Problem and Report -
A skeleton power system is shown in Figure 1. The equipment specification for the system to be designed are provided in Appendix C. The performance criteria and methods to meet the criteria are provided in Appendix A. Using a power flow program, manual calculations and knowledge learned in class, the power system was designed to meet the criteria while minimizing the cost of equipment and dispatching generation in the most economical manner.
The report is broken into the following sections:
Section 1: Component Models and Parameter Evaluation.
Section 2: Preliminary Base Case and its Deficiencies
Section 3: Series and Shunt Compensation Calculations for the 345 kV line.
Section 4: Justification for Any Added Lines
Section 5: Equipment Schedules and Flow Diagrams.
The sequence of activities used to complete this system design and prepare the final report are given in Appendix B.
Appendix B - Sequence of Steps Used for Completing System Design
1- Make calculations for the system model using 100 MVA base and kV bases of 22 kV, 230 kV and 345 kV.
2- Prepare impedance diagram
3- Prepare data for computer program input
4- Make computer data file
5- Run preliminary base case. (Heavily loaded system.) Hint: You will need to add fictitious generators at buses to get the power flow to solve.)
6- Determine series capacitor requirements for the 345 kV lines assuming you'll need to ship all 600 MW from generators 1 and 2 over one line (one line out) under heavily loaded case.
7- Determine fixed shunt reactor requirements under lightly loaded case to compensate for the Ferranti Effect on the 345 kV lines
8- Determine the need for additional lines or equipment
9- Determine the generator voltage schedules, transformer tap schedules and switched shunt reactor and capacitor requirements for voltage control for base case. (See definition of the base case: heavily loaded etc.)
10- Determine the generator voltage schedules, transformer tap schedules and switched shunt reactor and capacitor requirements for voltage control for lightly loaded case.
11- Fill in the schedule templates for the heavily loaded case with one line out of service and the lightly loaded case.
