5. Transient analysis with a classical generator model will be studied next for a three-phase bolted fault at bus 2. Assume the system is in its original state with bus 2 PD=720 MW, QD=252 Mvar and PG3-520 MW before the new line was installed. Using the following parameters for the GENCLS model, G1: 400 MVA, H=1, D=1, Xd'=0.24 G3: 800 MVA, H=12, D=1, Xd'-0.24 determine the critical clearing angle, if any, that causes generator 1 to lose synchronism with generator 3. Consider G3 with its large inertia to be similar to an infinite bus. Load the DesignProject GENCLS auxiliary file using PowerWorld's Add Ons: Transient Stability button near the top of the window. Note: you must be in "Run Mode" to select "Transient Stability". Use the "Load All Settings From" button in the lower lefthand corner to open the menu. Choose "Load Auxiliary..." and then select the proper AUX file. Modify the "Time (Seconds)" field in the "Transient Contingency Elements" record in the lower panel to control the time instant that the fault is cleared. (a) Use the formulas given in lecture to determine the critical clearing angle for generator 1, if any, using the internal power angle for generator 3 as a reference, similar to an infinite bus. (b) Use PowerWorld to determine the clearing angle that causes generator 1 to hit the highest angle it can without losing synchronism with generator 3. When you find the largest clearing angle, capture the generator power angle plot (not the rotor angle plot) by first clicking on the small triangle in the lower righthand corner of the plot window, and then selecting the "Export Chart..." option. (c) Compare the results from your formula-based calculation and the PowerWorld simula- tion.

2. Suppose the bus 2 load increases by 25% at constant power factor, i.e., matching the power factor of the original load. As the loading increases on the lines supplying bus 2, the system becomes less secure under line outages. A new 345 kV line is proposed to supply power to bus 2, either from bus 4 or bus 5. Assume the new line will be fully transposed on a sequence of tower structures with GMD of 8 m. (a) Determine the conductor type based on the costs shown below and the Appendix in the textbook. (b) Consider the possibility of using a bundled conductor configuration. If bundling is chosen, assume a bundle spacing of 0.4 m. Note: the cost of each additional conductor in a bundle is half the cost per km shown in the table below, i.e., the first conductor would be charged the full price, while the second, and subsequent, if any, conductor would be charged half price. (c) What MVA rating would be available for your new line? (d) Justify your choice of conductor type and bundling configuration, if any. Consider the overall costs and the performance of the new line. (e) Determine the new dispatch (Gen 1 is the most expensive unit, Gen 3 is least expensive unit) required to meet the new load. Justify your dispatch values. (f) Perform a normal case power flow study for the new 125% loading level. (g) Create a table of bus #, |V] (pu) and angle (deg). Create another table of branch flows: From, To, MW, Mvar, MVA, % loading (based on Rate A rating). (h) Perform four contingency studies for the outage of each of the four transmission lines at the new 125% loading level. (i) Create four contingency tables of bus #, |V] (pu) and angle (deg). Create four contin- gency tables of branch flows: From, To, MW, Mvar, MVA, % loading (based on Rate A rating). (i) Did you discover any overloads or low voltages (below 0.95 pu)? If any violation occured, try 1) raising the generator terminal voltage (max is 1.05 pu), or 2) adding capacitors at the load bus. Note: a 50 Mvar capacitor bank costs $750,000. (k) Compute the total cost of your substation upgrades ($2,400,000 for new 345 kV line's relays, breakers and bus work), line installation, and capacitor installation (if any).

1. Given the power system per-unit parameters and oneline diagram shown below (Note: modi- fied version of Power World Example6_14; both generators are Y-connected and solidly grounded, i.e., Zng=0), G1: 400 MVA, 15 kV, Xd'=0.24, X2=Xd"=0.12, X0=0.08, PG1~220 MW, |V1|= 1.02 G3: 800 MVA, 15 kV, Xd'=0.24, X2=Xd"=0.12, X0=0.08, PG3=520 MW, |V3|= 1.02 T1: 400 MVA, 15 kV A / 345 kV Y, X=0.08, X/R=13.33 T2: 800 MVA, 15 kV A / 345 kV Y, X=0.08, X/R=13.33 Line 2-4: R24-0.0090, X24-0.1, B24=1.72, Rate A = 1000 MVA, 200 mi Line 2-5: R25-0.0045, X25-0.05, B25-0.88, Rate A = 1000 MVA, 100 mi Line 4-5: R45-0.00225, X45-0.025, B45-0.44, Rate A = 1000 MVA, 50 mi assume a 200-Mvar capacitor has been added to bus 2, where the original load is 720 MW, 252 Mvar, and the load at bus 3 is 20 MW, 10 Mvar. The transmission network is rated 345 kV and the system base is 100 MVA. The zero sequence line reactances are three times the positive sequence reactances. The negative sequence line reactances are the same as the positive sequence values. Solve the original case power flow using Power World. Create a table of bus #, V (pu) and angle (deg). Create another table of branch flows: From, To, MW, Mvar, MVA, % loading (based on Rate A rating).

3. Suppose a three-phase fault occurs at the bus two end of one of the lines supplying bus 2, on the line side of the breaker. Eventually, the fault will be cleared by opening the breakers at both ends of the line. For now, consider the fault-on conditions. (a) Determine the fault phase currents at bus 2 for the original system without the additional 25% load. You may use the short circuit formula from lecture or Power World. (b) Determine the fault phase currents at bus 2 for the new system with the additional load and any reinforcements, such as the new line, new operating point (generator dispatch and/or terminal voltage), and new capacitors (if any). You may use the short circuit formula from lecture or PowerWorld. (c) Compare the original system fault currents to the new heavily loaded system fault cur- rents. What conclusions can you make?

