FGAPF active power filter (APF) is a new generation of harmonic management solution to dynamically filter harmonics, which adopts advanced dynamic real-time tracking compensation to eliminate harmonics in power grid.FGAPF is a high-power power electronic device based on current detection and current injection technology.By monitoring the current waveform generated by the nonlinear load in real time, the harmonic part is separated, and by controlling the IGBT trigger, the harmonic current of relative size and opposite direction is injected into the grid to filter (offset) the harmonic function, so as to improve the safety and reliability of the electrical system and achieve the purpose of energy saving and efficiency.

Locomotive needs DC power supply, which is a typical nonlinear load. When the locomotive is running, the harmonic voltage and harmonic current are sent back to the power grid through the overhead line.The air conditioning, ventilation, lighting, battery and other electrical equipment of the locomotive are provided by the auxiliary inverter of the locomotive, and the direct current of the locomotive traction is nonlinear load, which also produces harmonics.

The air conditioning, elevator and lighting systems in the electromechanical systems of subway stations are increasingly considering the need for energy saving.The use of a large number of nonlinear power electronic devices, such as variable frequency air conditioning, variable frequency speed elevator, energy-saving lamps, UPS and so on, will produce more harmonics, making the power quality problem of subway stations more serious;According to the analysis of the subway station, the main power quality problems are: harmonics, reactive power, imbalance.Among them, harmonic is the most serious problem.
