  • development of an Instantaneous Real Power tracking control scheme for a single phase grid tied photovoltaic inverter with minimum dc link capacitance
    International Symposium on Industrial Electronics, 2012
    Co-Authors: Chingming Lai, Yihung Liao, Liangrui Chen
    Abstract:

    In this paper, an Instantaneous maximum Power point tracking (MPPT) control is first adopted to achieve fast tracking response for the photovoltaic (PV) Power generation system. Then an Instantaneous Real Power tracking control is proposed to overcome the dilemma of the inherent double line frequency ripple without adding an additional circuit so that one can replace the large electrolytic capacitor with small bipolar film-type capacitors to achieve longer lifetime of the single-phase grid-tied inverter. Furthermore, the mathematical model of the PV system is derived and the minimum capacitance for a specified allowable DC-link capacitor voltage swing is obtained. Finally, simulation results are given for verifying the feasibility of the proposed control strategy.

  • A novel adaptive-fuzzy hysteresis current controller-based active Power line conditioners for Power quality enhancement
    International Journal of Power Electronics, 2013
    Co-Authors: P. Karuppanan, Kamalakanta Mahapatra
    Abstract:

    This paper presents a three-phase shunt active Power line conditioner (APLC) for harmonics and reactive Power compensation to enhance the Power quality. The compensation process is based on sinusoidal extraction control method, which consists of positive-sequence voltage detector to regulate the distorted supply voltage and Instantaneous Real-Power for fundamental component extraction from the distorted line current. The voltage source inverter (VSI)-based active filter switching pulses is generated through adaptive fuzzy hysteresis current controller (HCC). For the adaptive-fuzzy-HCC, bandwidth is calculated without precise knowledge of the APLC parameters (interface inductor and DC-link voltage), the hysteresis band value can be implemented with a fuzzy logic. A comparative assessment of fixed-HCC, adaptive-HCC and adaptive-fuzzy-HCC is carried out. The shunt APLC system is validated through extensive simulation under distorted supply voltage and non-linear load conditions.

  • Cascaded multilevel inverter based active filter for Power line conditioners using Instantaneous Real-Power theory
    India International Conference on Power Electronics 2010 (IICPE2010), 2011
    Co-Authors: P. Karuppanan, Kamalakanta Mahapatra
    Abstract:

    This paper presents a three-phase, five-level cascaded multilevel voltage source inverter based active filter for Power line conditioning to improve Power quality in the distribution network. The active filter compensates both reactive Power and harmonic currents drawn by non-linear loads; additionally it facilitates Power factor corrections. The compensation process is based on concept of p-q theory. However, in the proposed approach only calculation of Real-Power (p) losses are conducted. This method is simple and different from conventional methods; it provides effective compensation for harmonics. The cascaded multilevel inverter switching signals are derived from the proposed triangular-sampling current controller that results in a good dynamic performance under both steady state and transient operations. The dc-bus capacitor voltage of the cascaded inverter is controlled and reduced ripple voltage using PI-controller. This proposed cascaded active Power filter system is validated through extensive simulation under transient and steady state conditions with different non-linear loads.

    2011 Annual IEEE India Conference, 2011
    Co-Authors: P. Karuppanan, Kamalakanta Mahapatra, Rajesh Kumar Patjoshi, Ajay-d-vimalraj
    Abstract:

    This paper presents a cascaded multilevel Voltage Source Inverter (VSI) based three-phase shunt Active Power Filter (APF). The active filter is applied for Power quality enhancement in the distribution grid in terms of harmonic compensation. The compensation method is proposed by sinusoidal extraction controller, which is comprised of positive-sequence voltage detector and Instantaneous Real-Power theory. This approach is different from the conventional methods and provides good compensation characteristics in steady state as well as transient states. Five-level cascaded inverter switching signals are generated from triangular-periodical current controller method. The shunt active filter system is investigated and verified in terms of order of harmonics, V DC settling time and parameters under different non-linear load conditions.
