A new control method for active filters based only on voltage detection at the Point of Common Coupling (PCC) is proposed. This technique allows using the active filter as a plug-and-play sensorless device, as it is possible to compensate the harmonics produced by the distorting loads just by measuring the PCC voltage, without needing to measure the distorting load current, and just with an approximate...
Phase locked loop (PLL) algorithms are commonly used to track sinusoidal components in currents and voltage signals in three phase power systems. Despite the simplicity of those algorithms some drawbacks arise when signals have variable amplitude or are polluted with relevant harmonic content and measurement noise. These are typical conditions in aircraft AC power systems, where the fundamental frequency...
A novel algorithm for fundamental frequency and harmonic components detection is presented in this paper. The technique is based on a real-time implementation of discrete Fourier transform and it allows fast and accurate estimation of fundamental frequency and harmonic amplitudes and phases of a distorted and noisy signal with fluctuating fundamental frequency. It is suitable for active shunt filter...
