Power Quality Analysis
Power Quality (PQ) has turned out to be increasingly vital for commercial and industrial
electric power consumers/customers, especially as modern manufacturing & control
process bank on computerized test equipments and these are pretty sensitive to power
system disturbances and interruptions. Consultants at Supreme Technology & Energy
Solutions can offer you solutions to all your power quality issues and get rid of
problems that may be present in a typical power system. Furthermore, we give you
recommendations to guarantee maximum power quality for facilities under renovation
or construction. Power quality concerns can prove a menace as it can affect your
bottom line and business productivity. We at Supreme Technology & Energy Solutions
with years of solid experience under our belt have the expertise, experience and
technology for determining, solving and more often than not, we implement effective
preventive actions. Some of our Power Quality Analysis services including computer
simulations, site surveys and sensitivity assessments of equipment are indispensible
for enhancing performance of power system.
Frequent Power Quality Problems:
With years of solid experience in all types of facilities, we have identified 3
key types of PQ issues that can have real impact on customer operations.
Voltage Sags & Momentary Interruptions: There is increased
sensitivity of power electronic equipment. Add to this the possibility of voltage
interruptions and voltage sags, the combo of which can result in the most perceivable
PQ events. Programmable controllers, office equipments, computers, induction heating
furnaces and adjustable-speed drives can be highly sensitive to these types of events.
Usually, sags come about when the utility power system has temporary faults and
thereby there is a significant fall in the voltage levels. Needless tripping of
sensitive industrial loads can lead to some equipment downtime, dent the bottom
line and lower productivity and this is precisely the reason why equipment sensitivity
to these events is such a crucial factor.
Transients: DC & AC Drives, in addition to other electronic
loads could be pretty sensitive to transient voltages. The devices are built with
tolerance levels that are more often than not, less than other forms of loads including
normal motors. A key concern for transient voltage is the likely utility capacitor
switching transients’ magnification on customer power systems at very low-voltage
capacitor locations.
Harmonics: DC Drives and adjustable-speed in addition
to the switch-mode power supplies can lead to harmonic currents because of their
non-linear characteristics. The combination of harmonic currents and system frequency
response characteristics can lead to harmonic voltage distortion. Some of the effects
of this distortion include capacitor failures, transformer & motor overheating,
increased system loss and control malfunction. These issues are further augmented
by the employment of capacitor banks that could lead to resonance conditions increasing
the harmonic distortion levels. You will find that these banks are generally installed
for the purpose of PF correction, besides freeing up the transformer capacity. When
we need to carry out studies in facility power system, a number of issues have to
be looked into including:
- Transient analysis
- Harmonic analysis
- PF correction
- Voltage variation analysis
- Utility capacitor switching activities
Determining & resolving PQ Problems: Consultants at Supreme
Technology make use of a gamut of tools and techniques to study, find and correct
PQ issues. Field measurements & monitoring are important elements in the process
of problem solving. We make use of a combo of portable and fixed monitoring instruments
to find out and analyze any forms of disturbances on both the side of the meter
and utility, in addition to several major process points and several other places.
This form of field measurements and monitoring is a cog in the wheel which helps
you locate where exactly the occurrence of a problem and find out their potential
causes and possible solutions. We also make use of computer, simulations for utility
service entrance, power system modeling, major systems, backup systems and key connection
points. These simulations could help us perform ‘what if’ analyses to spot out potential
problems and power system susceptibility, in addition to the possible solutions.
We also carry out a verification of the model against the results that were measured.
Our objective is to offer a solution which is cost-efficient, effective without
leading any problems for the utility. Furthermore, we look into a number of corrective
measures such as providing a number of remedial measures such as offering a gamut
of economical options for the purpose of mitigation.
- Uninterruptible power supplies (UPS)
- Protectors or Surge arrestors
- Capacitors
- Backup generation
- Harmonic filters
- Enhanced line insulation
- SMES - Superconducting Magnetic Energy Storage
