摘　　要：在一个含分布式电源的微型电网中,数据采集系统的可靠性和数据实时性直接影响到能量管理系统中控制系统作业的正确性和准确性。文章在数据采集系统的设计中,提出利用完成端口与线程池技术相结合的优化通信模型和基于分层管理数据采集对象上下文思想的通信管道维护模型;首先介绍了在数据采集系统中如何建立保证数据实时性以及系统可扩展性的网络硬件平台;其次,从软件的结构模型、数据模型和信息模型3个方面设计软件系统的内部结构,并介绍结构的优化方法;最后,根据上述的硬件和软件系统设计思路在物理平台上予以实现,并通过了专业测试软件的性能测试以及实验室内软件平台各功能模块联调实验。In a micro-grid with distributed power,the reliability and real-time property of data acquisition system（DAS） directly affect the validity and accuracy of control system operation in energy management system.In the process of designing DAS,the optimized communication model by the combination of completion port and the thread pool is proposed,as well as the model of the communication pipeline which is maintained by hierarchical management of contexts of data acquisition objects.Firstly,this paper describes how to create a network hardware platform which ensures the real-time property and scalability of DAS.Secondly,the internal structure of DAS is designed in regard to three aspects of the structure model,data model and information model,and the optimization of the structure is described.Lastly,based on the above software system design ideas,DAS is realized on the physical platform,and validated by the performance test by professional testing software and union-test experiment with each functional module of the platform.
