Beijing Gaobeidian Wastewater Treatment Plant

Beijing Gaobeidian Wastewater Treatment Plant

Typical case of harmonic treatment in sewage treatment plant (Beijing Gaobeidian Wastewater Treatment Plant)
Background of the project:
The load of a substation of a sewage treatment plant is mainly composed of 21 frequency converters, and the corresponding motor is driven by the frequency converter. The power distribution is 7 sets of 37kW, 7 sets of 2.2kW, and 7 sets of 1.5kW. Each of them is a group of 7 groups, each of which is one 37kW, one 2.2kW, one 1.5kW, and the system is put into three groups at the same time. Since all are inverter loads, the inverter is a very large harmonic source, which brings serious harmonic pollution and harmonic interference to the system, causing the system to not work properly, and often burns out electrical components, in order to To solve the problem, harmonic management must be carried out.
Governance plan:
According to the information provided by the user, the load can be put into three groups at the same time, then the maximum operating power is (37kW+2.2kW+1.5 kW)×3=122.1 kW, and the harmonic content is about 36 kW, so we choose 50 kW harmonic Wave management device.
Governance effect:
It can be seen from the above data that before and after the active power filter is operated, the grid current changes are very obvious, and the purpose of eliminating current harmonics and improving the power supply voltage is achieved.
