Simulation Analysis of Three Software Dielectric Loss Measuring Algorithm

文章介绍了三种绝缘介损监测软件计算方法后,利用MATLAB软件仿真方法,对电容性设备介损监测的谐波分析法、正弦波参数法及相关函数法进行分析比较,得出了在采样精度、采样点数、频率波动、零点漂移、谐波含量变化等影响因素下三种算法的不同结果。对实际绝缘介损在线监测设备的设计提出了有益的建议。

This paper briefly introduces three software dielectric loss measuring methods.i.e.harmonic analysis method, sine wave parameter algorithm and correlation function algorithm,analyzes these three methods under various conditions such as different level of sample accuracy,different number of sample in a single period,fluctuant frequency,zero drifting and disturbance of harmonic content using the simulation approach offered by software MATLAB and presents some instructive suggestions for the algorithm design of dielectric loss measuring equipment.