4. Repeat the above analysis for a single line-to-ground fault on phase A that occurs at the bus two end of one of the lines supplying bus 2, on the line side of the breaker.

E-PORTFOLIO BRIEF Create a Mahara e-portfolio based on the template Revit and Sketching E-Portfolio. Orthographic 6 Introduction Orthographic projections are used to represent 3D components on a flat surface in a 2D form. The two main types are First Angle Projection and Third Angle Projection (TAP). We will focus on TAP. Perspective Introduction Perspective drawings represent most faithfully the way spatial configurations look in real life. They communicate overhead or suspended forms particularly well, and sections through structures that need to be seen spatially within an enclosure. Perspective grids can be con- structed simply and be drawn over again and again on tracing paper at any scale in presentation drawings or quick sketches. Isometric Introduction Isometric drawing is one of the most popular engineering drawing methods because it lets you see the top, front and side of what you are drawing. Its distortion is gentle, unlike perspec- tive, and it gives you a crisp model of what you have in your minds eye. Oblique Introduction In an elevation oblique drawing the frontal plane is an orthographic elevation and the side planes are drawn at 30° 45° or 60°. If a measured drawing is being constructed with 30° side planes, it's lengths are not fore- shortened. If 45° or 60° side planes are used, all lengths are halved to minimise the optical distortion.

Portfolio Milestone (70 Points) Important! Read First Choose one of the following two assignments to complete this week. Do not do both assignments. Identify your assignment choice in the title of your submission. Option #1: Construction Critique (Your Construction Firm) You will be working on the same project throughout the term. Your final Portfolio Project will be a compilation of your Portfolio assignments throughout the term. Assume you are the president of a construction general contractor and you intend to promote your company and attract clients. You intend to prepare a marketing and prequalification package that, at a minimum, contains the following: a. A one-page introductory letter on professionally developed letterhead that you have designed for your company. The letter properly introduces your firm, provides adequate contact information, identifies your company's areas of expertise, summarizes its past experience in performing as a general contractor, and provides other relevant and necessary information to describe why owner firms/clients should hire your firm for their construction projects. The letter is meant to function as a prequalification statement written in narrative form that describes why you believe your firm is a qualified general contractor. b. A list of at least five potential qualifying questions that you would like to receive from owner firms/prospective clients. This list is not intended to be comprehensive (all-inclusive) but it is meant to be a complete list (i.e., properly satisfying the objectives) that demonstrates the merits of your company in a reasonable and appropriate manner. By properly responding to these questions, prepare a two-page document that provides insight into your firm. Out of these five questions, a minimum of three questions should not be covered by the content of the introductory letter referenced above. Option #2 - Residential Project (Revit Architecture) Create a sample Revit model for a one-story building, consisting of a minimum of three rooms and a living area, and upload the native Revit Architecture file to the assignment area in class. At this stage, adding exterior walls, levels, grids, and columns is

ENB4002-B - CAE - Civil - Project Expectation Sheet Semester 2 - Revit (40%) Introduction Individually you are to produce a fully integrated 2D/3D models and associated documentation for the given Design and Access Statement using Revit. This piece of coursework is a vehicle for gaining understanding of the essence of understanding and awareness of the architectural drawing and relationship to spatial elements. This coursework asks you to prepare a series of annotated architectural drawings using Revit. The model can be your own house or a small building. The 3D drawings submitted must be rendered using Revit and you should try to endeavour to portray material, texture and shadowing qualities. The inclusion of the wider context occupied the architecture, such as trees, bushes, landscape features, etc. must also be carefully considered. All drawings and figures need to ‘appear' as a comprehensive set and need to be appropriately titled. Drawings in 2D/3D must be thoughtfully composed, students will be acquired to deliver a presentation in weeks 10-11. During the verbal presentation students will have the opportunity to discuss their design and show command of their Revit model. Individual PowerPoint presentation with (~20 slides) will need to be uploaded onto Canvas with appropriate 2D/3D figures of the model house/building. e.g.: Name_18001223 (obviously replace with your name and UoB number). Project Aims The aims of the Comprehensive Revit Design Project are: To understand the relationship between the model and its immediate site. To design a model that meets the general and self-imposed functional requirements and responds creatively to the identified user's needs. ● When submitting your work please upload the PowerPoint file onto canvas, name the file in the following format: Your name and uob number) ● ● To explore the appropriate use of materials. To develop design skills (spatial, formal & material integration) To integrate the knowledge achieved in the other modules. To integrate a specific typology into the design process. To apply all previously acquired design & expressive skills. To further develop presentation and graphic abilities. Project Objectives The general objectives of The Comprehensive Revit Design Project are: To develop a unique narrative for your chosen client & site To research and respond creatively to a given site, understanding it as a Real context To develop a design concept in response to the project brief and site, and to design a building to follow this proposed concept. To design an ergonomic and functional space, identifying & synthesizing user's demands To design an exciti space that responds well to the brief. To communicate effectively the design intentions / ideas through models, graphics and verbal presentations. To design a pertinent building envelope with a sound structural system. ● ● ● ● ● Every project must adhere to the following requirements: ● ● You will have to produce a 2D/3D model of a house/building. You should also consider any external covered spaces and all the necessary landscaping that will integrate your proposal to the existing conditions of the site (paths, vehicular access, parking, gardening, etc.). Each design must integrate the understanding of the dwelling. The ergonomic implications must be fully analysed and this understanding used to inform your design. Please bear in mind the FOLLOWING! Clearly illustrate both initial ideas and the design as it develops, together with the precedents that have inspired your design. How well your model is designed in response to the light throughout the day. The submission of a complete set of work which clearly and effectively communicates your project. Accurate and correctly drawn drawings of your final project. PowerPoint presentation slide layout are well thought through and easy to understand. Your verbal presentation of your work and ideas.
