Question

The main objective of Load Frequency controller is to apply control of:

• A. Frequency alone
• B. Frequency and at the same time of real power exchange via the outgoing lines
• C. Reactive power only
• D. Frequency and bus voltages

Hint:

The Load Frequency Controller (LFC) maintains system frequency and real power exchange between interconnected power systems to balance load and generation.

Answer 1

The Correct Option is B

The primary objective of the Load Frequency Controller (LFC) in a power system is to maintain the system frequency within the desired range by regulating the real power generation and ensuring power exchange between the system and external networks. This involves controlling both the frequency and the real power flow through the outgoing lines, thereby ensuring system stability. Thus, the correct answer is Frequency and at the same time of real power exchange via the outgoing lines.
