Question

3. Write a sudo-prolog code to protect power system of two generators system.

Answer #1

A power system has two generators with the following total cost
functions:
Generator A: TCA = 5 + 4QA +
QA2
Generator B: TCB = 5 + 2QB +
2QB2
In the total cost functions, Q represents generator output. You
may assume that the generators have no capacity constraints.
Suppose that electricity demand during some hour was 50 MWh and
that the utility running the power system uses economic dispatch to
meet demand. Calculate the system lambda.

Hospitals typically require backup generators to provide
electricity in the event of a power outage. Assume that emergency
backup generators fail
3131%
of the times when they are needed. A hospital has two backup
generators so that power is available if one of them fails during a
power outage. Complete parts (a) and (b) below.
a. Find the probability that both generators fail during a power
outage.
0.09610.0961
(Round to four decimal places as needed.)
b. Find the probability of...

A 10kW power supply system is to be designed. The
following alternatives are available:
1. One single generator of 10kW rating with a failure rate of 0.20
per 1000hr,
2. Two generators each rated for 10kW and with a
failure rate of 0.25 per 1000 hr,
3. Three generators each rated for 5kW and with a
failure rate of 0.20 per 1000 hr.
Which of the alternatives would you select ? Why ? Assume that the
redundant units are statistically...

Two mutually exclusive diesel generators are considered for
purchase by a power generation company. Information relevant to
compare the alternatives is summarized below:
Generator A
Generator B
Capital investment

$80,000
Market value at the end of service life
$35,000
$10,000
Annual fuel and maintenance expenses
$3,000
$5,000
Service life
10 years

Use the IRR method to determine the better machine to be
purchased. The MARR is 10% per year.

Write an LC-3 program (machine code) that compares the two
numbers located in x3600 and x3601 and puts the value 0 in R1 if
the two numbers are equal, 1 if the first number is larger than the
second number, and -1 if the first number is smaller than the
second number.

A rural utility company provides standby power to pumping
stations using diesel-powered generators. An alternative has arisen
whereby the utility could use a combination of wind and solar power
to run its generators, but it will be a few years before the
alternative energy systems are available. The utility estimates
that the new systems will result in savings of $15,000 per year for
3 years, starting 2 years from now and $25,000 per year for 4 more
years after that,...
