GENERAL
The
intent of this Design Guide is to outline the procedure to follow in designing
standby power plants for use as an alternate source of power in the event of
failure of the normal electrical service. It does not cover other alternate
sources of power which may be required or permitted by Code (i.e., battery
system, tapping ahead of main switches of two separate services, etc.). Costs
are also not included as they will vary with each project.
2.
CRITERIA
a.
Tabulate the
load which is to be on the emergency system. Include the following:
(1)
Minimum
emergency loads required or recommended by Code:
(2)
Emergency
loads required for standby power plant auxiliary equipment, including:
(3)
ADDITIONAL
EMERGENCY LOADS REQUESTED BY Owner.
(4)
Additional
emergency loads recommended by Consultants, PPC/ADSC and approved by Owner.
b.
List the sum
of loads from 'a" above as follows:

___________________________________________________________
Notes:
(1)
Power
factors for motors normally vary from .80 to .95.
(2)
List only
the largest motors that are to operate on emergency simultaneously.
(3)
HP x .746/
Motor Efficency = KW; KW/P.F. =KVA;
KVA x
D.F. = Demand KVA
P.F.
(System) = KW ( Conn.
)/ KVA ( Conn.
)
c.
Using the
demand KVA and system power factors obtained in 'b" above, select the
generator as fellows:
P12 OF
16.
(1).
Add spare (as required).
(3)
Subtract
any loads included in 'b' which will be put on emergency manually only when the
load conditions allow it (selective loading).
(4)
Select next
higher size generator (continuous rating) available from at least three of the
base bid manufacturers listed.
(a)
Ideal.
(b)
Electric
Machinery
(c)
Delco.
(d)
G.E.
(e)
Century.
(f)
Westinghouse.
(5). Using selected generator, calculate voltage dip due to
starting of single motor, ( or simultaneous starting of group of motors) with
largest locked rotor KVA. Use manufacturer's tables for calculating dip. If dip
exceeds 5%, recalculate based on next higher generator size or investigate use
of reduced voltage starters on the motors.
(6). Determine generator output voltage by weighing the
following factors:
(a)
Normal
operating voltage(s) of equipment on emergency.
(b)
Cost, space
and weight of transformers.
(c)
Cost of, and
spare required for , distributing wiring.
(7). Size generator 3 phase main fused switch or circuit
breaker as follows:
P13 OF
16.
(a)
Continuous
current rating:
I = KVA
Gen./(1.732 x E Gen. Line to Line)
(b)
Interrupting
Rating: Determine from generator manufacturer maximum three phase fault current
available and rate accordingly.
(8). Generator grounding : For normal applications , directly
grounded wye connection and frame of generator to cold
water main or driven ground rods. Where generator line to
ground fault current exceeds three phase fault current
either:
(a)
Specify
generator capable application of withstanding greater fault current and
increase interrupting rating of generator main fused switch or circuit
breaker accordingly, or (P12 OF 14).
(b)
Furnish a
low-value reactor or resistor in ground conductor which will limit line to
ground fault current to a value between 25% and 100% of three phase fault
current.
(9)
Check Code
regulations on generators:
(a)
Taichung, Taiwan: Article ?
(b)
Taiwan : NFPA # ?,
Article ?
(c)
National:
NFPA #? , Article ?
d.
Select
engine as follows:
(1)
Determine
type of engine and fuel to be specified, using the following as a guide:
P14 OF
16.
(a). Diesel engine: Most commonly used, most familiar to
maintenance engineers, large selection of sizes. Howerever, require inertia
block. Specifify at highest speed available in order to reduce weight weight
and cost. Specify for use with #2 diesel oil (lowest sulphur content fuel
commonly available).
(c)
Gasoline
Engine:
(d)
Natural Gas:
(e)
Turbine:
(2)
Determine
basic engine BHP required for selected Generator units.
