Question

Shunt Compensation Problem Consider a transmission line having V 220V, f = 56kW. We want to 60HZ, X 1.20hm, and P_p shunt compensate this transmission line. Calculate: 1. Phase angle ? (delta) 2. Line current I 3. Reactive power Q_p of the shunt capacitive? compensator. Is this inductive or 4. Current I_comp flowing through the shunt compensator 5. Shunt capacitance needed. To perform the shunt compensation, you have available to you TSCS having a fixed capacitive impediance X_TSC 3.67ohm and a TCR having inductive reactance XL = 2.2ohm an 6. How many TSCS do you need to obtain a shunt compensation as close as possible to the desired value? 7. You can use the controllable TCR to adjust the shunt compensation to the correct value. How many TSCS do you use? What is the angle (alpha) for the TCR?
