Question #1 The substation below has two typical residential feeders leading out of the substation. You are adding a regulator for the longest feeder as shown and have decided to use line drop compensation. This feeder has a load of 2.5MVA 0.9 lag evenly distributed along the line. You have a regulator rated at 120V on its sensing input, and you want to set the regulator to keep the voltage at the end of the line at 1.0 pu. You want the voltage to never get more than 2% up or down. Decide on the settings you would use for the regulator and answer the following. a. Set voltage= b. Bandwith voltage= c. Time Delay= d. $R_{set}$= e. $X_{set}$= f. The regulators you have to choose from are rated at 25A, 50A, 75A, 100A, 150A 167A and 200A. Which regulator will you choose? Question #2
