Abstract:
1. A system for monitoring electromechanical damping compliance of power generated by a power generation unit for supply to a power delivery network, the system comprising: a measurement unit adapted to be coupled to the delivery network, said measurement unit configured to identify the voltage and current values output by the power generation unit; a database adapted to maintain at least one prior electromechanical damping value associated with the operation of the power generation unit; and a processing system coupled to said measurement unit and said database, said processing system maintaining a plurality of parallel model-based filters coupled to an estimation unit, said model-based filters configured to define the operation of the power generation unit based on at least the identified voltage and current values, so as to generate at least one output value processed by said estimation unit to estimate an electromechanical damping value, wherein said processing system compares said estimated electromechanical damping value with said at least one prior electromechanical damping value to determine if said estimated electromechanical damping value varies from said at least one prior electromechanical damping value.
