Assertion: The use of FACTS (Flexible AC Transmission Systems) devices...
Assertion: The use of FACTS (Flexible AC Transmission Systems) devices in power systems improves voltage stability.
Reason: FACTS devices can control and regulate the voltage profile in the transmission system.
Explanation:
Introduction:
- FACTS devices are power electronic devices used in power systems to enhance the control and stability of the transmission network.
- Voltage stability is an important aspect of power system operation, as it ensures that the voltage levels at various points in the system remain within acceptable limits.
Explanation of Assertion:
- The assertion states that the use of FACTS devices in power systems improves voltage stability.
- This assertion is true due to the following reasons:
1. Voltage control: FACTS devices, such as Static Var Compensators (SVC) and Static Synchronous Compensators (STATCOM), can regulate the voltage profile in the transmission system.
- These devices can inject or absorb reactive power into the system, thereby adjusting the voltage levels at specific locations.
- By maintaining voltage within acceptable limits, FACTS devices improve voltage stability.
2. Enhanced controllability: FACTS devices provide fast and precise control over the power flow and voltage in the transmission system.
- They can quickly respond to changes in load conditions and maintain voltage stability in real-time.
- This enhanced controllability allows operators to actively manage the system and prevent voltage instability issues.
3. Dynamic voltage support: FACTS devices can provide dynamic voltage support during transient conditions, such as faults or disturbances.
- They can rapidly inject or absorb reactive power to support the system voltage during such events.
- This dynamic voltage support helps in maintaining stable voltage levels and prevents voltage collapse.
Explanation of Reason:
- The reason states that FACTS devices can control and regulate the voltage profile in the transmission system.
- This reason is true and provides a correct explanation for the assertion.
- FACTS devices, through their control algorithms and power electronic converters, can actively adjust the voltage levels and maintain stability in the transmission network.
Conclusion:
- Both the assertion and the reason are true, and the reason provides a correct explanation for the assertion.
- The use of FACTS devices in power systems improves voltage stability by controlling and regulating the voltage profile in the transmission system.
Reason: FACTS devices can control and regulate the voltage profile in the transmission system.

Assertion: The use of FACTS (Flexible AC Transmission Systems) devices...
FACTS devices are advanced power system devices used to control and optimize the operation of AC transmission systems. One of the significant advantages of FACTS devices is their ability to improve voltage stability in power systems.
FACTS devices such as Static VAR Compensators (SVCs) and Thyristor-Controlled Series Capacitors (TCSCs) can regulate and control the reactive power flow in the system, which helps in maintaining the voltage profile within desired limits. By injecting or absorbing reactive power as required, FACTS devices can dynamically control the voltage levels and enhance voltage stability.
Therefore, both the Assertion and Reason are true, and the Reason provides a correct explanation of the Assertion.
