Application of Reusable Pattern in IEC 61850 Unified Modeling
Xiang Nan · Hydropower Automation and Dam Monitoring · 2012
Aim at requirements of expandability and reusability of implementing unified modeling in IEC 61850 standards for hydropower plants,several reusable design patterns used to construct the software framework are proposed.During modeling for hydropower plants,MVC pattern is adopted for integral architecture of the software.Implementation of the software is divided into show,business logic and enduring layer,which in logic separates modular of user interface,modular of data processing and modular of accessing to database.Composite pattern description is utilized for device logical nodes and data nodes in order to satisfy the requirement of hierarchical structure of IEC 61850.The application of these reusable patterns constructs a loose-coupled software system.This makes the software more expandable and more reusable,and finally reduces difficulty and cost of maintenance.
