Many SMBs often struggle with problems relating to UPS and IT assets due to the sheer amount of time and resources required to run effectively.
Loads and generators causing harmonic distortion have traditionally been modelled as current sources. This model made it reasonable to apply distortion contribution limits in terms of harmonic current injected at point of connection. However, recent experiences have shown that inverter-based devices cannot be modelled as a current source without a shunt impedance. Therefore, the determination of the interaction of the grid and harmonic source must consider the impedances of both sources. Amplification of background voltage distortion due to the connection of new plants therefore may become sig...
This work includes a thorough examination in order to design a novel hexagon-connected autotransformer for a 44-pulse AC-DC converter fed vector controlled induction motor drive (VCIMD). Two paralleled twenty two-pulse AC-DC converters, each with an eleven-phase diode bridge rectifier (DBR), constitute the proposed converter. The system’s performance is evaluated in MATLAB/Simulink environment under various operating conditions of the VCIMD. Traditional 6-pulse converter fed VCIMD suffers from power quality problems. This work intends to alter the design of the suggested autotransformer to m...
Voltage rise caused by high levels of distributed generation is manifesting as voltage regulation challenges for many electricity network operators. In this environment it would be ideal to reduce supply voltage magnitudes, however, many network operators are hesitant to do so due to concerns related to appliance operation at reduced voltage magnitudes. Voltage regulation requirements are defined by network standards and network service providers must ensure voltages remain within specified limits. Through an extensive evaluation of domestic appliance performance when supplied at various volta...
