An increasing number of loads are non-linear, introducing harmonics into the power grid and thus significantly impairing the power quality. SFR-APF is an active harmonic filter that effectively reduces the unwanted harmonics.
Linear loads have become a rarity in industrial plants, office buildings, data centers or even private households. Non-linear loads, by contrast, have become increasingly common: frequency converters in drive systems, the large numbers of switch-mode power supplies used in IT and communications equipment, and also more and more in household electronics. Even lighting technology employs mainly non-linear power supplies.
Elecnova active power filter is mainly composed of incoming line contactor, filter, IGBT inverter, and control and protection. The control system of the active power filter detects the current on the load side and the system voltage at the connection point in real time, calculates the current required for harmonic compensation, and controls the three-phase IGBT inverters to give current tracking and compensation orders to suppress harmonics on the load side. Besides, the filter is also capable of protection against AC overvoltage/under voltage, output overcurrent, DC overvoltage/under voltage, short circuit of inverter, and overheating of inverter.
