摘　　要：论文以典型的电力线路三段式过流保护为主要内容,设计了基于单片机STC89C52三段式过流保护等模拟实验功能;具有体现继电保护不同硬件形态的全面性特点。基于单片机的保护功能除具有三段式保护功能外,还具有零序电流方向保护的实验功能,可用于验证微机式继电保护所具有的可靠性、使用和功能扩展的方便性。Based onthe power line typical three section type overcurrent protection as the main content, design of the MCU STC89C52 three section type over-current protection function is based on simulation experiment;the comprehensive characteristics of different hardware configuration of relay protection. Protection functions based on single chip has three section protection function,but also has the function of zero sequence current protection,and can be used for reliability,convenient use and functional verification of microprocessor relay has extended.
