INTRODUCTION
After more than 70 years of supplying downtown Metropolis with electricity it is time to
retire the SANDERS69 power plant. The city’s downtown revitalization plan, coupled with a
desire for more green space, make it impossible to build new generation in the downtown
area. At the same time, a blooming local economy means that the city- wide electric
demand is still as high as ever, so this impending plant retirement is going to have some
adverse impact on the electric grid.
PURPOSE AND GOAL OF THE PROJECT
As a planning engineer for the local utility, Metropolis Light and Power (MLP), my job is to
make recommendations on the construction of new transmission lines and transformers to
ensure that the transmission system in MLP system is adequate for any base case or first
contingency loading situation.
It is my job to iteratively determine the least expensive system additions so that the base
case and all the contingencies result in secure operation points. The parameters of the new
transmission line(s) will be derived using the tower configuration and conductor types
available. The total cost of an addition is defined as the construction costs minus the
savings associated with any decrease in system losses over the next five years.
I will be using the PowerWorld Simulator to conduct my studies. Any data assumed or
referenced will be listed in the Appendix for reference. I will use the PowerWorld Design
Case 2 for the purpose of the study. I have been asked to submit a detailed report including
the justification of the final recommendation.

DESIGN ASSUMPTIONS
The following assumptions are made for the purpose of simplifying the analysis:
1. I will only consider the base case loading level given in design Case1. In a real design,
typically a number of different operating points/loading levels must be considered.
2. I will consider the generator outputs as fixed values; any changes in the losses are
always picked up by the system slack.
3. I will not modify the status of the capacitors or the transformer taps.
4. The total system losses will be assumed to remain constant over the five-year period. I
will only consider the impact that new design has on the base case losses. The price for
losses is fixed at $50/MWh.

STEPS EXECUTED
STEP 1: Determining the initial operating point using the base case
Aim: To identify the base case operating point of the system to study the impact of the
disconnected power plant at bus SANDERS69.
Procedure:
1. Load design case 2 in the PowerWorld simulator
2. Initial case has the power plant at SANDERS69 disconnected from the grid
3. Perform the initial power flow solution and determine the system operating point
4. Check whether all bus and line voltages are within the limit of 0.95 and 1.10 per unit
5. Check whether all the line MVA flows are less than 100 % of the limit values
The figure below shows the net system losses to be 13.54 MW, for the base case when
the power plant at SANDERS69 is disconnected from the grid.

Observation:
1. It is observed from the above base case analysis that all the power system transmission
lines and the bus voltages are within the defined voltage limits of 0.95 and 1.10 per unit
2. From Table 1, it is observed that:
The least value of voltage obtained by the transmission lines and buses is
0.98207 per unit
The maximum value of voltage obtained by the transmission line and buses is
1.03 p.u
3. Also from the base case analysis, it was observed that all the power system line MVA are
within the defined MVA limit of 100% as shown in Table 2:
The least % of MVA is utilized by transmission line is 0%
The maximum % of MVA is utilized by the transmission line is 71.5%
STEP 2: Perform contingency analysis on the power system
Aim: To study the impact of any single transmission line or transformer or outage on the
remaining system operation. This procedure is known as (n-1) contingency analysis.
Procedure:
1. Select tools in the PowerWorld simulator window
2. Click on the Contingency Analysis option
3. Note that 57 single line or transformer contingencies are defined
4. Select start run button at the bottom right corner of the display to see the impact of
removing any single element on the rest of the power system operation

