Real power is the power actually consumed by the load, while reactive power is the power repeatedly
demanded by the load but is returned to the power source and is the cyclic effect that occurs in the
system networks. Power Factor (PF) is one of the first concepts introduced in a basic course on AC.
The Microcontroller detects the amount of power factor correction required and then operates a
capacitor bank to control the power factor with changing load. To browse Academia.edu and the

reduction in power factor is due to the fact that most of the line loads connected in a power system is
inductive in nature and inductive loads are known to reduce the power factor. Capacitor banks are
used to improve the power factor reduced by inductive loads for decades and this paper discusses
the power factor improvements achieved by using capacitor banks. 1. Introduction An AC system is
made up of a lot of components and based on their load consuming nature they can be classified as
capacitive, resistive and inductive. Power factor correction will result in reduction of maximum
demand (KVA or KW) and affect the annual saving over the maximum demand charge. At no load
induction motor has very low power factor. System's performance parameters such as magnetizing
current, armature reaction, leakage reactance, air gap length, machine rating, voltage regulation,
efficiency and so on are adversely affected by its power factor (p.f). Power factor changes according
to loads on a system. The technology needed for this is high power electronics with. Also some
expenditure will be incurred annually in the form of the interest and depreciation made over the
power. If connected to a source of power it can also provide active. When power factor is improved,
automatically energy will be saved A power factor is the goal of any electrical utility company since
if the power factor is less than one, they have to supply more current to the user for a given amount
of power use. To browse Academia.edu and the wider internet faster and more securely, please take a

the time as equipment is switched on and off. Thus consumers having low power factor have to pay
more for the useful power they use making power factor improvement a necessity. 1 STUDENT

are as follows. Both the magnitude and the phase angle of the voltage can. As power factor is one
amongst the prevailing concerns in electrical industries, a striking balance (corrective measures) of

PDF View PDF Power Factor Correction Using PIC Microcontroller Ganesh R Kalokhe;-In recent
years, the power quality of the ac system has become great concern due to the rapidly increased
numbers of electronic equipment, power electronics and high voltage power system.
Due to the fact that most of the electrical loads are inductive in nature and to provide reduction in
distribution losses and the electricity bill charges, a form of power factor correction device is
employed, usually in the form of capacitors, which draws leading reactive current to neutralize as
much of the lagging reactive component of load current as possible. The research was conducted at
the Laboratory of the Electrical Engineering of Institut Teknologi Padang. In this paper, the effects
of low power factor on main motors which use in AL-Najaf cement plant analyzed, such as raw
material mill, cement mill and the clinker cooler. With the Information Age in full swing, the growth
of. So it is necessary to find out the causes of power pollution and methods must be adopted to
minimize the same. The object used in this research was the 3-phase induction motor of 1.5 HP,
220V, ?, 2.75A, 4 poles, 50 Hz, 1400 RPM. And many different techniques have been used to
improve the stability. To improve the power factor in machine tools industries, it is required to install
capacitors of appropriates ratings as near to the load as possible. The WOA algorithm is tested on
IEEE 15, 33, 69 and 85-bus test systems. The results obtained by the proposed WOA algorithm was
compared with different types of DGs and other evolutionary algorithms. When compared with
other algorithms the WOA algorithm gives better results. User loads change all the time as
equipment is switched on and off. Therefore, the question of power factor immediately comes into
picture. So it is necessary to find out the causes of power pollution and methods must be adopted to
minimize the same. The Microcontroller detects the amount of power factor correction required and
then operates a capacitor bank to control the power factor with changing load. Low power factor is
corrected with the most effective Costum Power Devices, namely Static Var Compensator (SVC)
and Static Synchronous Compensator (STATCOM). If connected to a source of power it can also
provide active. For large Industrial consumers this might be a meaning of huge financial impact. In
the wake of identifying poor power factor, automatic power factor control framework switches one
capacitor at any given moment out of a gathering of eight capacitors ( Tiwari and Sharma, 2014).
They make a low-impedance way to ground giving innate self-insurance to lightning surge streams
and some security from surge voltages consequently, working without surge arresters. The motor
could operate with power factor close to unity, higher speed and better efficiency. Articles Get

conditions for a supply system from engineering and economical standpoint, it is important to have
power factor as close to unity as possible. It's like a masterclass to be explored at your own pace. An
assembly of number of capacitors is a capacitor bank and are used to generate kVAr in- order to
improve power factor ( Ramzan et al, 2016). An induction generator must be excited with a leading
voltage; this is usually done by connection to an electrical grid, or sometimes they are self excited by
using phase correcting capacitors. The realization of such an overall system optimization control.

for high recurrence streams thus they can be utilized as channels in frameworks. The technology
needed for this is high power electronics with. These devices constitute an emerging technology
called FACTS (flexible alternating current.
In case of purely resistive load the current and voltage are in phase but most of the loads connected
in any facility is inductive in nature and in case of inductive loads the current lags the voltage and is
therefore out of phase whereas, in case of capacitive load the current leads the voltage (Stokes,
2008). Power factor correction will result in reduction of maximum demand (KVA or KW) and
affect the annual saving over the maximum demand charge. Low power factor is not that quite a bit
of issue in private homes it does however turn into an issue in industry where numerous expansive
engines are utilized. Induction generators are useful in applications such as mini hydro power plants,
wind turbines, or in reducing high-pressure gas streams to lower pressure, because they can recover
energy with relatively simple controls. In any case, the dissemination of inrush streams and music
may cause fizzling and over operation on defensive transfers and wires. ? Ungrounded Wye -

Most of the commercial and industrial installation in the contry has large electrical loads which are
severally inductive in nature causing lagging power factor which gives heavy penalties to consumer
by electricity board. The research was conducted at the Laboratory of the Electrical Engineering of
Institut Teknologi Padang. Thus the overall power factor of industries are very low due to the
increased intake of reactive power by the inductive loads Embedded technology comes into picture
for the very first time when we are thinking about any programmable device for power factor
improvement. An induction generator must be excited with a leading voltage; this is usually done by

of load increases then the reactive power requirement increases which in-turn increases the kVA
demand for the same kW load (Stokes, 2008). The series Controller could be variable impedance,
