How to Solve Harmonic Problems?
Harmonic problems encountered in electrical systems can negatively affect energy quality and lead to serious costs and equipment failures.
Harmonic problems encountered in electrical systems can adversely affect energy quality, leading to serious costs and equipment failures. Harmonics are faulty frequency components present in electrical networks that distort the ideal sine wave. Modern and effective methods must be applied to solve these problems.
Sources of Harmonic Problems
The main sources of harmonics are usually associated with the use of high-tech devices and energy-efficient equipment. The following factors can trigger harmonic generation:
- Variable speed drives (VFDs)
- LED lighting
- Electric arc devices
- Computers and other electronic devices
- Industrial motors
Effects of Harmonic Problems
The presence of harmonics not only reduces the quality of energy in the grid, but can also lead to problems such as
- Equipment Failures: Overheating of equipment such as transformers, motors and generators.
- Energy Inefficiency: Losses that cause the system to consume too much energy.
- Voltage Distortion: Voltage fluctuations that prevent the correct operation of sensitive devices.
- Insulator Problems: Premature wear of cables and insulators.
- Industrial communication problems: Stopping instantaneous communication of communication networks.
Solution of Harmonic Problems
The most effective method in combating harmonics is the use of Active Harmonic Filter (AHF). This new generation technology offers a solution by minimising the effect of harmonics in energy systems.
What is Active Harmonic Filter?
Active Harmonic Filter is a device that detects harmonic fluctuations occurring in the network and generates electrical signals in the opposite phase of these fluctuations. In this way, harmonics are neutralised and the energy system operates at optimum performance.
Advantages of Active Harmonic Filters
1. Energy Quality Increase: Voltage and current waves approach sinusoidal form.
2. Equipment Life: Reduces the risk of failure of electrical equipment.
3. Energy Saving: Minimises energy losses with a more efficient network.
4. Easy Installation: Can be easily integrated into the existing system.
5. Flexibility: Quickly adapts to varying load profiles.
Active Harmonic Filter Usage Areas
- Industrial plants
- Shopping malls
- Hospitals
- Data centres
- Airports
Conclusion
Harmonic problems can create serious problems in modern energy systems, but Active Harmonic Filters, an effective method for solving these problems, offer a new generation solution. It is critical to choose this innovative technology to improve energy quality, reduce costs and ensure efficient operation of systems.
