基于模型驱动架构的电力信息系统快速开发方法

针对电力行业信息系统建设和整合集成中存在的功能模块重复开发、系统维护代价较高的现状，文章提出一种基于模型驱动架构的电力信息系统快速开发方法，首先通过分析典型电力信息系统的共性功能抽象出电力信息系统元模型，然后以UML活动图的形式搭建系统业务流程，并通过模型一代码转换引擎将业务流程图实例化为特定平台上的业务代码，最后在电力信息系统综合业务平台中即可动态加载并运行该业务。建模实例表明，文章方法在减少重复开发工作量、降低系统维护成本方面有较好的适用性。

A Rapid Development Approach for Electric Power Information Systems Based on Model Driven Architecture

During the construction and integration of electric power information systems, there commonly exists the duplicated developed functional modules and high cost system maintenance. This paper presents a model- driven architecture based on a rapid development method for the electric power information system. First, meta- models of electric power information system are abstracted by analyzing typical common power information system features. Second, we generate the business processes by the UML activity diagram, and through the model-to-code transformer, the business flowchart is instantiated into a platform specific business source code. Finally, the business source code can be dynamically loaded and run on the integrated services platform （ISP）. Experimental results of several modeling scenarios show that our method is applicable for reducing duplication development and lowering the system maintenance costs.
