FreeRTOS在微机继电保护实验装置中的应用

The application of FreeRTOS in experimental device for microprocessor-based relay protection

微机继电保护装置在电力系统中的应用越来越广泛。为满足国内高校电力系统继电保护实验教学与生产实际同步的需求,研究了一种基于实时操作系统FreeRTOS的微机继电保护实验装置设计方案。以实时操作系统作为运行环境,使用基于任务的软件设计方法,对实验装置的功能进行了细致的划分,并在此基础上按功能模块化原则制定出各个任务。该继电保护实验装置采用了实时操作系统,软件结构高度模块化,具有简单灵活、操作方便的特点。实际使用表明,此方案能够较好地满足高校实验教学的要求。

microprocessor-based relay protection devices have been widely applied in power system. There are few microprocessorbased relay protection devices for experiments available in domestic colleges. A new experimental device for microprocessor-based relay protection has been designed and developed in order to satisfy the requirements for experimental teaching. This paper brings forward an experimental device based on a free and open source RTOS ： FreeRTOS. The functions of the device are divided into function modules according to the tasks of relay protection experiment. The device applies RTOS as its software runtime platform, which makes the software structure highly modularized, simple and flexible. Also the device is more convenient for operating. The application in colleges proves it efficiency for relay experiment.
