Shunt active power filters (SAPFs) implemented without harmonic detection schemes are susceptible to sudden load variations. This paper proposes a robust control strategy to reduce this drawback. In this strategy, the dc-link voltage is regulated by a hybrid control technique combining a standard proportional–integral PI and a sliding-mode (SM) controllers.(More)
This paper proposes the estimation of active power, reactive power, apparent power, and power factor using the scaling and the wavelet coefficients of the Maximal Overlap Discrete Wavelet Transform (MODWT). The performance of the proposed wavelet-based power measurement was assessed and compared with the IEEE Standard 1459-2010 and the power estimation(More)
The wavelet transform is a powerful tool for real-time detection of transients on synchronous machine terminals which can be used into the control strategy of a power system stabilizer in order to preserve the power system stability. The main goal of this paper is to identify the faster detection of transients in synchronous generator terminals by using the(More)

This paper proposes the comparison of three phase and five phase permanent magnet synchronous motor (PMSM) and also explain the various types of fault accurse in the five phase (PMSM) with pentagon connection. At the end the simulation results are provided for comparison of three phase and five phase current wave form, without fault and with fault also the(More)
