摘要： The present invention is concerned with the monitoring of electromechanical oscillations in electric power systems, and their identification by an adaptive algorithm based on a repeatedly measured and evaluated signal as detailed in EP-A 1 489 714. In order for an estimation of parameters of a model of the power system to reasonably converge, proper initialisation of the recursive calculation is required, including the definition of tuning parameters constraining the model and the calculation. Initialisation for a second signal to be exploited can then be simplified by copying the set of tuning parameters tuned previously for a different signal. A conditioning gain multiplying the second signal establishes compatibility between the different signals, and a signal pre-filter in turn discards contributions beyond a frequency band comprising typical electromagnetic oscillations.

摘要： 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.

摘要： The present invention is concerned with the computation of power system sensitivities from power flow parameters and control parameters of a Power Flow Control Device (PFC). To this end, control parameter variations are applied to or generated by a PFC (20), and comprise variations in a control input u, a control effort e (injected series voltage, inserted series reactance), or a control effect q (power flow, active power transfer, phase-shift, current). A power flow response measuring unit (40) measures a variation of a power flow response such as current, active or apparent power, in a way sufficiently synchronized with the control parameter variation to allow establishing an unambiguous causal relationship or correspondence in the form of a power system sensitivity. The latter may be on-line adapted to continuously reflect an updated aspect of the power system behaviour, and thus enable an improved, fast and reliable power flow control in power systems comprising a meshed power network with two parallel flow paths or corridors connecting two areas or sub-systems.

摘要： The present invention is concerned with a faster response and an increased accuracy in power system protection. According to the invention, a fault, instability or other contingency potentially requiring some protective action, such as line tripping or load adaptation, is detected in a fast and precise way by tracking a non-frequency-selective evolution of a physical parameter (R, L) in time domain, preferably with adaptive filters. By reverting to a physical parameter having an imminent physical significance, no additional analysis is required to divulge a fault or contingency, hence the speed of fault detection increases. Due to the skin affect in electrical conductors, a time domain analysis covering a broad range of frequencies includes more information than an analysis confined to the fundamental or line frequency, hence the accuracy of the fault detection increases.

The system of controlling comprises at least one phasor measurement unit (58, 60, 62, 64) obtaining phasor data signals including oscillating mode signals, at least one wide area control system (66) receiving the phasor data signals from the phasor measurement unit, and at least one actuating device (80, 82, 84) for receiving a control signal from the wide area control system. Specifically, the wide area control system performs the fault tolerant control method of the present invention, wherein information about each critical oscillatory mode of an oscillation is extracted from a model, selected residues for each critical oscillatory mode are grouped together, and a partial damping controller is designed for each selected critical oscillatory mode using residues from the same group. A multivariate damping controller is produced and applied to one or more actuating devices in the power system to control electromechanical oscillations.

摘要： A relationship between a temperature T 1 of a power line or power transmission conductor 10, an electrical quantity of the power line such as a current I or power flow P through the power line, as well as meteorological quantities or ambient conditions of the power line such as wind speed W , wind direction, humidity, solar radiation S and ambient temperature T a, is established in the form of a thermal model of the power line. Values of the aforementioned quantities or variables are continuously measured, and the collected values of the quantities are evaluated in order to update model parameters of the thermal model during operation of the power line. In a preferred embodiment of the invention, an average temperature representative of the entire line is determined via two Phasor Measurement Units (PMU) 11, 11 ' providing synchronized phasor values from two ends of the power line. An ohmic resistance of the power line is computed from the phasor values, from which in turn the average line temperature can be derived.
