摘要
提出了以C8051F340增强型单片机为核心的新型低压继电保护装置方案,对低压继电保护设备的原理和需求进行了分析,设计了系统的硬件和软件方案并予以实施和试验。试验结果表明,设备具有结构简单、动作可靠性高、采样精度高、操作方便、接口丰富等特点,能够在复杂的现场完成继电保护的各项功能。
A new design scheme of low-vohage relay protection device based on the enhanced MCU C8051F340 is put for- ward. The principle and requirements of the low-voltage relay protection device is analyzed. The scheme of hardware and soft- ware of the system was designed and implemented. The experiment results of the device shows that the device has many charac- teristics of simple structure, high reliable action, high sampling accuracy, easy operation and abundant interfaces. The device can complete all function of relay protection in the complex situation.
