英文摘要：

The impact of traditional three-phase rectifier cimuits on power network was considered. A control method, which based on Space Vector Pulse Width Modulation and a equal power-based detecting method, in shunt active power filter to compensate harmonic component and reactive power component effectively in real time was put forward. The principle of the power-based detecting method was discussed in detail. Compensation control algorithm based on SVPWM was analyzed. The method of voltage vector synthesis was derived. Simulation model of shunt active power filter based on Matlab was given. The simulation model was analyzed. The correctness was verified.
