Optimization for design and application of data acquisition subsystem in micro-grid energy management system

DING Ming,ZHOU Liang,BI Rui(Research Center for Photovoltaic System Engineering of Ministry of Education,Hefei University of Technology,Hefei 230009,China)  
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.
