Abstract：The operation status and measured data of the electrical system in an office building have been investigated to propose prominent problems，such as high capacitive reactive power and high total harmonic distortion in this office building. Then,relevant reasons are analyzed for these problems and specific scheme are proposed to improve power quality. Meanwhile,actual operation data before and after the adoption of the scheme are provided for the office building.

Key words：capacitive reactive power;total harmonic distortion of current;total harmonic distortion of voltage;power factor;harmonics;active power filter;power quality;load
