At present, the application of power electronic equipment is becoming increasingly common, and power electronic devices are essential in the production process. Such as personal computers, air conditioning equipment, lighting machines, elevators, DC motors, frequency converters, medium frequency induction furnaces, medical machines, etc. The harmonics generated by these nonlinear electrical devices can lead to energy waste, reduced system capacity, accelerated equipment aging, reduced productivity, and faults in the distribution system itself or other equipment connected to the system.
In situations where harmonics are severe, static reactive power generators have become a solution for harmonic control. They use microelectronic software and hardware technology, micro sensor technology, micro network technology, and electrical manufacturing technology to intelligentize them, achieve low-voltage reactive power compensation function, and enable them to work reliably and conveniently with a series of functions such as zero crossing switching, protection, measurement, signal, and online, It is a major breakthrough in low-voltage reactive power automatic compensation and filtering technology
The static reactive power generator is mainly used for reactive power compensation in situations where harmonics are very serious. It can operate reliably without generating resonance, has no amplification effect on harmonics, and has the function of absorbing and eliminating harmonics to a certain extent. The products connected in series with 7% reactors are used in electrical environments with a main harmonic of 5th order, while the products connected in series with 14% reactors are used in electrical environments with a main harmonic of 3rd order.
The static reactive power generator has a filtering function, which can absorb and release harmonics, eliminate the impact of higher harmonics on the capacitor, protect the circuit and capacitor overload, prevent capacitor overheating, aging of insulation medium, decrease self-healing performance, and reduce service life.
There is also a function of no inrush current switching, which works in conjunction with a dedicated capacitor switching switch to ensure no inrush current switching; Protection function: circuit current quick switching, overcurrent protection: capacitor overvoltage and undervoltage protection; Capacitor over temperature, phase failure, and three-phase imbalance protection. When the temperature of the capacitor exceeds 65 degrees, the entire capacitor will be taken out of operation for protection, improving its service life and ensuring the safe operation of the system.
