What is the required update duration for changes in 500/345/230 kV tap positions?

• A. 15 minutes
• B. 30 minutes
• C. 45 minutes
• D. 1 hour

Answer: (B)

The required update duration for changes in 500/345/230 kV tap positions is set at 30 minutes because it strikes a balance between the operational needs of managing the transmission network and ensuring system reliability. Higher voltage systems, such as those at 500 kV and 345 kV, often have strict operational standards due to their significant impact on the overall power grid. The 30-minute duration allows for sufficient time to gather necessary data, make adjustments, and facilitate communication among grid operators. This timeframe helps ensure that any potential changes do not disrupt the stability of the grid or lead to unintended consequences in power flow or system reliability. Therefore, setting a 30-minute duration effectively aligns with the operational protocols necessitated by high-voltage transmission networks.
