🔍 Key Concepts

• Review what a synchronous compensator (synchronous condenser) does in a power system (what type of power does it mainly control?). • Consider what a frequency converter typically handles well: does it mainly transfer active power, reactive power, or both? • Look at how the synchronous compensator is connected in figure B relative to the shaft generator, frequency converter, and main bus.

💭 Think About

• Ask yourself: in an AC system, which component is usually responsible for voltage and power factor control—a synchronous compensator or a frequency converter? • Think about whether the ship’s main bus already has a source of active power from the shaft generator and auxiliaries. What ‘extra’ support might still be needed on the bus? • If the frequency converter is already passing shaft power to the mains, what limitation might it have that the synchronous compensator is meant to overcome?

✅ Before You Answer

• Verify which choices mention reactive power versus active power and match that with the known role of a synchronous condenser/compensator. • Confirm from the diagram that the compensator is not mechanically driving any load (propeller or turbine), which tells you what kind of power it mainly supplies. • Make sure the option you pick is consistent with the idea that the frequency converter’s main job is to handle frequency and active power transfer from the shaft generator, while another device handles system voltage/power factor.

As shown in figure "B" of the illustration, what is the purpose of the synchronous compensator? Illustration EL-0133

provide reactive power to the mains as the frequency converter has the ability to provide only active power

provide additional reactive power to the mains beyond the capability of the frequency converter

provide active power to the mains as the frequency converter has the ability to provide only reactive power
