An isolated 50 Hz synchronous generator is rated at 15 MW which is also the maximum continuous power limit of its prime mover. It is equipped with a speed governor with 5% droop. Initially, the generator is feeding three loads of 4 MW each at 50 Hz. One of these loads is programmed to trip permanently if the frequency falls below 48 Hz. If an additional load of 3.5 MW is connected then the frequency will settle down to
| List I To | List II Use |
|---|---|
| a. improve power factor | 1. shunt reactor |
| b. reduce the current ripples | 2. shunt capacitor |
| c. increase the power flow in line | 3. series capacitor |
| d. reduce the Ferranti effect | 4. series reactor |
Which of the following options is/are correct for the Automatic Generation Control (AGC) and Automatic Voltage Regulator (AVR) installed with synchronous generators?
