摘要
针对液压型风力发电机组低电压穿越过程存在的问题,对该过程机组主传动系统瞬态特性展开了研究。建立了液压主传动系统瞬态模型,并通过AMESim与Matlab/Simulink仿真技术搭建了联合仿真平台。仿真分析了不同工况和管道长度对主传动系统瞬态特性的影响规律。研究结果表明,提升泵转速有利于系统快速响应,缩短管道长度有利于发电功率快速调整。研究工作为开展低电压穿越控制、主传动系统液压管路优化等提供理论依据和先进的技术手段。
In order to solve the problems of hydraulic wind turbine at low voltage ride through（LVRT）,the research on transient characteristics in the main transmission during LVRT was launched.Transient model of the hydraulic main transmission was established,and co-simulation platform was built based on AMESim and Matlab/Simulink simulation technology.Effects of different conditions and pipehne length on the laws of the transient characteristics in the main transmission were analysied in a simulation study.Simulation results show that enhancing the pump speed is conducive to rapid response of the system,and shortening the length of the pipeline is conducive to rapid adjustment of the power generation.Research work provides a theoretical basis and advanced technology for the control of LVRT and optimizing hydraulic lines in the main transmission system.
