Abstract:The Self Excited Induction Generator (SEIG) is an isolated power source, whose terminal voltage and frequency are controlled by the excitation of capacitance or the load impedance. A new strategy based on an active power filter (APF) for controlling the current and power quality of the self-excited induction generator (SEIG) is also presented in this paper. The proposed active filter proved to play an important role and give good dynamic response and robust behavior upon changes in load parameters. This investigation demonstrated that power average control strategy can facilitate the improvement of the power quality. This control method extracts fundamental (reference) components of the source current for the shunt active power line conditioners for nonlinear loads and unbalanced loads. The shunt APF in conjunction with the proposed controller perform perfectly under different steady state and transient conditions. The simulation results with nonlinear loads and unbalanced loads have showed the effectiveness of the proposed scheme for harmonic reduction in Wind based Power Generation.

“…The bus voltage controller is not the critical part of the control of the VSI because balancing the input and output power is a slow process and the (large) capacitor at the dc-bus serves as a buffer. Therefore it is justified that little attention is paid to the design of this bus voltage controller which can be seen in literature [1][2][3][4][5][6][7][8][9][10]. However this controller can (negatively) influence the behaviour of the VSI.…”

“…Another aspect of the bus voltage controller is the timing of updating the output. The output of the bus voltage controller can be synchronised with the zero-crossings of a phase voltage [1][2][3][4][5][6][7][8][9][10]. This method will result in a step in the amplitude in the other two phases of the injected current if the output is changed due to a transient in the power balance.…”

An important function of the bus voltage controller of voltage-source inverters (VSI) for distributed generation (DG) applications is to control the balance between ac and dc power. Nevertheless is the bus voltage controller not the critical part of the control of the VSI. Therefore it is justified that little attention is paid to the design of this bus voltage controller what can be seen in literature. However, this controller can (negatively) influence the behaviour of the VSI. In three-phase systems a ripple can exist in the bus voltage due to unbalance or harmonics present in the grid voltage or current. This ripple can interact with the bus voltage controller which can have negative consequences on the injected current. Also the timing of updating the output of the bus voltage controller can have consequences on the waveform distortion which can result in oscillations. In this paper the focus is on the timing of updating. An overview of three possible bus voltage controllers is given. The response of the different implementations of dc-bus voltage controllers during a transient is simulated.
