Abstract:
Unbalanced load condition is one of the major issues of all commercial, industrial and residential sectors. Unbalanced load means that, when different loads are distributed on a three-phase four-wire system, unequal currents pass through the three phases. Due to it, a heavy current flows in the neutral wire, which not only adds the losses, but also puts constraints on three phases’ loads. In this paper, we have presented a practical approach for load balancing. First, we have considered the existing three-phase load system where the supply is a three-phase unbalanced supply.

Abstract:
Non-intrusive load monitoring is a vital part of an overall load management scheme. One major disadvantage of existing non-intrusive load monitoring methods is the difficulty to accurately identify loads with similar electrical characteristics. To overcome the various switching probability of loads with similar characteristics in a specific time period, a new non-intrusive load monitoring method is proposed in this paper which will modify monitoring results based on load switching probability distribution curve.

Cold load pickup (CLPU) is the well-known problem defined as excessive inrush current drawn by loads when the distribution circuits are re-energized after extended outages. During extreme weather conditions, these currents can be high enough to appear as faults or overload. This phenomenon is referred to as cold load pickup because the power supply has been unavailable for a period of time so that the load has reached a “cold” state before being re-energized. It is seen that effect of cold load pickup is more on thermostatic load (refrigerators, air-conditioners, room heaters etc). This paper

Abstract:
To improve the power quality and efficiency on feeding unbalanced loads, this paper proposes a scheme of instantaneous current compensation that can modify the power factor and balance the three-phase currents simultaneously. The method of instantaneous space vectors can compensate the reactive power effectively, but the problems of unbalanced load currents remains. This paper suggests a method that can mitigate the unbalanced load currents by setting the active power as a constant for each cycle. Field measurement data were analyzed. Simulation results confirmed the feasibility of correcting

In this paper, static var compensators (SVCs) and many load compensation techniques are reviewed. A continuously and linearly controlled compensating susceptance is devised from a switched capacitor bank and a switched reactor bank. The switched capacitor bank is built of four binary weighted thyristor switched capacitors, while the switched reactor bank is built of three binary weighted thyristor switched reactors. Although few switched capacitors and reactor are used, their binary weighted values beside their control scheme make them respond as a continuously and linearly controlled reactive

Transporting reactive power from the generating side to the distribution side reduces the transmission line’s capacity to deliver active power to loads. In conventional power systems, during faults or sudden loads, the load flow changes and causes extra voltage drop. Reactive power compensation at the load side can improve voltage quality at distribution busbars, but the conventional compensation method doesn’t offer the required flexibility.
