Description by Manufacturer

Outline

The increasing of nonlinear loads such as computer servers, power supplies, and electronic ballast results in variety of undesirable phenomena in the operation of power systems.

The most important among these are harmonic contamination, increased voltage distortion and power system voltage fluctuations. Harmonic voltage components causes rebooting, power system losses, errors, cause excessive heating machine, can create significant interference on the communication line.

The SPC can monitor and control the active condition of single phase nonlinear load like a data bank and UPS and IT server in real-time. Therefore the SPC can keep up the best power quality of network that correspond to limitation of IEEE Std. 519, AS-2279, EN61000-3-4 and BS G5/4.

Features

Smart Power Conditioner(SPC)

Patent No.0766718 as Single Phase active power filter control device for single phase nonlinear loads
Meet IEEE Std.519-1992
Solve Power Quality Problems
Parallel connection allows easy retrofit for large system
Eliminate neutral zero sequence harmonic current
Modular unit and rack mount expansion

Benefits

Solve a power quality problem
- Reduction of harmonic distortion
- Reduction of peak line current
- Reduction of loss of distribution line
- Prevents overheating in neutral line
- Prevents interference, loss of data in information transmission equipment
- Prevents damage to power sensitive user equipment
Prevents misoperation of breaker
Guarantee safety of power system and reduce cost

Application

Load
Computer server, SMPS, Inverter, UPS, IT equipment etc.

System
Three phase four wire, Single phase 120V~400V, 30A300A

Location
Large computer server center, Data bank, Office, Apartment, Airport, Hospital etc.

Operation

The SPC is single-phase active power filter, which is, applied statistical operation and method of injection current by using DSP. SPC is composed of breaker, power fuse, surge protection circuit, sinusoid filter, capacitor and DSP controller. DSP controller is monitoring a power of non-linear load in real time, estimates the load current harmonics, then using IGBT switching devices injects same harmonic current with perfect phase opposition into the power system. After SPC filter in operation, the voltage and current waveforms of power system become pure sine wave

System Configurations

single phase harmonic filter01

Installation Effects

Keep up the power factor about 100%
ITDD is kept less than 5%
Eliminate neutral zero sequence harmonic current
Prevents flicker and surge
Prevents misoperation of server and UPS
Prevents heating end damage of neutral cable
Prevents damage to breaker, fuse, reactor, capacitor
Prevents sensitive equipment of noise
Increasing the load capability of the transformers
Improve power factor and reduce system loss
Minimize interference with other equipment
