With the deepening of technical supervision of power quality, the increasing implementation of provisions related to power quality in the Electric Power Law of the People's Republic of China, and the promulgation and implementation of governance and punishment measures related to power quality, power quality control has become increasingly important. Electricity quality governance and control are the only means to improve electricity quality indicators, a necessary condition for high-quality power supply and consumption, and a major means of energy conservation and consumption reduction.
The extensive use of power electronic equipment causes severe waveform distortion in the power system, forming so-called harmonics, which damage the quality of power and cause "pollution" to the power grid, thereby affecting power quality and transmission efficiency.
The main way to control harmonic pollution is to install filtering devices at the harmonic source and absorb harmonic currents nearby. The active filtering module is a new type of power electronic device used for dynamic filtering of harmonics and compensating reactive power. It can perform real-time filtering and compensation of harmonics and dynamic reactive power, and is widely used in power, hospitals, metallurgy, petroleum, ports, chemical and industrial enterprises, etc.
SFR-APF active filtering module
01 Advanced design concepts
Real time tracking, dynamic compensation, and the frequency of harmonic compensation can be set separately
02 Modular Design
Users can choose to use 1-5 modules in parallel according to the needs of compensating current, with flexible compensation methods
03 Full battery measurement
The screen can display the operating status of each power module in Chinese; Real time monitoring and recording of equipment operation and fault status
The new generation of power quality management terminal SFR-PQM can seamlessly cooperate with active filtering to achieve remote cloud monitoring and mobile WeChat mini program monitoring.
With the rapid development of modern industry, especially the changes in China's power structure and the increase in load types, various power quality problems such as harmonics and voltage dips are becoming more and more common, which poses great risks to some high-precision and cutting-edge manufacturing industries. The dynamic filtering compensation device, comprehensive power quality compensation device, and active dynamic compensation device in the power quality control device of Jiangsu Sifel Electric can effectively combine relevant problems, achieve the purpose of reactive power compensation and harmonic suppression, and achieve the dual functions of harmonic filtering and reactive power compensation.
