Why Are Harmonic Analysis and Study Important for Businesses in Argentina?

Since it affects both the quality of the electricity and how well the equipment works, harmonics are an important subject in a power system. High harmonic levels might lead to component overheating and reduce the device’s lifetime.

Harmonics cause the pure sinusoidal wave generated by a perfect power source to be warped. Harmonic distortion impairs a company’s ability to produce and run its activities. Here are some harmonic distortion’s financial effects.

(Joule effect) Harmonics cause additional component losses.
The presence of harmonics causes subscription power to grow, which raises customer service costs.
Equipment size that is excessive due to the power source’s reduction
The lifetime of many components is decreased and productivity decreases when the distortion level reaches 10%.
Peak currents are created by harmonics, which causes output losses and adds significantly to the time required to recover system performance.

Motives for Harmonics:

Harmonics are produced by nonlinear loads that draw current in erratic, short bursts. Because of the interference caused by these pulses, harmonic currents may flow freely across the whole power system. Harmonics reduce the efficiency and quality of electricity in industrial environments. Electrical systems in the majority of businesses can safely support non-linear loads of up to 15%. Negative harmonic distortions may occur if non-linear loads reach 15%. As a result, it is crucial to monitor harmonic levels to make sure they stay within the permitted ranges. Thus, harmonic research and analysis aid in maintaining knowledge of possible risks and their root causes, making it easier to prevent harmonic-related problems during the design phase and reducing the chance of unintended consequences.

Methodology for Harmonic Analysis:

Despite the low likelihood of harmonic problems, it is nevertheless necessary to do a timely harmonic analysis to ensure that the harmonic levels are appropriate. The harmonic level progressions are as follows:

The first step is getting an electrical one-line diagram and determining any potential nonlinear loads.
The location of the common coupling (PCC) is highlighted in the figure.
Plants that are sensitive to distortion are highlighted in system buses.
All harmonics-related data has been gathered.
Obtain from utility companies the PCC values that have been set, such as the maximum and lowest levels of short circuit faults and the permitted current and voltage harmonics.
A simulated harmonic analysis is carried out using software that is available to everyone.
Analyze the electrical system’s harmonics.

Find the current and voltage discrete and total discrete distortions at the buses and PCC.
Make a harmonic frequency spectrum.
Pick appropriate harmonic control techniques. Harmonic distortion exceeds allowable limits.
Once mitigating variables have been taken into consideration, do the harmonic analysis once again.
