Based on flux linkage locus and PWM driven signal at zero crossing of motor phase current, the reason of such distortion is analyzed, and a current compensation method was brought forward, namely, the PWM pulse width in a carrier period should be adjusted immediately after one p.

Research on measurement of resistive current in XLPE cable using capacitive current compensation method;

The improved capacitive current compensation method considers and compensates capacitive harmonics current generated by voltage harmonics,so it has high accuracy in integer period sampling.

The error,caused by power system harmonics,in measuring resistive current of metal oxide surge arrester can be lessened by improved capacitive current compensation method.

The natural compensating method (the new compensating method)which,by adopting overlong pipe in longitudinal piping section,uses t.

Puts forward the significance of electric grid make reactive compensation,concretely illustrates the principles of reactive compensation,stressfully describes the merits and weak points of several kinds of reactive compensation methods,and suitable condition,offers individual opinion on the development of reactive compensation technology.

This paper is mainly about the loss on the words level,and analyzes its causes,put forward some compensation methods.
