ECE 451, Fall 2010 Class design project Revision 8, 11/21/2010 The project will require use of the tools learned during the course. The project schedule will have milestones with deliverables due at each milestone as shown below: For item #1, reference section titled “Design Project Technical Details”. You are to run a series of calculations on the defined power system. 1a. Build electrical model of a power system using physical data describing a power system 1b. For a given model, calculate power flow results “by hand” using paper/pencil/calculator Deliverable: hand in neat sketches and calculations showing: 1b-1: for all busses: complex voltages (magnitude & angle), also incoming and outgoing P and Q 1b-2: for all branches/series elements: complex currents, also P and Q losses associated with each series element 1b-3: for all loads: P and Q Due Oct 21 2010 2. For the given model, build model in power flow software (we will be using “Powerworld”), and verify previously-calculated power flow results. Keep in mind that Powerworld may not naturally model the system with inputs as you were given them. ..your goal is to produce a steady state equivalent of the given data and make sure that the Powerworld model matches your given data and the calculated electrical values. HINT: To make things easier, the loads should no longer be modeled as constant current loads, just model them as constant power loads. Deliverable: Email the *.pwb and *.pwd files to me, and email me a brief written report/summary of the verification exercise comparing the hand calculations to the power flow software results Due Nov 9 2010

3. For the third phase of the project, you are to do the following: First modify the system model from the part 2 solution files as specified below in “MODEL CHANGES.” Study the power system’s load flows and voltages under two cases (valley load & peak load). Identify any operating limit violations. Propose one or more change(s) to the system to solve any identified operating limit violations, and model the changes. Your solution should be the most economic solution possible that solves all operating limit violations. While it is not a requirement that your solution handle all possible single point-of-failure contingencies, you can use this as a factor to show how your solution is the best (if a system is designed for single contingency operation, this means that the system should not violate operating conditions if any one component unexpectedly shuts down or disconnects from the system…this includes lines, capacitor banks, and loads.) Write a brief summary of the changes you propose, and why you feel this is the best solution overall. DELIVERABLE: Email the 4 Powerworld files and the brief written summary to the
