基于数据流的风力发电变流系统控制软件设计

Design of Control Software for Wind Power Generation Converter System Based on Data Flow

风能作为可再生能源的重要组成部分,近年来倍受关注.对于风力发电机组,并网变流系统是决定其输出电能质量的关键环节.采用PEBB电力电子集成模块化设计方法,设计了变流系统的硬件结构,然后应用数据流体系设计其控制软件.通过搭建的直驱风力发电变流系统实验平台,观察了有功调节、无功调节以及在外界扰动下系统的抗干扰性能实验结果波形.实验结果表明设计的风力发电变流系统控制策略及软件符合技术指标要求,提高了风电变流系统的工作效率及其经济效益.

As an important part of renewable energy, wind energy has attracted more and more attention in recent years. The grid con-nected converter system is the key link for the output power quality of wind turbine. In this paper, the hardware structure of the con-verter system is designed based on the PEBB power electronics integrated modular design method, then the data flow system is used to design the control software. Through the experimental platform of direct wind power - drive converter system, the waveforms of the anti -jamming performance experiment were observed in cases of active power regulation, reactive power regulation and subjected to exter-nal disturbance. The experimental result shows that the design of wind power converter system control strategy and software accords with the technical requirements, and can improve the work efficiency and economic benefits of wind power converter system.
