Nanjing Pukou Waterworks

Typical case of harmonic treatment in waterworks (Nanjing Pukou Waterworks)
Background of the project:
A water power plant is driven by a high-power inverter to drive the water pump motor. Because the high-power diode rectification and high-power thyristor inverter are required in the inverter, the current harmonics are generated in the input and output loops, which interfere with the power supply system, load and other. Adjacent to electrical equipment, affecting the metering work is not normal.
Governance plan:
After field testing and analysis, using one of our 100A active power filters, the harmonics can be well suppressed, and the meter can work normally;
Governance effect:
After the treatment, the harmonics are effectively suppressed, the current waveform tends to be sinusoidal, and the meter works stably.
