Shanghai Nengdu New Energy Co., Ltd. is a high-tech and "Little
Giant" specialized enterprise focusing on power quality treatment
and green new energy technologies. The company’s core products
include Advanced Static Var Generators (ASVG/SVG), Active Power
Filters (APF), Three-Phase Unbalance Regulators (SPC), etc. We
provide low-voltage dynamic reactive power compensation and
integrated power quality solutions featuring millisecond-level
response, stepless continuous compensation, and modular high
reliability. Our products have passed ISO9001 certification and a
number of authoritative third-party tests. With more than 20
patents and proprietary core algorithms, we offer customers
customized solutions to support grid stability, energy conservation
and consumption reduction, as well as efficient grid integration of
new energy.
If you are looking for highly reliable and adaptable harmonic
suppression equipment, Shanghai NengDu is your preferred partner. We have a team of senior power
electronics engineers and a professional R&D and design center
that can tailor active power filter solutions based on your grid parameters, load types, and
iron core harmonic mitigation requirements.
Active harmonic filter (AHF) can eliminate harmonic oscillations
and reduce costs. Active harmonic filter (AHF), as a
multifunctional solution, can be easily customized to provide power
factor improvement, voltage change control, flicker mitigation, and
load balancing functions, greatly improving the power quality in
the network while reducing harmonic pollution.
The active harmonic filter (AHF) is an system designed to eliminate
harmonic oscillations and thereby reduce costs. It can be flexibly
customized to achieve functions such as power factor improvement
and load balancing, which can significantly improve power quality
in power grids.
The active harmonic filter adopts a professional optimized modular
design. The complete system consists of one or more standard APF
filtering modules and an optional intelligent LCD touch screen.Each
APF module is an independent and complete harmonic treatment unit,
capable of stable standalone operation. Users can freely add or
remove modules to flexibly adjust the system’s rated capacity
according to on-site load requirements, without modifying the
original system.It features the advantages of convenient
installation, flexible configuration and strong scalability.
Our streamlined production process delivers both quality and
efficiency:
R&D & Customization: Custom design per project requirements
Material Preparation: Certified components and raw materials
Assembly & Testing: Automated assembly and full performance
inspection
Packaging & Delivery: Export-standard packaging with complete
documents
Q1: How to install and expand capacity?
A: Connected in parallel to the power grid for easy installation;
multiple units can be connected in parallel for capacity expansion.
Q2: Are you a manufacturer or a trader?
A: We are an industry and trade integrated new energy supplier,
specializing in the R&D and production of NengDu Active
Harmonic Filters.
Q3: Is OEM/ODM available?
A: Yes, we support customized LOGO, packaging and functions.
Q4: What is the difference between active harmonic filters and
passive filters?
A: Active harmonic filters feature dynamic compensation, high
accuracy and no resonance risk; passive filters are low-cost but
prone to resonance.
Q5: What effects can be achieved with an active harmonic filter?
A: Reduce harmonic distortion, lower equipment heating, improve
power factor and prevent equipment tripping.
Q6: What is the warranty period of the active harmonic filter?
A: 100% inspection before shipment, with a 36-month warranty
provided.
