6 FAQs about [Main distribution capacitor]
How to find the optimal placement of capacitors in a distribution system?
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.
How shunt capacitors are used in distribution networks?
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.
Which aspects of the power flow model are important to capacitor allocation?
The aspects of the power flow model which are important to capacitor allocation are: Transmission grid is generally modeled as a swing bus feeding the main distribution transformers. In a relatively large distribution system, single phase feeders are generally lumped and modeled as 3 phase loads and similarly for industrial plants.
How to place a capacitor in an industrial plant?
Place capacitors at loads which consume significant reactive power. For example, place capacitor in an industrial plant which have less than 85% power factor and bus voltage less than 95% nominal. Combination between rule of thumb (so called 2/3 rule) and running series of power flow simulations to fine-tune the capacitor size and location.
What is the objective function of capacitor optimal placement in distribution networks?
The objective function of the capacitor optimal placement in distribution networks is the cost of installed capacitors, installation costs, etc., and the cost of power and energy losses.
How to optimize capacitor allocation in radial distribution networks?
