secondary system error
解釋
次系統誤差-
The presented dissertation mainly discusses the non - linearity existing in monostation and multistation radar measurement. the first part of this dissertation integrated the non - linearity with the uncertainty of measurement system, and presents a secondary order filter for correcting measuring variance while the measurement equation is non - linear. by comparing the filter error of extended kalman filter with that of secondary order filter, we find the filter performance of these two filters are almost same
本文主要討論單站與多站雷達中的非線性測量問題,在1中,我們把測量系統的非線性與測量系統的不確定性聯系起來,針對只有測量方程是非線性的情況,給出了一種修正測量方差二階濾波器,並用這種二階濾波器分析了推廣kalman濾波器的濾波誤差,指出推廣kalman濾波器與二階濾波器相比,濾波性能幾乎相同。 -
With the increase of the electric power system capacity as well as the short lines, high currents will possibly occur in the transmission line when a fault happens at the end of the line. the iron core of the current transformer ( ct ) will become saturated easily because of the large current, or when the secondary load of the ct does n ' t match the 10 % error curve
隨著電力系統容量增大以及短線的增加,在電力系統線路末端發生短路時,有可能出現很大的短路電流;在很大短路電流的作用下,或由於電流互感器二次側負載與10誤差曲線不匹配等原因,電流互感器鐵芯很容易飽和。
