Heart of the Telecom Power Plant

SMPS System Concept

These types of power plants did not have the scope for modular expansion,due to which frequent changing of the power plants with each expansion of the switching transmission system was a compulsion.

As compared to convention SCR/Thyristor controlled and ferro resonant power factor the operating characteristics such as transient response power factor efficiency total current harmonic distortion and ripple noise are markedly improved in switch mode power supply plants.

That makes the SMPS based power plants more efficient,economical and reliable for the telecom equipments system.

SMPS based power plants are more compatible with conventional flooded lead acid and VRLA(valve regulated lead acid) batteries.
The batteries are more prone to temperature. It is a known fact that for every 10degree Celsius rise in working temperature over the specified ambient temperature the life of the battery is reduced to half.as most of the SMPS power plants employ micro-processor control techniques the introduction of temperature compensation logic for batteries has became simple and easier.
  

BASIC TYPES OF POWER PLANTS AND SPECIFICATIONS

Classification of power plants(3 piece)

Power plant comprises 3 parts

1. Float Rectifier.
2. Battery Charger.
3. Switching Cubicle.


Power plants are classified in terms of  their capacity..

         Small exchange  Medium exchange  Large exchange            
             power plants        power plants            power plants
Capacity     5/12A              25/5A                         >50A
Input        Single Phase      Single Phase         Three Phase
Paralleling  Not possible    Only manual        Auto paralleling
                                             paralleling is          passible
                                                possible  
                                                   

Another classification of power plant in terms of type

Single unit                   Two unit                             Three unit 
B,R,F,C and SC    one unit is FC/BC/SWC       FR,BC and SC
will be in single    another unit is FR              are in individual units.
