How it works : System description

System Description

The NO-BREAK KS® is such a simple concept that one might think of it as a conventional generator-set. It is made up of a Diesel Engine separated/coupled to a Stato-Alternator, via an Electromagnetic Clutch. The Stato-Alternator is the combination of the Kinetic Energy Accumulator and a Synchronous Machine.

 

The NO-BREAK KS® also includes a control panel and a choke/power panel.

 

NO-BREAK KS® Diesel Rotary UPS

 

Description of the Stato- Alternator

The heart of the NO-BREAK KS® is the kinetic energy accumulator; a clever but simple system to store and retrieve kinetic energy.

The kinetic energy accumulator consists of two rotating parts:

1- The inner rotor, which is the main drive shaft, rotates at 1800 rpm (60 Hz) normally powered by the utility spinning the synchronous machine.The inner rotor contains two sets of windings; a three-phase AC winding and a DC winding.  These windings control the energy storage and retrieval of the system.

2- The outer rotor, or drum  spins at a relative 3000 rpm. (See diagram below).  The speed of this drum is controlled by the AC and DC Windings of the inner rotor.

How does it work? - Energy storage 

In conditioning mode, the drive shaft is spinning at 1800rpm, and the AC winding is powered to generate a rotating magnetic field which turns the drum to the maximum speed of 3000 rpm.

The differential speed of the outer drum compared to the inner drive shaft is only 1200 rpm.  This results in a less stressful operating environment for the bearing and results in very long life of the product before major service intervals -10 years.

The  outer drum stores the kinetic energy needed to bridge the time required by the deisel engine to start and connect to the drive shaft.

The kinetic energy accumulator's drum is what makes the system a UPS.  The drums are capable of providing up to 2400kW UPS in a single NO-BREAK KS® module.

How does it work? -Energy retrieval 

When a utility outage occures at the input of the system, the DC winding of the inner rotor is energized and the outer drum is electrically coupled to the inner rotor by an induced field.  The kinetic energy of the drum then "drives" the inner rotor via this induced field.  This energy transfer is regulated by accurately controlling the current injected into the DC winding ALWAYS maintaining the output frequency to 60Hz.

The diesel engine is started and coupled to the inner rotor drive shaft of the system via the electormagnetic clutch.The load is then slowly tranferred to the diesel engine.

The entire energy storage and retrieval system is totally brushless excitation.  Helping to provide a system with very minimal maintenance needs.
