With the widespread application of power electronics technology, high-order harmonics generated by nonlinear loads in modern industrial and mining enterprises enter the power system. Causes power supply voltage waveform distortion, reduces power quality, produces electric power pollution, accelerates damage to equipment of power-consuming enterprises, causes low power factor of operating loads, and wastes electric energy.
The existence of high-order harmonics increases the loss of power equipment, increases temperature, and aging of insulation shortens equipment life. High-order harmonics interfere with communication systems, cause malfunctions of electronic protection devices, increase measurement errors, and affect the normal operation of equipment. High-order harmonics may cause system harmonic amplification or even parallel resonance due to unreasonable configuration of the capacitor bank, damaging the power supply equipment, or amplifying the harmonic current entering the capacitor bank, causing the capacitor bank to overload and cause failure.
Installing power filtering devices can effectively absorb high-order harmonics, improve power supply quality, increase power factor, save energy, reduce losses and reduce the load of power supply and consumption equipment, thereby achieving obvious economic benefits.
Equipment introduction
The filter compensation device uses changes in reactive load to automatically determine switching and optimize the input of filter branches to maintain the harmonic filtering and power factor of the system in the best state. The tuned filter branches of various specific frequencies are composed of professionally designed and manufactured filter reactors, filter capacitors, filter resistors, thyristor groups, valves, circuit breakers and other devices. At the resonant frequency, they can form an approximate short-circuit loop for related harmonics and the characteristic harmonics of the harmonic source. Effectively absorb, filter and compensate reactive power to improve the power factor and remove harmonic pollution from the power grid.

Main Features
Using a microcomputer multi-tasking operating system core with strong anti-interference ability, accurate calculation and rapid development of control strategies according to system conditions.
The filter compensation branch is specially designed and manufactured for the user system to eliminate characteristic harmonics such as sub-sub sub-sub sub-sub sub-sub sub-sub sub-subs as required. The filter compensation effect is obvious.
When the device is put into operation, the power factor of the power receiving device is increased to above, which reduces the line loss of the distribution network, increases the load-bearing efficiency of the distribution transformer, optimizes the power environment, and improves power quality.
