by synthesizing various data, and corresponding control strategies are put forward to promote the smooth operation of wind turbines.
