Abstract
To avoid the deficiencies which exist in the single-phase circuit for detecting harmonics and reactive currents, this paper presents a new detecting method after analysing the operating principle of the single-phase shunt active power filter(SAPF). This new detecting method omits the complex coordinate transform of traditional ip-iq detecting method, which can easily obtain sine and cosine signal that in phase of the power supply voltage that do not need PLL circuit. Meanwhile, this new detecting method also proposes the PID negative feedback which can quicken the dynamic response speed. At the same time, this paper also presents a new control method for harmonic and reactive power compensation with an artificial neural network (ANN) controller and a new control algorithm to eliminate harmonics, which makes actual output current of active power filter can accurately track the change of instruction current. Finally, this paper designs a SAPF that compensate harmonics and reactive currents for the single-phase circuit. Through simulation study with Matlab, the simulation results illustrate that the SAPF has a good performance in harmonic suppression and reactive power compensation.
