Abstract
Currently, the large amount of data collected from grid-connected photovoltaic(PV) is mainly unstructured, the processing, storage, and representation of which are different in various application systems. The characteristics of the data are dispersive and heterogeneous. Serious ‘data island’ problem is caused since the data directly connected to large data centers does not obey unified standard, whose value, therefore, cannot be fully excavated. In the light of the facts above, this paper developed efficient management platform and data interface module software system for PV power station based on B/S architecture of Java 2 Platform Enterprise Edition(J2EE), designed hierarchical architecture of system with the method of component-based service-oriented architecture(SOA), and built components and services through object-oriented approach based on JAVA. Effectiveness of developed software system has been verified in the construction of large data center for clean energy in State Grid Qinghai Electric Power Company. The system has a uniform and concise user interface, offers a strong extensibility, reusability, and performance, which can enhance efficiency of applying and sharing level of data resources.
