Load characteristics
.
The problem of energy consumption in China's sewage treatment plants is very prominent, with huge energy saving potential. Consumption of energy mainly includes electricity, fuel, etc., of which the electricity consumption of 60% -90% of total energy consumption. Pumps, fans as the main load. Motor energy-saving technology occupies an important position in the sewage treatment system. Frequency control technology to change the speed of the AC motor to change the AC motor power frequency is an ideal high-speed governor and energy-saving devices, but a large number of use of frequency converter At the same time also produced a harmonic problem.
.
solution
.
For all low voltage systems, configure the low voltage dynamic reactive power compensation device to absorb the main harmonic components in the system; in the heavily polluted low voltage system, configure the parallel active power filter device; in the key load, configure the intelligent hybrid filter compensation device to To achieve the best governance effect.
