Question: PW 2.32. In PowerWorld Simulator Problem 2.32 (see Figure 2.28) a 8 MW/4 Mvar load is supplied at 13.8 kV through a feeder with an impedance of 1+2 2. The load is compensated with a capacitor whose output, Qap, can be varied in 0.5 Mvar steps between 0 and 10.0 Mvars. What value of Ocup minimizes the real power line losses? What value of Qcap minimizes the
Question: PW 5.43 Open PowerWorld Simulator case Example 5_4 and graph the load bus voltage as a function of load real power (assuming unity power factor at the load). What is the maximum amount of real power that can be transferred to the load at unity power factor if we require the load voltage always be greater than 0.9 per unit?
What is the maximum amount of real power that can be transferred to the Mud at unity power factor if we require the load voltage always be greater than 0.85 per unit? 5.66 Open Power World Simulator case Example 5_10 with the series capacitive compensa- tion at both ends of the line in service.
Question: Load PowerWorld Simulator case Problem 6_46. Plot the reactive power output of the generator at bus 2 as a function of its voltage setpoint value in 0.005 pu voltage steps over the range between its lower limit of -50 Mvar and its upper limit of 50 Mvar. To change the generator 2 voltage set point first select Tools, Play to begin the power flow simulation,
Traditional power flow programs usually indicate power flow direction using a con- vention that flow into a transmission line or transformer is assumed to be positive. You can display results in Power World Simulator using this con- vention by first clicking on the Onelines ribbon and then selecting Oneline Display Options.
