Why Are Harmonic Analysis and Study Important for Businesses in Chile?
Harmonics are an essential topic in a power system, as they affect both the quality of the electricity and the performance of the apparatus.
High harmonic levels may cause overheating of components and reduce the device’s lifespan. Pure sinusoidal waves generated by a perfect power source are warped by harmonics. Harmonic distortion hinders a company’s capacity for production and operation. Here are some economic effects of harmonic distortion.
- (Joule effect) Harmonics induce additional component losses.
- The presence of harmonics causes an increase in subscription power, which increases customer service expenses.
- Due to the diminution of the power source, larger-than-necessary equipment dimensions are required.
- When the level of distortion reaches 10%, the lifespan of several components is reduced and productivity falls.
- Harmonics generate peak currents, which results in output losses and significantly increases the time required to recover system performance.
Harmonics' Motives:
Nonlinear loads that draw current in irregular, brief spurts generate harmonics. Due to the interference caused by these vibrations, it is possible for harmonic currents to travel freely throughout the entire power system. In industrial settings, harmonics reduce the efficacy and quality of electricity. The preponderance of commercial electrical systems can safely support nonlinear loads of up to 15%. Negative harmonic distortions may occur if the percentage of nonlinear loading exceeds 15%. Consequently, it is essential to monitor harmonic levels to ensure they remain within the allowed ranges. Thus, harmonic research and analysis aid in maintaining knowledge of potential risks and their fundamental causes, making it simpler to prevent harmonic-related issues during the design phase and decreasing the likelihood of unintended outcomes.
Harmonic Analysis Methodology:
Despite the minimal likelihood of harmonic issues, a punctual harmonic analysis must be performed to ensure that the harmonic levels are appropriate. These are the harmonic level progressions:
- Obtaining an electrical one-line diagram and identifying any potential nonlinear loads is the first step.
- In the illustration, the location of the common coupling (PCC) is highlighted.
- In system vehicles, plants that are sensitive to distortion are highlighted.
- All data pertaining to harmonics has been collected.
- Obtain from utility companies the PCC values that have been established, including the maximum and minimum levels of short circuit faults and the current and voltage harmonics that are permitted.
- A simulated harmonic analysis is conducted using publicly available software.
- Analyze the harmonics of the electrical system.
- Determine the discrete and total current and voltage distortions at the buses and PCC.
- Create a spectrum of harmonic frequencies.
- Pick appropriate harmonic control techniques. Harmonic distortion exceeds the acceptable thresholds.
- Once mitigating variables have been accounted for, the harmonic analysis should be repeated.
