Today market offers different variants of systems which help to solve the problems connected with uninterruptible power supply. Maybe you are already familiar with the alternative technologies – dynamic diesel rotary UPS.
Dynamic UPS demonstrate its advantages in working efficiency, reliability, working lifespan, size in short term and long term electricity supply perspective.
NO-BREAK KS® system construction
Dynamic UPS NO-BREAK KS® represents a single module, which resembles usual diesel-generator set, however it consists of: a diesel engine (produced by MTU, Cummins, Mitsubishi, Deutz) that is coupled to a stato-alternator by electromagnetic clutch. In its turn the stato-alternator is a combination of a kinetic energy accumulator and a synchronous machine.
NO-BREAK KS® system also includes a power panel with choke and a control panel with KS-VISION® touch screen.
Simple but clever system
NO-BREAK KS® is a dynamic system in which uninterrupted power supply is conducted by the alternator. The system operates without using bulky storage batteries and power electronic elements of high capacity.
In conditioning mode, when electricity mains operates within tolerances, an alternator and a choke work as a mains surge filter and maintain on-load voltage within tolerance. The system also reduces mains distortion and improves the power factor in outgoing feeders. As a result, the system supplies perfect sinewave.
In independent mode during mains failure or voltage perturbation, NO-BREAK KS® disconnects the mains power supply and transfers power to the load, until the mains supply returns.
What is the dynamic UPS advantage over the usual ones?
High efficiency – dynamic UPS NO-BREAK KS® is the best performing system, which shows 96% efficiency;Exclusion problems with power supply load – all the disturbances with power supply voltage, such as switching spikes, voltage harmonics, etc. are excluded in all operating modes. power consumption peaks (motor starts, short-circuits etc.) and the harmonic currents caused by the load (in the event of non-linearity) are filtered out by the No-Break KS.
Power factor correction – NO-BREAK KS® system regulates reactive power, which gives an opportunity to control input power factor. This means there is no need for additional power factor correction systems.
The power panel contains the automatic circuit breakers to disconnect from the mains in case of mains failure and transfer to by-pass during some maintenance procedures.
The bearings are not loaded – bearings rotate at relative speed of 1500 rpm, guaranteeing low temperature conditions, high effectiveness and very long lifetimes.
Monobloc design – NO-BREAK KS® system is a Monobloc design; all machines are directly coupled, which makes the NO-BREAK KS extremely robust. The NO-BREAK KS® does not require critical laser alignment inspection in the factory and at site.
Redundant starting system – the NO-BREAK® system is equipped with a redundant starting system by means of an electro-magnetical clutch.
Small footprint – system capacity of 2500kVA (50Hz) allows to save up to 50% floorspace in contrast with static UPS systems.
Various configurations – The NO-BREAK KS® systems can be designed in various configurations, most common are the single and the parallel configuration.
Dynamic UPS model series power can vary from 200kVA to 2500kVA. What is more, power changes in small steps, which certainly is a plus. A customer can find the model that with the power needed.
Method of procedure
In the heart of the NO-BREAK KS®‚ is its kinetic energy accumulator; a clever but simple system to store and retrieve kinetic energy. The kinetic energy accumulator consists of two rotating parts: the outer rotor runs mechanically-free around the inner rotor.The inner rotor, driven by the main shaft, rotates at 1500 rpm (50 Hz) or 1800 rpm (60 Hz). It contains two sets of windings; a three-phase AC winding and a DC winding.
The dynamic diesel rotary UPS secures the critical load against an unlimited number of repeated mains failures. These systems are used by:
