基于模块的可编程保护装置软件设计新概念

指出了采用新的软件设计方法设计微机保护装置的必要性和可行性。采用面向对象的设计思想，借鉴可编程控制器的控制方法，提出了基于模块的可编程可配置的保护软件设计方法。这种方法创造性地将保护装置的动作逻辑与程序进行了分离，使得保护具有最大的灵活性。实践证明这种设计方法非常有效地降低了开发工作量和维护工作量。

THE NEW SOFTWARE DESIGN METHOD OF MODULE-BASED PROGRAMMABLE DIGITAL RELAY

This paper points out the necessity and feasibility of a new software design method in developing new digital relays. Under the guidance of the object-oriented idea, this paper presents a new method to develop the programmable digital relays by adopting the programmable and controllable processing technology based on the modules. This method has separated the operation logic of digital relay from the program of digital relay for the first time. It makes the digital relay more flexible. The new method has been put into use and it can effectively reduce the work amount of software development and maintenance.
