ABSTRACT
A parameter that allows an evaluation
of power quality transmitted, or distributed, between energy source and the final
user is electric system power factor. Among other aspects, a bigger power factor,
close to unit value, relieves operational conditions of lines and cables, besides,
it improves feeder’s voltage
behavior. Due to load variation along the day, the dynamic compensation of power
factor allows maintaining this parameter close to the ideal. This paper brings a
study about a reactive dynamic compensator based on the voltage control in a capacitive
element, varying the reactive energy in accordance with the system demand, everything
from the energy efficiency point of view. In distribution
systems, the losses due to this variable compensation can be lower than in other
compensation methods and also the voltage presents a better behavior, justifying
its application. the particle abatement technologies, and the electrostatic precipitator with
sufficiently large collection surfaces is able to provide appropriate flue gas
treatment of the particulate matter in the biomass boilers also without
pre-cleaning of the flue gas in multicyclons.
