Analysis of Energy-saving Measures in

Harmonic Treatment is a safer, more reliable, and practically significant energy-saving measure with considerable promotion value.

(1) Reduction of electrical energy losses. Harmonic currents in power lines cause additional copper and iron losses in various electrical equipment within the system, such as transformers, transmission lines, power capacitors, motors, and electrical devices. Harmonic treatment can be considered as the generator of harmonics, where harmonic energy is converted from the fundamental wave energy through the nonlinearity of equipment. Harmonic currents are generated by nonlinear loads, then flow into the system and are dissipated in the loads and lines. By installing an APF, the phase line current can be effectively reduced, thereby achieving energy-saving goals.

(2) Benefits resulting from the improvement of power factor. With the widespread use of nonlinear loads (such as frequency converters) in enterprises, the large amount of harmonic current generated causes Reactive power compensation equipment to be unable to switch on or off. Reactive power compensation The inability of equipment to operate normally inevitably leads to a decrease in power factor. Currently, power supply authorities impose severe penalties on enterprises with substandard power factors. While suppressing harmonics, the APF can also effectively compensate reactive power components. Furthermore, compared with the group compensation method of conventional reactive power compensation devices, the APF can dynamically and smoothly compensate or absorb system reactive power, offering technical advantages unmatched by traditional reactive power compensation equipment.

(3) Benefits resulting from the extension of electrical equipment service life. Harmonic treatment can effectively prolong the lifespan of users' electrical equipment. For power supply entities, harmonic treatment can reduce the skin effect of current in cables, thereby lowering network losses and enhancing equipment utilization.

(4) Benefits resulting from the improvement of product yield. For precision manufacturing enterprises, instability in power quality leads to increased product scrap rates. The use of APF can effectively improve power quality and increase product yield.

In conclusion, with societal advancement, the installation of filtering products undoubtedly possesses broad market potential and will yield substantial social and economic benefits.
