Why Are Harmonic Analysis and Study Important for Businesses in Brazil?
Harmonics is a crucial topic in a power system since it impacts power quality and the functioning of equipment. High harmonic levels might cause component overheating, hence shortening the lifespan of the device.
The pure sinusoidal wave produced by an ideal power source is distorted by harmonics. Harmonic distortion hinders the production and operations of a business. Here are some commercial impacts of harmonic distortion.
- Harmonics induce extra component losses (Joule effect).
- The existence of harmonics leads to a rise in subscribed power and, consequently, an increase in customer service expenses.
- Oversizing of equipment owing to the shrinkage of the power source
- When the degree of distortion approaches 10 percent, the lifespan of various components is shortened, resulting in a decline in production.
- Harmonics introduce peak currents, resulting in output losses and a significant cost for the time necessary to restore system performance.
Harmonics Motives:
Nonlinear loads that draw current in sudden brief bursts generate harmonics. These pulses disrupt the current waves they produce, which allows harmonic currents to flow across the entire power system. In industrial settings, the presence of harmonics decreases power quality and efficiency. Most organizations have electrical systems that can safely sustain up to 15 percent non-linear loads. If non-linear loads surpass 15%, they may result in negative harmonic distortions. Consequently, it is essential to check harmonic levels to ensure they do not exceed the acceptable limits. Thus, harmonic research and analysis helps to keep awareness of potential dangers and causes, so facilitating the avoidance of harmonic-related issues throughout the design phase and minimizing the likelihood of undesired impacts.
Harmonic Analysis Methodology:
Even though the possibility of harmonic issues is minimal, a timely harmonic analysis must be performed to guarantee that harmonic levels are acceptable. These are the harmonic level progressions:
- Obtaining an electrical one-line diagram and identifying possible nonlinear loads is the initial stage.
- The graphic emphasizes the common coupling’s position (PCC).
- In system buses, plants susceptible to distortion are emphasized.
- All data pertaining to harmonics has been obtained.
- Obtain from utility companies the established PCC values, including the maximum and minimum short circuit fault levels, as well as the acceptable current and voltage harmonics.
- Using publicly accessible software, a simulated harmonic analysis is executed.
- Analyze the harmonics of the electrical system.
- Find the discrete and total discrete distortions of the current and voltage at the buses and PCC.
- Create a spectrum of harmonic frequencies.
- Choose suitable harmonic control measures. Harmonic distortion surpasses acceptable values.
- Repeat the harmonic analysis once mitigating factors have been accounted for.
