Why Are Harmonic Analysis and Research Crucial for Korean Businesses?
A power system’s harmonics are essential because they influence the quality of the electricity and how things work. High harmonic levels can reduce the lifespan of equipment components and make them overheat. Harmonics alter the pure sine waves produced by an ideal power source. Harmonic distortion makes it difficult for businesses to produce goods and run operations. Here are a few situations when harmonic distortion affects commerce.
- Harmonics cause components to lose more energy (Joule effect).
- The quantity of power subscribed to increases when harmonics are present. As a result, spending rises, which shows that client services are becoming more expensive.
- Equipment that is too large because the power supply is insufficient
- The lifespan of different components is shortened, which lowers productivity, when the distortion level approaches 10%.
- Peak currents produced by harmonics trip outdated technology, causing output losses and a significant cost for the time required to get the system working again.

Causes of Harmonics:
Loads that do not move in a straight line and draw current in quick bursts cause harmonics. As a result of these pulses, harmonic currents travel throughout the whole power system as distorted current waves. Electricity’s reliability and efficiency in commercial settings are hampered by harmonics. Most organizations have electrical infrastructure that can safely support up to 15% nonlinear loads. Harmonic distortions may be harmful if nonlinear loads account for more than 15% of the total load. As a result, it is crucial to monitor harmonic levels to make sure they do not get excessively high. A harmonic inquiry and analysis may therefore aid in keeping track of potential threats and their sources. This can help to reduce the possibility of unfavorable consequences and aid in the eradication of harmonic-related issues during the design process.
Using Harmonic Analysis as a Tool:
Even if harmonic issues are rare, it is still necessary to perform a timely harmonic analysis to make sure they are not serious. The following are the steps for determining the harmonic level:
- As the first stage, draw a one-line diagram of the electrical system and note any nonlinear loads.
- The image is mostly focused on identifying the connection (PCC).
- System bus plants that are deformed are the focus.
- Harmonics-related information is complete.
- Obtain the PCC values predetermined by the utility. There are allowed thresholds for current and voltage harmonics as well as the highest and lowest short circuit fault levels.
- It uses free software to simulate harmonic analysis.
- Analyze the electricity in the system harmonically.
- Calculate the discrete distortions at the buses and PCC as well as the overall current and voltage.
- Make a harmonic frequency spectrum.
- Choose the appropriate harmonics control techniques. Harmonic distortion is over the limits.
- Once the mitigating measures have been put in place, do the harmonic analysis once more.
