ABSTRACT:
A system and method for monitoring the power damping compliance of a power generation unit comprises a measurement unit that is configured to be coupled to a power generation unit to identify the voltage, current, and frequency values associated with power output therefrom. A processing system maintaining a model-based filter processes the voltage, current, and, frequency values to estimate the total amount of damping provided by the power generation unit. The estimated total damping is compared to prior historical values maintained in a database using various statistical techniques to determine if a power system stabilizer (PSS) provided by the power generation unit is being operated in a manner complying with predetermined guidelines.
