center of mass

The FFT (fast fourier transform) algorithm and the mass center notion were used to develop a fast estimation algorithm named the Mass Center Method (MCM).

基于快速傅里叶变换 (FFT)运算和质量中心的概念 ,提出一种快速的高性能估计算法 ,称为质量中心法。

And based on the wide area measurement system,a new system frequency measurement method was proposed,in which the units rotate speed of the system was real-time measured,and then the frequency of system inertia center was calculated out.

分析了传统频率测量方法的局限性,提出以广域测量系统为基础,通过实时测量系统中各机组转速,进而计算出系统惯量中心频率的系统频率测量方法。
