Why are Harmonic Analysis and Study so Vital for Finnish Businesses?

Harmonics is a critical issue in a power system because it affects power quality and the operation of equipment. High harmonic levels may cause component overheating, reducing the device’s lifespan. Harmonics corrupt the pure sinusoidal wave produced by a perfect power source. Harmonic distortion impedes a company’s production and operations. Here are some of the business consequences of harmonic distortion.

Extra component losses are caused by harmonics (Joule effect).
Harmonics result in a rise of subscribed power and, consequently, an increase in customer service costs.
Oversizing of equipment due to power source shrinking
When the degree of distortion exceeds 10%, the lifespan of various components is reduced, resulting in a reduction in output.
Peak currents are introduced by harmonics, resulting in output losses and a large cost for the time required to recover system performance.

Motives for Harmonics:

Harmonics are produced by nonlinear loads that draw electricity in short bursts. The power system is filled with harmonic currents as a result of these pulses’ distortion of the current waves. Harmonics have a negative impact on power quality and efficiency in industrial settings. Most commercial electrical systems can safely manage non-linear loads of up to 15%. Non-linear loads that exceed 15% may cause negative harmonic distortions. As a result, it is critical to monitor harmonic levels to ensure they do not exceed safe limits. Thus, harmonic research and analysis aids in maintaining knowledge of potential hazards and causes, allowing the avoidance of harmonic-related difficulties throughout the design process, and reducing the risk of unintended consequences.

Methodology of Harmonic Analysis:

Even if the likelihood of harmonic problems is low, a timely harmonic analysis is required to ensure that harmonic levels are appropriate. The harmonic level progressions are as follows:

The first step is to create an electrical one-line diagram and identify potential nonlinear loads.
The image emphasizes the position of the common coupling (PCC).
Plants prone to distortion are highlighted in system buses.
Harmonic data has been retrieved in its whole.
Obtain the established PCC values from utility companies, including the maximum and lowest short circuit fault levels, as well as the allowed current and voltage harmonics.
Using open-source software, a simulated harmonic analysis is carried out. Analyse the harmonics of the electrical system. the buses’ and PCC’s total and discrete current and voltage distortions.
Make a harmonic frequency spectrum.
Select appropriate harmonic control measures. Harmonic distortion exceeds allowable limits.
Once all mitigating factors have been considered, repeat the harmonic analysis.
