Abstract: The invention is related to a method, power control device and computer program product for tuning a power oscillation damping unit (22; 26) in a power transmission system,. The power control device (10) includes a probing signal generating element (42) configured to generate at least one probing signal (PS) and send the probing signal into the power transmission system,a data extracting element (36) configured to receive probing signal responses (PSR1, PSR2, PSRn) from measurement units (12, 14, 16) placed in the power transmission system and a system parameter determining element (40) configured to determine system model parameters (SP1; SP2) of the power transmission system based on the probing signal and the probing signal responses and tune the power oscillation damping unit using the system model parameters.

Abstract: The invention provides improved control of a power transmission system having a first group of measurement units (10, 12, 14) in a first geographical area (A_1) providing a first set of phasors and a second group of measurement units (16, 18) in a second geographical area (A_2) providing a second set of phasors, where the phasors in the sets are generated at the same instant in time. In this system the power control device (32) includes a phasor aligning unit (30) that time aligns the first and second sets of phasors and a control unit (33) that compares each set of phasors with a corresponding phasor number threshold, determines that a first control condition is fulfilled if each phasor number threshold has been exceeded and enables the provision of a common signal if the first control condition is fulfilled. The common signal is based on the obtained phasors in the first and second sets.

Abstract: La invención proporciona un control mejorado de un sistema de transmisión de energía que tiene un primer grupo de unidades de medición (10, 12, 14) en una primera área geográfica (A-1) que proporciona un primer conjunto de fasores y un segundo grupo de unidades de medición (16, 18) en una segunda área geográfica (A_2) que Proporciona un segundo conjunto de fasores, donde los fasores en los conjuntos se generan en el mismo instante de tiempo. En este sistema, el dispositivo de control de energía (32) incluye una unidad de alineación de fasores (30) que almea en el tiempo a los conjuntos de fasores primero y segundo y una unidad de control (3) que compara cada conjunto de fasores con un umbral de número de fasor correspondiente, determina que se satisface una primera condición de control si cada umbral de número de fasor se ha excedido y permite el suministro de una señal común si se satisface la primera condición- de control. La señal común se basa: en los fasores obtenidos en los conjuntos primero y segundo.
