摘　　要：当前国内变电站均已实现微机保护,微机保护是通过对高压电网的电流、电压等电气量进行采样,由程序对采集到的数据进行处理、运算、分析及判断,实现对电力系统故障的识别与诊断。要保证保护装置准确性,除了硬件满足要求外,对软件也有极高的要求,好的保护算法极其重要。单个微机保护的核心是快速性与准确性,而在现有的硬件技术条件下,要满足保护的性能要求,一个重要的突破口就是对软件算法进行优化改进。At present,all domestic substations have realized microcomputer protection.Microcomputer protection is to realize the identification and diagnosis of power system faults by sampling the electrical quantities such as current and voltage of the high-voltage power grid,and processing,calculating,analyzing and judging the collected data by the program.To ensure the accuracy of the protection device,in addition to meeting the requirements of the hardware,there are also extremely high requirements for the software.A good protection algorithm is extremely important.The core of a single microcomputer protection is speed and accuracy.Under the existing hardware technical conditions,to meet the performance requirements of protection,an important breakthrough is to optimize and improve the software algorithm.
