A 1000 MVA rated generator that produces 800 MW and 100 MVAR is best described as?

• A. Operating in a leading mode. Capacitive system
• B. Operating in a lagging mode. Inductive system
• C. Operating at unity power factor
• D. Underloaded

Answer: (B)

The generator producing 800 MW of real power and 100 MVAR of reactive power can be analyzed to determine its operating mode. The key to understanding the operation lies in the relationship between the real and reactive power. When the power factor is calculated, the real power (MW) and reactive power (MVAR) can be used to assess whether the generator is consuming or supplying reactive power. In this case, the generator is producing positive real power (800 MW) and positive reactive power (100 MVAR). The presence of both types of power indicates that the generator is producing power but also supplying reactive power to the system. Since the generator is providing reactive power, it indicates a lagging power factor, which generally corresponds to inductive behavior within the system. Inductive loads (like motors and transformers) draw reactive power and create a lagging power factor, which is the case here. Thus, the generator is operating in a lagging mode, contributing to the overall inductive nature of the power system it is part of. In summary, the generator's output characteristics of both real and reactive power illustrate that it is indeed operating in a lagging mode, characterized by its contribution to the inductive properties of the electrical system, reinforcing the correctness of
