Typical connection of Electric Energy Quality Improvement devices


The ideal voltage and current waveforms in power systems are all sine waves with a frequency of 50Hz, but they are widely used in non-linear power equipment (such as high-power thyristors, frequency converters, UPS, switching power supplies, mid-frequency furnaces, and energy-saving lamps), in which a large number of distorted harmonic currents are generated and harmonic currents are coupled to produce harmonic voltages on the line. The Fourier series decomposition is performed on the non-sinusoidal distortion current, where the component of the same frequency with the power frequency is the fundamental wave, and the component of the integral multiple of the fundamental wave frequency is the harmonic wave. This kind of harmonic "pollution" will cause great harm to the power grid and the user, so the harmonic suppression is called a "green project"!




Function description of Electric Energy Quality Improvement devices

a)Output over-limit protection

When the harmonic load capacity exceeds the ANAPF compensation capability, the ANAPF outputs the maximum capacity (that is, the current limit output), which can effectively prevent the ANAPF line from being burned due to the excessive load capacity.


b)Over temperature protection

When ANAPF internal power semiconductor temperature exceeds 85±2°C, ANAPF will automatically cut off the main circuit and generate corresponding fault records on the display HMI;


c)DC bus overvoltage protection

When the DC bus voltage exceeds the set value, ANAPF will automatically shut down and a corresponding fault record will be generated on the display HMI.


d) Input voltage under-voltage and overvoltage protection

When the input voltage is higher or lower than ±10% of the rated voltage, ANAPF automatically shuts off and a corresponding fault log is generated on the display HMI.
