传感器安装偏差对功率流测试误差的影响分析
The Effect of Mounting Deviation on Measuring Error of Power Flow
摘要
Abstract
In order to analyze the influence of mounting deviation on measuring accuracy of power flow, the effect of mounting deviation on error of power flow based both on cross spectral density method and wave decomposition method were developed respectively. The mounting deviation was divided into position deviation and angle deviation. It is shown that the two models are identical. The error caused by position deviation is decided by the difference of position deviation between two transducers,the error caused by the angle deviation does not vary with frequency and always make the power flow smaller than normal, and the total error is the product of the both.关键词
