Power Quality—An Overview
In the latest version, power quality has become a
serious as well as an essential concern for both electricity providers and the
customers consuming it. In the version of customers, the economic impact of
power disturbances can assort from several hundred dollars for repairing or
replacing home appliances to millions of dollars in making losses. Thus, for
utilities, system disturbances can lead to customer dissatisfaction in the
future and revenue losses for the power quality equipment market. The Power
Quality Measurement Equipment Market size is projected to reach USD 44.37 billion by 2025, with 6.26% CAGR
from 2019 to 2025.
Power Quality—It's
Meaning?
Power Quality mainly refers to the quality of the
power or mentioned explicitly, like the current and voltage provided to the
customer. The power is to be provided in clean sinusoidal waveforms at a
frequency of 60Hz that do not contain sags or spikes, which allows every
customer’s equipment to operate consistently.
As per the increasing demand for power quality as
well, its rapidly spreading market has resulted in creating vast importance,
which this article has covered in a précised way. Before starting with
describing the importance of power quality equipment, let us understand the
impact of poor quality of power—
Impact of Poor Power
Quality
Poor power quality can be described as an event that
is related to the electrical network, which ultimately results in a financial
loss. There could be possible consequences of poor power quality can
consequence in:
• Unexpected
power supply failures
• Equipment
failure or faulty
• Equipment
overheating and leading to a lifetime reduction
• Increase
of system losses as well as line losses.
• Damage
to sensitive equipment like control systems
• Interferences
in electronic communication
Importance of Power
Quality
Power quality is simply termed as the interaction of
electrical power with electrical equipment. If electrical equipment operates
accurately and reliably without being damaged, it would be considered that the
electrical power is of good quality. Several power quality issues, as well as
poor power factors, electrical harmonics, voltage instability and imbalance,
influence the efficiency of electrical equipment. Thus, resulting in some
consequences, this includes:
• Usage
of higher energy and costs
• Higher
maintenance costs
• Equipment
instability and failure
As a result of all, energy management is an
essential consideration for any business, and power quality and its equipment
must be assessed as part of any energy management strategy.
Importance of Measurement
of the Power Quality Equipment Installation
Since electrical energy is the thumping heart of the
industry, commerce, and development, maintaining a quality status in the flow
of electricity is imperative. It is highly essential to have measures of Power
Quality equipment in determining influential risks and possible defects in
electrical installations. In fact, the high quality of electrical energy is
achieved only if these conditions are met in a synchronized way. The
requirements are— a good initial design of equipment, effective corrective
action, frequent monitoring and proper maintenance of electrical assets
installed.
Applying Power Quality
Equipment for Monitoring
Modern power quality equipment offers information
that is considered as a benchmark for the overall system performance of power.
This also provides assessment in preventive maintenance, monitor, assess power,
performance and sensitivity of the equipment, and improve energy rates. A
network of power quality equipment can be installed on supply systems, and
their raw measurement data can be aggregated to associate and facilitate to
identify sources of disturbances. Power quality can also be a part of embedded
equipment design for rough integration as well as control. If the equipment has
already been deployed in a factory environment, the power quality profile can
be used to conclude the best mitigation techniques. Therefore, the conclusions
from data analysis and diagnostics can afford reliable input to design
next-generation protection terms and products to improve power quality.
According to the study published by the National
Load Despatch Centre (NLDC), Hydel power generation rose by 30% to 465 million
units a day in 2019. Hydel, solar, and wind power generation touched entirely
of 831 million units, which is equivalent to 10 GW of power and registered a
near 40% growth. This displays that the demand for power has improved over the
years.
In Conclusion
The overall energy demand worldwide is now estimated
to expand at a higher rate annually than the previous time. The magnitude and
complexity of power quality equipment connected to the grid will cultivate and
power quality disturbances will swell proportionally. Modern businesses will
produce increasingly dependent on electrical energy that is reliable and
readily available. Therefore, by using next-generation power quality equipment
technology, industrial equipment owners can look ahead to see and get benefit
from clean power.
