Re: Em. Gen.
Set
__________________________________________________________
1. 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:
_____________________________________________________
EMERGENCY
LOADS HP KW P.F. KVA D.F. DEMAND
KVA
______________________________________________________
(a).Sum of
incandescent 1.0
lighting loads
(b).Sum of
electrical 1.0
heating loads
©. Sum of
fluorescent
and mercury
loads .9
(d).
Individual motor
loads (2)
TOTALS
Conn. HP:
Conn. KW:
Conn. KVA:
Demand KVA:
___________________________________________________________
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:
(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:
(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
(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:
(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.
