Active power filter thesis proposal single- and three-phase systems

[Show abstract] [Hide abstract] ABSTRACT: Selective harmonic cancellation is becoming of primary importance in many of power electronics applications, for instance, uninterrupted power systems, regenerative converters, and active power filters (APFs). Such applications, the main objectives certainly are a precise cancellation of selected harmonics along with a quick speed of response under transients. This paper provides a novel signal-processing formula for selective harmonic identification according to heterodyning, moving average finite-impulse response filters, and phase-locked loop (PLL). The formula may be used within the current in the nonlinear load within the feedforward-based charge of an APF. The PLL tracks the phase and frequency within the fundamental component. Then, the essential phase is multiplied using the order within the selected harmonic, and two random unitary orthogonal axis waves are generated. These unitary waves, rotating inside the harmonic frequency, are multiplied using the input load current, therefore moving the Fourier series coefficients within the selected harmonic to Electricity (heterodyning). Moving average FIR filters are widely-used to filter the harmonics generated within the heterodyning process inside the Electricity signal moving average FIR filters are extremely appropriate for most the power quality applications, because of their comb-type frequency response additionally for their quick transient response. Experimental results confirm good performance for steady-condition harmonic cancellation along with an optimal system reaction to load transients.

[Show abstract] [Hide abstract] ABSTRACT: This paper proposes a repetitive-based controller for active power filters, which compensates selected current harmonics created by distorting loads. The approach draws on the measurement of line currents and performs the compensation of selected harmonics having a closed-loop repetitive-based control plan with assorted finite-impulse response digital filter. In comparison to conventional solutions according to stationary-frame current control, this method enables full compensation of selected frequencies, setup active filter has limited bandwidth. In comparison to synchronous-frame harmonic rules online currents, the complexness within the suggested formula is furthermore to the quantity of compensated harmonics. Additionally, it’s appropriate for digital signal processor implementation and fewer mindful to rounding and quantization errors when finite word length or fixed-point implementation is called. Experimental results round the 5-kVA prototype see the theoretical expectations.

[Show abstract] [Hide abstract] ABSTRACT: This paper handles the implementation in the indirect current charge of a parallel hybrid filter (PHF) system with rectifier load to get rid of generated harmonics. The compensation principle, design, and PHF implementation are discussed in greater detail.

The suggested control boosts the performance within the passive filters (PFs) under unbalanced situations which are existing within the PFs under fault conditions. Additionally, due to limited capacity of current source inverter, the best possible limit for such compensation might be enforced using the suggested indirect current control according to synchronous reference frame employing decomposition of current in synchronously rotating reference frame that is frequently accustomed to handle PHF. The PHF is controlled using decomposition of load and source currents. The implementation within the control plan’s transported on dSpace with digital signal processor for developed prototype within the PHF. PFs are developed according to its operation while using the PHF, and so the total harmonic distortion within the source current could possibly get minimized together with minimized fundamental-frequency current sinking while using filter section. The look remains transported out by genetic formula, which optimizes the answer for multiple constraints. The whole process of the PHF under dynamic change of load can also be investigated through simulations under MATLAB and thru experimentation.
