As a energy consumer, Do you think, Are you getting a Quality Power 

Do you know the Significance of Quality Power ?

Why Industries are Striving to acheive it ??        

As we know quality is a perception and if consumers are happy with the things / service delivered to them, then one can say that things/service is of good quality. But In respect of electric power, How could we say ? Considering the conditions before about 20 to 30 years back, we had less awareness and information but now, as more and more people are using electrical gadgets, for various reasons, Power Quality is a major expectation from all section of people like Domestic, Commercial and & Industrial Users.
        

What is Power Quality 


" Clean and Stable Power "


The IEEE defines power quality as the ability of a system or an equipment to function satisfactorly in its electromagnetic environment without introducing a intolerable electromagnetic distrubences to anything in that environment.



"Power Quality mainly delas with Continuity of the supply and Quality of Voltage "        

Why Power Qulaity is Importatnt 

Due to immense growth of technology and Manufacturing Processes and tremendous use of power electronics equipment has impacted many loads. As a result, the number of nonlinear loads has increased and is expected to increase dramatically in the years ahead. Which in turn polluting the power quality and creating problems.


Poor power quality can negatively impact industries, data centers, sensitive machinery, small businesses and even households in a number of ways. It can reduce the speed of production, it can damage sensitive equipment, and it can effect efficiency and increase costs. Bad power quality also results in increased energy consumption which is not good for either Utility or Industry Owners.        

How Power Quality can be analysed / What are the various Parameters /measures of Power Quality ?        

Power Quality Analysis by studying Various parameters lik

Voltages dips / Under Voltages

Voltage Swell /Over voltages

Voltage fluctuations and Voltage Interruptions

Transient effects or Surges

Unbalances

Harmonics distortion

Power Factor

The electrical equipment which is sensitive to voltage disturbance and/or generates disturbances itself.

What are Causes of disturbances of Power Quality 


An unstable energy load not only causes electrical and production disturbances, it also wastes energy. This is one of the major problems in the electrical environment. These are the common behaviors that cause problems


Harmonics - Can be caused by Non linear loads or variable speed


Network unbalances &#; can be caused by variations in the load. When the load on one or more of the phases is different than the other, unbalanced voltages will appear.


Transients - a change in the steady-state condition of voltage, current, or both. Transients are important because any power system must be equipped to handle peaks and other short-duration things in addition to the steady state power.


Voltage variations &#; are sags, swells, dips, and brownouts occurring when the line voltage is higher or lower than the nominal voltage for a short period.


Flicker- can be caused by welding equipment, shredders, mills ..etc.,?        

How to overcome power quality issues / What are the types of power quality solutions available on the market today / Power Quality Improvements for Today &#; And Tomorrow 


To Improve power quality in any Facility or Industry, measurement and analysis are the critical first steps in any power-quality improvement program.



There are some corrective equipment options and then offer some suggestions for how to implement a continuous improvement process to take a facility&#;s or Industry power-quality performance to the next level.


Transient effects or Surges : Transient Voltage Surge Suppressors are the best option for protecting against transients in a power system.



Voltage sags and interruptions : Uninterruptible power supplies and other energy-storage options are best for shorter-term sags or interruptions. But back-up generators or self-generation equipment is needed when longer outages are encountered. Ofcourse other Options like static transfer switches and dynamic voltage restorers with energy Storage.


Harmonics : Active Harmonic filters, Passive Harmonic Filters & Hybrid Harmonic filters are the recommended solution for harmonic mitigation which are Present trending in Market.



Power factor : Maintaining unity power factor requires producing reactive energy as close as possible to connected loads. Installing of Capacitors/ Automatic Power factor Correction panels in the network is the easiest and most common way to achieve this goal.?        

Few benfits of sophisticated Power Quality Monitoring 



1. Energy efficiency which Includes reduction of energy consumption, Energy cost optimization and reduction of the cost of energy paid to the Utility.



2. Availability & Reliability, Which minimize the risk of outage, and also sustain an efficient equipment operation.



3. Harmonic management has an impact on all 3 aspects, since it permits



Reduction of the power losses in transformers, cables, switchgear, motors, capacitors.

Reduction of the demand power (in MVA), resulting in lower tariffs.

Use of the total system capacity, without risk of overload, nuisance tripping or premature ageing of equipment. :        

The Importance And Application Scenarios Of Power Quality Analysis

The importance of power quality analysis:
Power quality refers to the quality of AC power supplied to users by the public power grid, caused by terminal loads. Power electronics technology has a positive impact on energy conservation and conversion, but it is also a major source of harmonic pollution in the power grid. The use of various power electronic devices leads to voltage instability, overvoltage, harmonic generation, and serious pollution of power supply quality.
Eliminating the problem of high-order harmonics in the power supply and distribution system can improve the quality of electricity, which has a positive effect and significance on the safety, stability, and economic operation of the power system. Due to the use of electrical equipment by modern industrial, commercial, and residential users, these factors all have the impact of harmonics, electromagnetic interference, and power factor reduction on power quality, which have higher requirements for the standards of power quality. When the power quality of the power grid is disturbed or polluted by the above factors, we need to use professional testing equipment-power quality analyzer to detect it. It can be determined whether it is consistent with the relevant national standards for power quality according to the test results. Then to improve power quality and make targeted improvements to the power grid accordingly.
Application scenarios for power quality analysis:
1. Check if it complies with the IEEE power supply standard to ensure that the power supply to the factory/building/machine is clean.
2. Other algorithms can be used to continuously monitor the predictive health status of memory, heaters, and drivers 24*7 in cloud and edge systems.
3. Compare the energy usage between different machines in the factory.
4. Calculate the utilization and productivity of the machine.
5. Measure the energy consumption per unit of productivity.
6. Estimate the actual electricity cost through an accurate energy usage cost model, which depends on time of day, time of year, etc.
7. Use a time capture mechanism to capture electrical events with small duration of surge cargo in detail.
