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

In a Micro-grid research platform by studying distributed generation with distributed power, the reliability and data real-time of Data Acquisition System, directly affect the validity and accuracy of Control System Operation. In the process of design Data acquisition system, we put forward the optimization communication model by the combination between completion port and the thread pool, the model of the communication pipeline maintenance with the hierarchical management of data collection objects´ contexts. Firstly, Data Acquisition System established the network hardware platform which ensures real-time data and scalability system. Secondly, the internal structure of DAS is designed by three aspects of the structure model, data model and information model, describing the optimization structure. Lastly, based on the above software system design ideas, DAS was realized in the physical platform, reached the performance testing by professional testing software and union-test experiment with each functional module of platform.
