Why Are Harmonic Analysis and Research Crucial for Chinese Businesses?
Harmonics are a significant topic in a power system since they impact both the quality of the energy and the performance of the equipment. High harmonic levels may cause overheating of components and limit the device’s lifespan. Pure sinusoidal waves created by a perfect power source are twisted by harmonics. Harmonic distortion hinders a company’s capacity for production and operation. Here are some economic impacts of harmonic distortion.
- Harmonics lead to increased component losses (Joule effect).
- The existence of harmonics causes an increase in subscription power, which increases customer service expenses.
- Equipment size is excessive owing to a diminished power supply.
- When the amount of distortion approaches 10%, the lifespan of several components is shortened and productivity falls.
- Harmonics introduce peak currents, which results in output losses and dramatically increases the time necessary to restore system performance.

Inspirations in Harmonics:
Nonlinear loads that consume current in irregular, brief bursts generate harmonics. These pulses interrupt the current waves they generate, allowing harmonic currents to circulate throughout the whole power system. In industrial applications, harmonics impair the efficiency and quality of electrical power. Most organizations have electrical infrastructure that can safely manage nonlinear loads of up to 15 percent. Negative harmonic distortions may arise if the percentage of nonlinear loads exceeds 15%. Consequently, it is essential to monitor harmonic levels to ensure they remain within the allowed ranges. Consequently, harmonic inquiry and analysis helps retain knowledge of potential dangers and their core causes, making it simpler to avoid harmonic-related issues throughout the design process and decreasing the likelihood of unintended consequences.
Employing Harmonic Analysis as a Resource:
Despite the minimal chance of harmonic issues, a timely harmonic analysis must be performed to guarantee that the harmonic levels are suitable. These are the harmonic level progressions:
- Obtaining an electrical one-line diagram and identifying any potential nonlinear loads is the initial step.
- The image emphasizes the position of the shared link (PCC).
- In system buses, plants that are susceptible to distortion are emphasized.
- All information pertaining to harmonics has been acquired.
- Obtain from utility companies the established PCC values, including the maximum and minimum levels of short-circuit faults and the current and voltage harmonics authorized.
- A simulated harmonic analysis is conducted using publicly available software.
- Analyze the harmonics of the electrical system.
- Find the bus and PCC’s discrete and overall discrete current and voltage aberrations. Create a spectrum of harmonic frequencies.
- Pick appropriate harmonic control strategies. Harmonic distortion surpasses the acceptable thresholds.
- Once mitigating variables have been accounted for, the harmonic analysis should be repeated.
