- PV station 8.6 Consider the microgrid given in Figure 8.56. The positive sequence impedance of the transmission lines is given in the one-line diagram (Figure 8.56). The system data are as follows: PV generating station: 2 MW, 460 V AC; positive, negative, and zero sequence impedance of each line is equal to 10%. The gas turbine gen- erating station is rated at 10 MVA, 3.2 kV, with positive sequence reac- tance of 10%. The generator negative sequence impedance is equal to the positive sequence, and the zero sequence impedance is equal to half (1/2) of the positive sequence impedance. Transformers' positive sequence impedance is equal to the negative sequence and equal to the zero sequence impedance.

- Don't use ai to answer I will report you answerarrow_forwardYou are tasked with designing an electronic system for sensing the magnitude of a measurand (details and values to be provided on the day of the exam). The system must alert a user to a measurand value above a threshold, measured by an appropriate sensor, by turning on a buzzer (to make a sound). The buzzer must remain off below this threshold. All resistors used must be from the E12 series. This work is to be performed on TinkerCAD. To fully answer the question, you must provide: • Full calculations for all components you use, clearly indicated what you are calculating. • A screenshot of the TinkerCAD circuit with it in the buzzer off state (clearly showing the full circuit including the sensor). • A screenshot of the TinkerCAD circuit with it in the buzzer on state (clearly showing the full circuit including the sensor). • A written explanation of how the circuit works and justification of your design (approx. 200 words).arrow_forwardcan I have a written solutionarrow_forward
