Load Shedding Analysis

Load shedding is a special form of dynamic study most frequently associated with electrical systems having in-plant generation. The time period of examination is usually longer due to the slower response of governors. Loss of a major source, usually the utility, can have a severe effect on plant voltage and frequency. Rapid corrective action may be required.

A SPGS load-shedding study can help determine if standard load-shedding relays are adequate or if a computer-based load-shedding system is required. SPGS engineers examine different operating scenarios to determine the speed and amount of load to be shed for successful recovery, while keeping critical loads through a disturbance.
