How does a static VAR compensator function when in automatic mode?

A static VAR compensator (SVC) operates by dynamically adjusting reactive power to stabilize the voltage in a power system, particularly during load variations. When in automatic mode, it continuously monitors the grid conditions and responds in real-time to changes in the load. This capability allows it to either supply or absorb reactive power as needed, ensuring voltage levels remain within desired limits and improving the overall stability of the power system.

The primary objective of the SVC is to enhance reactive power management. As load demands increase or decrease, the SVC compensates for these fluctuations, maintaining optimal voltage levels and minimizing the risk of voltage instability, which can lead to outages or reduced system performance. In essence, the automated response of the SVC is crucial for maintaining system reliability, especially in variable load conditions.

Other options, while related to power systems, do not accurately describe the essential operation of a static VAR compensator in automatic mode. For example, synchronizing with generators is a function of synchronous machines rather than the SVC, and while limiting transmission losses is a goal of power system management, it is not a direct operation of the SVC. Similarly, automatically disconnecting from the grid is not a typical function of an SVC; instead, it strives to remain
