In distribution systems, these capacitors provide reactive power to offset inductive loading from devices like motors, arc furnaces and lighting loads. The incorporation of capacitors into a power distribution system offers economical and operational benefits, including increasing system load capacity, reducing losses and improving power factor.
Distribution capacitors can reduce system line losses, as long as the system power factor is not forced into a leading mode. Line losses at 80 percent leading power factor are just as detrimental as line losses at 80 percent lagging power factor.
For compensating reactive power, shunt capacitors are often installed in electrical distribution networks. Consequently, in such systems, power loss reduces, voltage profile improves and feeder capacity releases. However, finding optimal size and location of capacitors in distribution networks is a complex combinatorial optimisation problem.
In the method, the high-potential buses are identified using the sequential power loss index, and the PSO algorithm is used to find the optimal size and location of capacitors, and the authors in have developed enhanced particle swarm optimization (EPSO) for the optimal placement of capacitors to reduce loss in the distribution system.
The incorporation of capacitors into a power distribution system offers economical and operational benefits, including increasing system load capacity, reducing losses and improving power factor. What are the different types of power capacitor units?
Generators provide the reactive needs of distribution plant inductive loads reducing the generator's capacity to produce real power. As will be seen, capacitors will provide improvement on the bulk facilities as a by-product of the improvements they bring about on the distribution feeder.
