What does system integrity refer to in power management?

System integrity in power management primarily refers to the maintenance of system performance during disturbances. This concept emphasizes how resilient and robust a power system is in the face of external disruptions, such as equipment failures or sudden changes in load. When discussing system integrity, factors such as the system's ability to recover from faults, maintain stable operations, and minimize downtime are critical.

Maintaining system performance during disturbances ensures that the power supply remains steady and reliable, which is vital for both industrial and residential consumers. It demonstrates the system’s capacity to withstand or quickly recover from adverse conditions while continuing to deliver electricity effectively.

While the overall reliability of all systems relates to system integrity, it encompasses a broader scope that includes not only performance during disturbances but also the overall functioning of the power system over time. Safe operation within design limits is also essential but focuses more on operational safety rather than resilience under pressure. Meanwhile, efficiency of power transmission deals primarily with energy losses and optimization rather than the integrity of the system in challenging scenarios. Thus, the focus on performance during disturbances is what truly aligns with the concept of system integrity in power management.
