Power back up 1-14052012

  1. 1. UPS SOLUTION FOR HIGHEST POWER PROTECTION AVAILABILITY28/02/2006 Newave SA, Switzerland – info@newave.ch - www.newaveups.com ML3-49 1
  2. 2. PART ONE28/02/2006 Newave SA, Switzerland – info@newave.ch - www.newaveups.com ML3-49 2
  3. 3. DISTRIBUTED PARALLEL ARCHITECTURE DPA “Mission critical applications” require high power availability Critical Application(n+1)- DPA . . .No Single Point of Failure. . .Highest Availability28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 3
  4. 4. DISTRIBUTED PARALLEL ARCHITECTURE DPA Why do we parallel UPS’s ?  For Superior Reliability (Redundancy) The answer to superior reliability requirements for business- critical applications is true redundancy, where all parallel modules equally share the load. If one module fails the remaining modules will continue to provide power protection.  For Power Upgrade (Scalability) To meet the power requirement demands of growing data- centers and telecom systems it is possible to easily reconfigure an existing UPS-power system by simply adding one or more modules.(n+1)- DPA . . . No Single Point of Failure . . . Highest Availabity28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 4
  5. 5. DISTRIBUTED PARALLEL ARCHITECTURE DPA Evolution of Parallel Architecture • Fictitious Parallel Architecture - Hot-Stand-by (Cascade) Configuration • Standard Parallel Architecture - Parallel UPS • Newave‘s Leading Concept - Decentralized Parallel Architecture (DPA)28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 5
  6. 6. DISTRIBUTED PARALLEL ARCHITECTURE DPA Fictitious Availability Hot-Stand-by Configuration Cascade system • Each UPS can support total load • No-load condition for No 2 Mains Mains • Compromise solution - no parallel load By-pass Line sharing • The overload capability is limited by the capacity of one single system = 150% typical • The system must execute 2 by-pass operations under overload conditions in series ! By-pass Line (1) Load28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 6
  7. 7. DISTRIBUTED PARALLEL ARCHITECTURE DPA Standard Parallel Architecture 50% load • Load sharing with two units • Each UPS can support total 100% load load (if redundant) • Full overload capability of 50% load 2 units = 300% typical28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 7
  8. 8. DISTRIBUTED PARALLEL ARCHITECTURE DPA Two different parallel topologies + = Centralized Bypass Decentralized Bypass OR28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 8
  9. 9. DISTRIBUTED PARALLEL ARCHITECTURE DPA Parallel - UPS with Centralized Bypass • Limited extension at high cost • Low Reliability • Extendible only with power interruption • Unit splitting with high costs Single point of failure • Additional cabling and cabinet28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 9
  10. 10. DISTRIBUTED PARALLEL ARCHITECTURE DPA Parallel - UPS with Decentralized Bypass • High reliability • Easy to extend (scalable) • Low cost for power extensions • Easy downgrading from parallel to single version is possible28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 10
  11. 11. DISTRIBUTED PARALLEL ARCHITECTURE DPA Parallel UPS + decentralized By-Pass offers: • Redundant by-pass • Scalability • No single point of failure What about control electronics?28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 11
  12. 12. DISTRIBUTED PARALLEL ARCHITECTURE DPA Parallel-UPS with Centralized Logic: “Master-Slave” • One defined UPS is leader • Logic failure = System failure • One critical UPS Element is not redundant Single point of failure28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 12
  13. 13. DISTRIBUTED PARALLEL ARCHITECTURE DPA Parallel-UPS with Centralized Logic: “Common Box” • Only One Element can decide for all units • Logic failure = System failure C.B • One critical UPS Element is not redundant Single point of failure28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 13
  14. 14. DISTRIBUTED PARALLEL ARCHITECTURE DPA Parallel systems offer increased reliability They still have single failure points It’s the intermediate step to reach redundancy NOT EVERY PARALLEL UPS IS A REDUNDANT SYSTEM!28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 14
  15. 15. DISTRIBUTED PARALLEL ARCHITECTURE DPA “Redundant Parallel Systems” “Redundancy” means: The existence in the system of more than one possibility to fulfil the demanded function - or - the system can afford at least one single failure of any type Redundancy degree is “n+x”: n = number of units / elements to fulfil the demanded function x = number of units / elements which can fail without influence n+1 = one unit / element can fail and the demanded function is maintained28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 15
  16. 16. DISTRIBUTED PARALLEL ARCHITECTURE DPA Example: if the demanded function is fly, redundancy means: • 3 engines can fails and the demended function is mantained REDUNDANCY N+3 • If one wing fails the demanded function is not maintained NO REDUNDANCY Single point of failure28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 16
  17. 17. DISTRIBUTED PARALLEL ARCHITECTURE DPA Redundancy in UPS means Demanded function is supply the load 50% load 100 kVA • Redundancy N+1 Critical load = 100kVA 50% load 100 kVA28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 17
  18. 18. REDUNDANCY IN UPS MEANS Fault tolerance: A fault-tolerant or failure-tolerant system is a system which continues its operation even if one or more parts of the system fail Error masking: Capabilty to mask failures in order to avoid any influence on the demanded function Error detection: A sensor / supervisory-element to detect single failures Error isolation: Capability to isolate faulty parts without disturbing the demanded function28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 18
  19. 19. REDUNDANCY IN UPS MEANS Fault Analysis - part identification: Capability to analyse a failure and identify the faulty part Error removal: Replacement of faulty parts without disturbing the demanded function Return to normal mode: Normal operation will be restored without interrupting the demanded function28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 19
  20. 20. REDUNDANCY IN UPS MEANS •Fault tolerance •Error masking •Error detection •Error isolation •Fault analysis •Error removal •Return to normal mode All these operations must be carried out without putting any strains on the load: !! WITHOUT INTERRUPTION !!28/02/2006 Newave SA – info@newave.ch - www.newaveups.com ML3-49 20
