With the development of power electronics technology, direct current transmission and high-power single-phase rectification technology are widely used in industrial sectors and electrical equipment, such as high-power thyristor devices, switching power supplies, variable frequency speed regulation, etc. These typical nonlinear loads will absorb or inject harmonic currents from the power grid, causing voltage distortion, polluting the power grid waveform, deteriorating power supply quality, and increasing additional losses, The transmission capacity has decreased.
In the power grid, three-phase load imbalance, power system resonance grounding, and other factors can generate negative sequence, while high-power rectifiers and nonlinear equipment can generate harmonics. The decline in power quality poses a serious threat to the operation of power supply and electrical equipment. YAC-W6200 is aimed atPower quality monitoringOn the basis of studying and summarizing the characteristics and practical experience of power quality monitoring at home and abroad, a new generation of embedded power quality online monitoring terminal is independently designed and developed in strict accordance with relevant technical standards issued by the country. Adopting a 32-bit DSP processor, it combines functions such as high-speed sampling, calculation, analysis, statistics, communication, and displayPower quality monitoring device。
Baoding Fangchang Power Technology Co., Ltd. was founded in 1980, formerly known as Baoding Computer Factory, Baoding Huaneng Power Electronic Instrument Factory, Baoding Fangchang Power Electronic Technology Research Institute, Baoding Fangchang Power Electronics Co., Ltd., and Baoding Sanyi Fangchang Power Electronics Co., Ltd. In order to cooperate with the implementation of the "Regulations on Technical Supervision and Management of Electric Power Quality in the Power Grid" and the "Harmonics Standards for Public Power Grids" by the State Power Corporation of China, and based on our own development strength, we have closely cooperated with experts from the Department of Electric Power Engineering at North China Electric Power University to develop and produce domestic early stage power harmonic analyzers such as "WXF-1 Microcomputer Harmonic Analyzer", "SXF-1 Double Three Phase Real Time Power Harmonic Analyzer", and "GXF-908Multifunctional power harmonic analyzer"、"DZ-4EPower quality analyzerA series of products. Multiple products have won national and provincial awards multiple times, as well as obtained scientific and technological achievement certificates and national invention certificates.
