KST has been awarded the coveted ECA certification (Enhanced Capital Allowance) for its dynamic UPS KPSâ 500HP.
The purpose of the ECA program, part of the Carbon Trust reduction in CO² emissions, is to reward ‘green’ equipment which meets strict criteria for energy efficiency. The KPSâ 500HP fulfills successfully all these criteria and becomes the first dynamic/rotary UPS to obtain this certification.
Customer Users in the United Kingdom not only benefit from the high operating efficiency of the UPS KPSâ 500HP, but also enjoy significant fiscal advantages upon capital equipment costs.
The module is a stand alone, monoblock machine, using two KST accumulators at each end of a centrally positioned low reactance alternator. All items are directly connected via a flexible coupling attached to each of the two accumulators.
This arrangement allows each Accumulator to deliver only a maximum of 50% torque to the alternator.
For Competitors to achieve similar machine size, they often use two of their accumulators in series with each other (one after the other) and this may be very stressful to the main shaft and its component parts.
The KST E-DRUPS also uses an electric shaft between the prime power genset and the alternator, therefore cancelling any possible problems of excess torque between the genset and alternator.
Grenoble – during March 2009, KST successfully commissioned a high quality power installation for the European Synchrotron Radiation Facility.
Whilst the beam is active, hundreds of researchers from all over the world carry out important tests in many different fields. Such as molecular biology, materials study, biomedical research, nanotechnology, etc. The loss of the beam would lead to the destruction of high technology equipment, the interruption of all research as well as hugh financial costs. In order to avoid this extremely damaging situation, the ESRF acquired a high quality power system called HQPS2 (High Quality Power Supply 2) developed and installed by KS Techniques of Belgium.
After extensive studies, KST designed a system to meet the very strict requirements of the ESRF regarding power supply and efficiency. This system consists of a medium voltage installation at 20 kV of 7 dynamic UPS Rotabloc® KPS-1600-50, protecting a load of 10.6 MW.
The installation has a feature called « Dynamic Autonomy Control » which allows the automatic speed adaptation of the Rotabloc® KPS relative to the load, whilst maintaining the minimum required autonomy and reducing losses.
During a mains cut of long duration, the « Black Out Protection » feature keeps the Synchrotron installation in stand-by mode whilst protecting its vital functions and allowing its quick restart.
Following on from successful tests both on the test bench and in the field KS Techniques are proud to announce the introduction of an "Automatic Lubrication System" to be used in the greasing of the Rotabloc®KPS.
The system comprises of a pump, grease reservoir and a progressive distribution device. The lubricant is distributed between the various bearings via the distribution device and its respective piping system bespoke to the machine design. In addition a flow controller monitors the satisfactory progress of lubrication.
The benefits of the system are:
Bearing greasing is completely under control of a PLC, eliminating the human error factor.
Uniquely each individual bearing is injected according to its specific requirements on a daily basis, providing continuous care.
Cost of maintenance is reduced further because apart from visual inspection manual greasing is totally eliminated.
The Rotary UPS Rotabloc® KPS is, by its very own nature, a simple machine and this can now be further enhanced by the use of the Automatic Lubrication System. The elimination of the human component in the service and operating greatly enhances system reliability.
Datacenters have now evolved to require high performance security solutions coupled with strict demands in power supply quality.
To guarantee a high level of availability and resilience, these datacenters are installing uninterruptible and redundant power supply solutions which keep these centers working irrespective of maintenance works or system failure.
The "Tier" classifications of the Uptime Institute formalize these requirements. In case of an installation Tier 2 or higher, the UPS works with a redundant architecture N+1. The highest security level (Tier 4) defines the redundancy 2 (N+1) or S+S.
KST meets this requirement with the parallel KPS system called Plug&Run.
A UPS system with several dynamic Rotabloc KPS (architecture N+1) equipped with Plug&Run will guarantee a very high efficiency as well as increasing reliability of the whole installation.
For total redundancy and resilience the characteristics of the KPS system are:
No command-master system ("Single point of failure")
No centralized by-pass (second "Single point of failure")
The use of a redundant ring in optical fiber for the communication.
Plug&Run is very flexible and modular therefore making possible easy addition of modules in order to deal with future increases of the critical load. Plug&Run gives the ability to design a project in several phases and consequently to spread out investment costs.
