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

Harmonics is a vital component of a power system since it affects the quality of the electricity and how things work. High harmonic levels can cause components to overheat, limiting the lifespan of the device. The pure sine wave produced by a perfect power source is modified by harmonics. A corporation’s ability to create items and conduct business is hampered by harmonic distortion. Here are a few examples of how harmonic distortion affects business.

  • Harmonics cause more energy loss from components (Joule effect).
  • When harmonics exist, the amount of power subscribed to rises. As a result, costs grow, and customer services become more costly.
  • Larger-than-necessary device with insufficient power source
  • When the level of distortion exceeds 10%, the lifespan of various components is limited, resulting in a reduction in production.
  • Peak currents are generated by harmonics, causing outmoded technology to trip, resulting in production losses and a considerable expense for the time necessary to restore the system’s operation.

Harmonics Leads To:

Harmonics are produced by loads that do not follow a straight line and draw current in quick, abrupt bursts. These pulses create distorted current waves, which circulate as harmonic currents throughout the power system. Harmonics affect the dependability and efficiency of power in industry. The vast majority of organizations’ electrical systems can withstand up to 15% nonlinear loads without problem. Nonlinear loads that account for more than 15% of total load may cause detrimental harmonic distortions. As a result, it is critical to keep an eye on harmonic levels to ensure they do not become excessive. As a result, a harmonic inquiry and analysis can help to monitor prospective threats and causes. This may help to eliminate harmonic-related concerns during the design phase, lowering the risk of unwanted results. 

Harmonic Analysis Methodology:

Even if harmonic concerns are uncommon, a harmonic analysis must be undertaken as soon as possible to guarantee that they are not too serious. The stages of the harmonic level are as follows:

  • The first step is to create a one-line diagram of the electrical system and identify the nonlinear loads that are accessible.
  • The image is primarily concerned with the position of the common connector (PCC).
  • There is a focus on plants that distort in system buses.
  • All harmonics-related information has been acquired.
  • Get your utility provider’s predetermined PCC values. This section includes the maximum and lowest short-circuit fault levels and allowable current and voltage harmonics.
  • A simulated harmonic analysis is performed using publicly available software.
  • Conduct an electrical system harmonic analysis.
  • Determine the total and discrete current and voltage distortions at the buses and PCC.
  • Make a spectrum diagram of the harmonic frequencies.
  • Choose the best strategies for controlling harmonics. Harmonic distortion surpasses allowable limits.
  • After putting countermeasures in place, do the harmonic analysis.