OBSERVATION:
1. After performing the contingency analysis, it is observed from the above table that the
power system has 13 contingency violations in the base case when the SANDERS69
power plant is disconnected from the grid.
STEP 3: Finding least cost design to install the new transmission lines and transformers to
ensure that the transmission system in MLP is adequate for any base case or first case
contingency loading situation with the retirement of the SANDERS69 power plant.
PROCEDURE:
1. Determine the parameters (resistance, inductive and capacitive reactance, line
length, GMD, GMR, B and G) of all the transmission lines using the tower
configuration and conductor type, which in this case is Cardinal with a symmetrical
tower configuration, having a spacing of 4m between the conductor strands for a
69KV transmission line and 5m spacing for 138 KV transmission line.
2. After determining the transmission line parameters, I use the available rights-of-
ways data from the table given below to construct the transmission line on the
existing Base case, initially keeping all the circuit breakers open.
3. Once, all the transmission lines have been constructed, I now construct a bus of 138
KV, to upgrade the 69 KV buses: WOLEN69, BOB69,FERNA69, SCOT69 and RAY69 to
the 138 KV buses in an arrangement with no contingency violations.
4. Now, that I have my circuit ready for analysis, I close the circuit breakers for single
transmission lines first, then in the second stage I select a combination of two
transmission line pairs in the order given in the table enlisting the Rights-of-Ways
data.
5. After closing the circuit breakers for the single transmission line and later of the
pair of two transmission lines, I note down the total system losses given by the
highlighted yellow box on the top left corner of the one line diagram for each
arrangement.
6. Next, I perform the contingency analysis on the circuit considered. A contingency
analysis window pops up. I select the Start Run option to perform the contingency
analysis.
7. Within a few seconds, the PowerWorld window displays the number of violations
encountered by the considered system on the bottom left corner of the contingency
analysis window.
8. Once, all the combinations of one transmission lines and two transmission line pairs
have been considered, I now calculate the total cost incurred by the construction of
the pair of transmission lines using the equation:
𝑭𝒊𝒏𝒂𝒍 𝒄𝒐𝒔𝒕 𝒐𝒇 𝒑𝒓𝒐𝒋𝒆𝒄𝒕 𝒂𝒇𝒕𝒆𝒓 𝒊𝒏𝒔𝒕𝒂𝒍𝒍𝒊𝒏𝒈 𝒕𝒓𝒂𝒏𝒔𝒎𝒊𝒔𝒔𝒊𝒐𝒏 𝒍𝒊𝒏𝒆 𝒑𝒂𝒊𝒓( 𝒇𝒐𝒓 𝟓 𝒚𝒆𝒂𝒓𝒔)

− 𝑺𝒂𝒗𝒊𝒏𝒈𝒔 𝒂𝒔𝒔𝒐𝒄𝒊𝒂𝒕𝒆𝒅 𝒘𝒊𝒕𝒉 𝒅𝒆𝒄𝒓𝒆𝒂𝒔𝒆 𝒊𝒏 𝒔𝒚𝒔𝒕𝒆𝒎 𝒍𝒐𝒔𝒔 𝒐𝒓
+ 𝑨𝒅𝒅𝒊𝒕𝒊𝒐𝒏𝒂𝒍 𝒄𝒐𝒔𝒕 𝒐𝒇 𝒊𝒏𝒔𝒕𝒂𝒍𝒍𝒂𝒕𝒊𝒐𝒏

From the calculations, I can now select the most cost effective approach to install the new
transmission line/lines and transformers to ensure that MLP is adequate for any base case
or first case contingency loading situation with the retirement of the SANDERS69 power
plant.

11. Initial Base case system losses= 13.54 MW, which is assumed to be constant
throughout the designing process
CALCULATIONS:
1. Calculating GMR for the Cardinal conductor- Since, radius of the conductor is not
specified in the case, therefore, assuming the GMR from the Table A4 as-
GMR= 0.0403’= 0.4836”
2. Calculating GMD for the symmetrical tower configuration using equation-
GMD =√ 𝒅 ∗ 𝒅 ∗ 𝒅
𝟑
, where d= distance between the conductors.
Here, d= 4m for 69 KV line and d= 5m for 138 KV line
Therefore:
GMD for 69 KV line =√ 𝟒 ∗ 𝟒 ∗ 𝟒
𝟑
= 𝟒𝒎 = 𝟏𝟑. 𝟏𝟐𝟑𝟑′
= 𝟏𝟓𝟕. 𝟒𝟕𝟗𝟔”
GMD for 138 KV line =√ 𝟓 ∗ 𝟓 ∗ 𝟓

3. Inductance for the conductor is calculated using equation
𝑳 = 𝟎. 𝟕𝟒𝟏𝟏𝐥𝐨𝐠 (

) 𝒎𝑯/𝒎𝒊𝒍𝒆 /𝒑𝒉𝒂𝒔𝒆
Therefore:
L for 69 KV line:
𝐿 = 0.7411log(
157 .4796
0.4836
) 𝑚𝐻/𝑚𝑖𝑙𝑒 /𝑝ℎ𝑎𝑠𝑒= 1.8621 𝑚𝐻/𝑚𝑖𝑙𝑒 /𝑝ℎ𝑎𝑠𝑒

