【摘要】 频率作为反映电能质量的重要参数,它的精确测量是衡量整个电力系统是否健康运行的重要依据,而且是电力系统其他参数数字化测量中首先要解决的问题。本文对几种常用的频率数字化测量方法进行了仿真,并对它们的测量精度,适应范围,优缺点做了比较。更多还原

【Abstract】 Frequency is taken as the important parameter which could reflect the power qualities. The exact measure of frequency is one of the most important evidence which could scale the healthy running of the power system. Furthermore it is the first problem of other power-system parameters that must be resolved. This article bringed forward a few digital measures and gave the emulation. And making the comparison on precision, using areas and merits and shortcomings.更多还原
