“…ITH the increased use of power electronics in residential, commercial and industrial distribution systems, combined with the proliferations of highly sensitive micro-processor controlled equipment, more and more distribution customers are sensitive to excessive harmonics in the supply system [1], some even leading to failure of equipment. Typical power quality disturbances include harmonics, voltage sags and swells, transients and flickers.…”

“…Typical power quality disturbances include harmonics, voltage sags and swells, transients and flickers. End user systems can be sensitive to poor power supply quality, this may lead to malfunction and inefficiency [1]. Many industries are concerned with the operational and financial cost that disturbances in power supply quality can cause and thus there is a growing need for power quality monitoring and classification systems [2] [3].…”

The Hilbert Huang Transform (HHT) is a powerful tool for Power Quality (PQ) classifications. One of the main advantages of the HHT is its ability to analyse non-stationary complex waveforms with very good time resolution. However, like other waveform classification techniques, it has difficulty in resolving the instant of sudden changes in the waveform. It has also difficulty with signals that have frequency components close together. This paper summarises the fundamentals of the HHT technique and its application to power quality classifications including its advantages and disadvantages. Two novel techniques to improve the performance of the HHT technique in analysing power quality problems will be proposed. Results from simulations will be provided and discussed.

“…A PWM based carriagestatic compensator propositions faster response and proficiency for harmonic exclusion. There are three methods of D-STATCOM for power factor correction and harmonic justification based His graphic chart of stage move control is appeared in figure. In this strategy, the pay is proficient by the measuring of the RMS voltage at the heap point, while no interested power guesses are required [7,8]. Sinusoidal signal width balance procedure is utilized with steady exchanging recurrence.…”

Abstract. This paper proposes a new unified active filter to alleviate instantaneous unwanted oscillating powers as they may lead to frequency variations in weak systems. First, the paper presents negative impacts of capacitive loads on the shunt active power filter performance in compensation of instantaneous oscillating real power. Secondly, an advanced universal power quality conditioning system (AUPQS) for three-phase/four-wire systems under non-ideal waveforms is introduced. By considering the suggested compensation algorithm, the AUPQS is able to extremely suppress instantaneous oscillating powers caused by distorted-unbalanced load-terminal voltages. Moreover, an independent single-phase converter is suggested at the load-end in order to regulate the DC-link voltage. Therefore, the instantaneous oscillating powers perfectly suppress and thus, the source-end three-phase currents will be purely sinusoidal. The suggested AUPQS is used to stabilize micro grid frequency. The effectiveness and flexibility of the proposed AUPQS are confirmed by Matlab/ Simulink simulations.