𝑿 𝑳 = 𝟐 ∗ 𝝅 ∗ 𝟔𝟎 ∗ 𝟏. 𝟖𝟔𝟐𝟏𝒎 = 0.701 𝛺/𝑚𝑖𝑙𝑒 /𝑝ℎ𝑎𝑠𝑒
𝑋 𝐿 For 138 KV line:
𝑿 𝑳 = 𝟐 ∗ 𝝅 ∗ 𝟔𝟎 ∗ 𝟏. 𝟗𝟑𝟒𝟎𝟏𝒎 = 0.72910 𝛺/𝑚𝑖𝑙𝑒 /𝑝ℎ𝑎𝑠𝑒

9. Assuming Conductance G=0
10. The total cost for the project after installing the new combination of transmission
line and transformer is calculated using equation:

COST CALCULATIONS:
The observation tables above show that there are several combinations of transmission
lines and transformers which result in zero contingency violation. But, the goal of our
project is to determine the least expensive combination with zero violations.
Below are the steps, which show calculations for cases which most likely can be the least
cost combination.
CASE A: COMBINATION OF TRANSMISSION LINES: SLACK138 TO WOLEN69
(TRANSFORMER 187MVA) AND BOB138 TO SCOTT69 (TRANSFORMER 187MVA)
Fixed cost for lines SLACK138 to WOLEN69 and BOB138 and SCOT69= [$200,000 × 2]
Variable cost= [$310,000 × 11.5015 + $310,000 × 8.50]
Transformer cost (Qty:2)= [$1,200,000 × 2]
Bus upgrading cost= [$200,000 × 2]
Therefore, net construction cost= $9,400,000.00
Base case system loss= 13.54 MW
System loss for combination considered= 10.13 MW
Saving= [13.54 – 10.13] × 50 × 24 × 365 × 5= $7,467,900
Therefore Net cost of project= [$7,853,503.465 − $7,467,900]= $193,210.
CASE B: COMBINATION OF TRANSMISSION LINES: BOB138 TO WOLEN69
(TRANSFORMER 187MVA) AND SLACK138 TO WOLEN69 (TRANSFORMER 187MVA)

Transformer cost (One 187 MVA, One 101 MVA)= [$1,200,000 + $950,000]
Bus upgrading cost= [$200,000 × 2]
Therefore, net construction cost= $8,253,000
Base case system loss= 13.54 MW
System loss for combination considered= 10.49 MW
Saving= [13.54 – 10.49] × 50 × 24 × 365 × 5= $6,679,500

Observation:
The above observation tables show all the combinations of single and two transmission line
pairs, of which we find the least system cost to be 10.13 MW for the case with transmission
lines: SLACK138 to WOLEN69(with transformer of 187MVA) and JO138 to SCOT69(with
transformer of 187MVA)PG.24. But from the cost calculations shown above, it can be seen
that the most economical combination of transmission lines and transformers is achieved
for the combination of transmission lines: LYNN69 to WOLEN69 AND SLACK138 to
WOLEN69 (TRANSFORMER 187MVA)
Project recommendations:
After studying the impact of all the possible combinations of transmission line pairs, we
arrived at the study outcome table shown above, which represents all the cases which
result in one or more zero violation scenarios.
By further calculating the total cost of the project for the combinations with zero violations,
it is found that the project case with the least cost is obtained by installing the transmission
lines LYNN69 to WOLEN69 AND SLACK138 to WOLEN69 (TRANSFORMER 187MVA)
With Transformer of rating 187 MVA. This transmission line combination incurs a total cost
of $170,500.
This combination LYNN69 to WOLEN69 AND SLACK138 to WOLEN69 (TRANSFORMER
187MVA) satisfies the two main requirements of our study: (1) To result in zero
contingency violations with the power plant at SANDERS69 disconnected from the grid; (2)
To be the least expensive approach.
Therefore, the least expensive system additions that can be implemented so that base case
and all contingencies result in reliable operation with the SANDERS69 power plant
disconnected is achieved by using the LYNN69 to WOLEN69 AND SLACK138 to
WOLEN69 (TRANSFORMER 187MVA)
