摘要/Abstract

摘要：频率测量在自动准同期装置的设计中十分重要，它直接影响到压差、角差计算的准确度和并网的质量.笔者以ATMEGA128单片机为例,结合工程经验,探讨了2种不同的测量办法,对工程应用有一定的借鉴意义.

关键词： 输入捕获, 溢出, 中断

Abstract: Frequency measure is very important in the design of automatic synchronism equipment.The reason lies in the fact that it exerts a direct influence on the acccuracy of the voltage difference ,phase difference and the quality of cutting-in operations.Taking the ATMEGA128 single-chip processor for example,accroding to author’s experience,two methods of measure are proposed in this article,which would be significant for engineering applications.

Key words: input capture, overflow, interrupt
