YTPQC-APF in combustion power generation
YTPQC-APF, Active Power Filter reduced harmonic levels results in improved electrical network reliability and reduced operating costs. Nuisance tripping of protective devices and nuisance clearing of fuses due to harmonic heating effects is greatly reduced.
Overheating of motors, transformers, switch-gear and cables is also reduced which increases their life expectancy and reduces maintenance costs. For new installations, over-sizing of distribution equipment to reduce harmonic susceptibility can be reconsidered.
The Background
With the rapid economic development and the rapid expansion of urban scale, urban household garbage has increased day by day, and waste incineration and power generation has also gradually began to be widely used.The main power equipment for waste incineration power generation includes incinerator, bucket, exhaust system and various water pumps, which will produce a large number of harmonic and reactive power in the process of use, which need to be treated.
The PQ Problem
A waste incineration power plant was established in 2004 and mainly operating products include waste treatment, power generation and heating.In the process of production and power generation, the equipment produced a large number of reactive harmonics and 5th and 7th order harmonics, resulting in the decline of electric power quality, the urgent need of treatment.
The Solution YTPQC-APF
The site load mainly includes carding machine, needle acupuncture machine, non-woven oven, coil machine, etc., which will produce a large number of harmonics in the production process, resulting in the field capacitance compensation cabinet can not work normally.In order to ensure the normal operation of the field capacitors cabinet, the 300A active power filter cabinet is installed on site for harmonic mitigation.
The main data before installation of APF, THDi is 16.4%, the main harmonics are 5th,7th order, Power factor is 0.85.
The Technical Performance
For dealing with the reactive power and harmonics at site, install an YTPQC-APF-450A Active Power Filter at site. After installation of APF, THDi reduce to 1.9%, Power Factor increase to 1. The compensation effect is good, which completely solves the reactive and harmonic problems at site.
