Compensating For Power Quality Issues Caused by Power Electronics Devices

It is a known fact that there is a growing shift towards renewable energy sources as well as buying and selling electrical power which most often necessitates the use of HVDC transmission systems. Both the solar power generation and HVDC transmission systems make extensive use of power electronics devices. In future, more-and-more grid-forming converters (GFMCs)

Consequence of Weaknesses in Power Quality

In the mid-1980s, I embarked on a mission to resolve persistent “power failure” complaints from the National Accelerator Centre (NAC) in Faure, Western Cape, now known as iThemba LABS—the largest accelerator facility in the Southern Hemisphere. Invited for private tours, I delved into their operations, even entering the high-stakes environment of the operating room. Witnessing

Causes of Unbalanced Voltages and Currents

Practical imperfections which can result in unbalances are: A three-phase equipment such as induction motor with unbalance in its windings. If the reactance of three phases is not same, it will result in varying current flowing in three phases and give out system unbalance. With continuous operation, motor’s physical environment cause degradation of rotor and
