适用于交直流互联电网的动态等值软件设计

A Software Design of Dynamic Equivalent for AC/DC Interconnected Power Grid

提出了一种适用于交直流互联电网的动态等值软件设计方法。首先,深入研究了交直流互联电网动态等值中的关键问题;然后按照功能需求,以模块独立、数据交换分离、灵活扩层的设计思路搭建了软件框架;最后采用面向对象的元件统一建模技术开发出了可与多种电力系统分析软件交互的、易于扩展的新型动态等值软件,并通过实际运行数据检验了所开发软件的有效性。

This paper proposes a new software design method of dynamic equivalents for AC/DC interconnected power grid. First, some critical issues of dynamic equivalents for AC/DC interconnected power grid have been intensively investigated. Then, considered the function requirements, it builds a general framework for the dynamic equivalents software, which follows the design routine of separateness of modules and data switching and flexible extensibility. Finally a new software tool for dynamic equivalents is developed with OOP technics and unified modeling and a case has been studied to validate the performance of the newly developed software.
