Harmonics are a vital component of a power system since they affect the quality of the electricity and how things work. Excessive harmonic levels can cause parts to overheat, limiting the device’s lifespan. Harmonics modifies the pure sine wave produced by a perfect power source. Harmonic distortion impairs a company’s capacity to generate products and conduct business. Below are a few examples of how harmonic distortion affects business.

Components lose more energy because of harmonics (Joule effect).
When harmonics exist, the amount of power subscribed to rises. Costs grow as a result, and customer services become more expensive.
The larger-than-necessary device with an insufficient power source
As the level of distortion exceeds 10%, the lifespan of various components is limited, resulting in a reduction in production.
Harmonics create peak currents, leading obsolete technology to trip, resulting in output losses and a significant cost for the time required to restore system performance.

Causes of Harmonics:

Harmonics are produced by loads that do not follow a straight line and draw current in quick, abrupt bursts. These pulses create distorted current waves, which circulate as harmonic currents throughout the power system. Harmonics affect electricity reliability and efficiency in the industry. The vast majority of businesses’ electrical systems can withstand up to 15% nonlinear loads without a problem.

Nonlinear loads that account for more than 15% of the total load may cause detrimental harmonic distortions. As a result, it is critical to keep an eye on harmonic levels to ensure they do not become excessive. As a result, harmonic study, and analysis help in the detection of possible threats and causes. This can help to eliminate harmonic-related concerns during the design process, lowering the risk of unwanted results.

Harmonic Analysis Methodology:

Although harmonic concerns are uncommon, a harmonic analysis must be undertaken as soon as possible to guarantee that they are not too serious. The stages of the harmonic level are as follows:

The first step is to create a one-line diagram of the electrical system and identify the nonlinear loads that are accessible.
The image is primarily concerned with the position of the common connector (PCC).
There is a focus on plants that distort in system buses.
All harmonics-related information has been acquired.
Get your utility provider’s predetermined PCC values. This section includes the maximum and lowest short-circuit fault levels and allowable current and voltage harmonics.
A simulated harmonic analysis is performed using publicly accessible software.
Perform an electrical system harmonic analysis.
Total and discrete current and voltage aberrations on the buses and PCC.
Make a spectrum diagram of the harmonic frequencies.
Choose the best strategies for controlling harmonics. Harmonic distortion surpasses allowable limits.
After putting countermeasures in place, do the harmonic analysis.
