Abstract: A development frame of hydropower simulation system has been introduced based on model driven architecture，it takes UML as the object-oriented modeling tool ，constructs the system from a higher abstract level，describes and summarizes the function，model structure and level，model transformation and code generation，avoids the flaw of the traditional development，makes system modeling become the core of software development.As a case study，the frame has been tested in Fengman Hydropower Station，Jilin province.The generality，advantage and credibility of the system are validated through this experiment；the new method is suitable to realize the large-scale software development，such as hydropower simulation system.

摘要： 介绍了基于模型驱动架构设计的水电仿真软件开发框架，以UML 作为面向对象建模工具，从更高的抽象层次上构建系统，描述和总结了系统的功能组成、模型结构与层次、模型变换及代码生成，避免传统开发的缺陷，使对系统的建模行为成为软件开发的核心。以吉林丰满水电站为用户案例，对系统进行应用测试，实践验证了该方法的通用性、先进性和可靠性，是一种适合实现水电仿真系统等大规模软件开发的新方法。
