Disaster Prevention - Generator System Demo
Disaster Prevention is all in the planning
Disaster Recovery is all well and good, as this allows you to re-instate any data which would have ordinarily been lost during a power crash by downloading the stored data from an offsite location
BUT .... wouldn't it be better to prevent the disaaster in the first place? It surely would! Now that's real PowerContinuity.
Disaster Prevention involves being foresighted.
Which parts of your organisation should never lose power?
Then does loss of power include allowing for resilience?
Disaster Prevention really entails expecting a power issue and preparing in advance for the inevitable. Reasonable safety would lead you to the conclusion of installing twin, synchronised generators. Why twin generators? Because, should one generator fail for any reason then the twin will take the load without any loss of power protection.
Disaster Prevention will include N+1 Resilience.
Uniterruptible Power Supplies can be a single UPS or as suggested N+1 is safer and better prepared. In the real world electronic parts can fail.
Disaster Prevention is then the implementation of both UPS Power Systems and Emergency Power Systems working in conjunction with each other.
The UPS Power Systems are operational 24-7 without a break, whereas the standy generators will start up immediately any loss in mains power is sensed. The Uninterruptible Power will bridge the power loss whilst the Emergency Power Generators come up to speed and take the full load. The full load is powered first to the UPS Power Supplies and then on to the A/C and the whole building. All this Disaster Prevention happens automatically from Zero to Hero within 60 seconds.
Below we have illustrated the Disaster Prevention Sequence
NORMAL OPERATION
All Power is received from the National Grid via local transformers
POWER FAILURE
The Load Monitor Panel (AMF) senses a loss of mains power. UPS continues to power the critical load whilst the A/C and lights fail.
GENERATORS START
The Load Monitor Panel (AMF) sends the signal for the generator to start
GENERATORS NOW RUNNING AND BUILDING UP SPEED
The Load Monitor Panel (AMF) waits for generators to reach full speed before re-directing the emergency power to the mains power distribution board.
POWER TO DATA CENTRE
Power to Data Centre, A/C and lights working normally. All building power is restored.
MAINS POWER IS RESTORED & MAINS POWER FAILURE OVER
The Load Monitor Panel (AMF) senses return of mains power. UPS continues to power the critical load whilst AMF instructs the generators to stand down and switch the power from emergency power back to the mains incoming distribution board. Generators continue to run off-load for 5 minutes to cool down. All A/C and lights are back on Grid Supply as well as the whole building.
PowerContinuity Means Business Continuity
