Harmonikakompensation

Harmonikakompensation, also known as harmonic compensation or harmonic correction, is a technique used in electrical engineering to mitigate the adverse effects of harmonics in power systems. Harmonics are non-sinusoidal currents and voltages that result from the operation of non-linear loads, such as variable frequency drives, rectifiers, and arc furnaces. These harmonics can cause several issues, including increased heating, reduced power factor, and interference with communication systems.

Harmonikakompensation involves the use of passive or active filters to reduce the level of harmonics in the system. Passive filters consist of capacitors, inductors, and resistors, and they are designed to resonate at specific harmonic frequencies, absorbing or reflecting them back into the system. Active filters, on the other hand, use electronic components to generate harmonic currents that cancel out the unwanted harmonics in the system.

The benefits of harmonikakompensation include improved power quality, reduced equipment stress, and lower energy losses. By reducing harmonics, the system's power factor can be improved, leading to more efficient use of energy. Additionally, harmonikakompensation can help extend the lifespan of electrical equipment by reducing the thermal stress caused by harmonics.

The design and implementation of harmonikakompensation systems require careful consideration of the specific harmonic spectrum of the system, the load characteristics, and the desired level of compensation. Proper planning and maintenance are essential to ensure the effectiveness and reliability of the compensation system.
