摘要： A telescopic fork leg incorporates mutually displaceable inner and outer tube parts and a damping arrangement for damping the relative movements of the tube parts. The damping arrangement comprises tubular and coaxially disposed units. A piston belonging to the first outer tube part operates in a chamber within the interior of the tubular units in a medium present in the chamber, which medium, at a piston speed above a chosen value, is transferred between the top and bottom sides of the piston via passage(s) disposed in, on or by the piston and damping-influencing members, for example in the form of shims. The passage(s) is/are closed by the damping-influencing member(s) at piston speeds below the said values and the medium is conducted only via one or more leak flow paths extending from the chamber on one side of the piston, via a gap between the outside of the inner tubular unit and within a second tubular unit disposed outside the inner unit, one or more leak-flow-size-determining members, and back to the chamber on the other side of the piston. The said member(s) is/are arranged so as to be adjustable. In the case of existing or establishable leak flows in both the compression and the return directions, the leak flow in one direction does not affect the leak flow in the other direction. Adjustable leak flows can be easily arranged around the piston and an important component in the leg can operate with dual function by being assigned both a strength function and a leak-flow-conducting function.

摘要： A method and system are provided for determining a length quantity of a power transmission line, which connects a first location with a second location. A first signal having a first carrier frequency is provided at the first location. The first signal is transmitted from the first location to the second location via the power transmission line. A second signal having a second frequency is provided at the second location. A first phase difference between the first signal and the second signal is measured at the second location, and the length quantity is calculated from the measured phase difference. In the system, a second receiver at the second location is configured to receive the first signal having the first carrier frequency from the first location. A frequency generator creates the second signal having the second frequency at the second location. The receiver includes a phase detection device configured to detect a first phase difference between the second frequency and the first carrier frequency at the second location.

摘要： Methods for detecting network model data errors are disclosed. In some examples, methods for detecting network model data errors may include splitting a network model into a first plurality of portions, executing an algorithm on each of the portions, identifying a portion for which the algorithm is determined to be non-converged, splitting the identified portion into a second plurality of portions, repeating the executing, identifying and splitting the identified portion until a resulting identified portion is smaller than a predefined threshold, and examining the resulting identified portion to identify plausible data errors therein. In some examples, examining the resulting identified portion to identify plausible data errors therein may include executing a modified algorithm, which may include an augmented measurement set, on the identified portion.

摘要： The present disclosure is concerned with the combined voltage or power flow control and damping of electromechanical oscillations in an electric power system by Flexible AC Transmission System (FACTS) devices or High Voltage DC (HVDC) transmission devices. To this end, information about a state or operating point of the power system is generated from suitable second system signals (y2) and a control parameter (cp) of a FACTS controller is derived therefrom. The control parameter and a first system signal (y1) are used in the calculation of a control command (u) defining the settings of the FACTS device. Following a change in the state of the power system such as a change in the topology of a transmission network, poorly damped or even unstable oscillations are avoided by appropriate re-tuning of the control parameter of the damping or stabilizing equipment.

摘要： The present disclosure relates to power system sensitivities as computed 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, 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 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： A sample preparation method for characterization of nanoparticles embedded in the supports of heterogeneous catalysts, with improved particle dispersion, is introduced. The supported catalyst is first ground or milled into fine powder. Then, the powder is mixed into an organic solvent, and an etchant is added to the solvent to digest the supports and release metallic nanoparticles. The resulting solution is then placed in an ultrasonic bath where ultrasonic waves are generated and applied to the solution. The ultrasonic waves suppress agglomeration of the particles and also break up those particle clusters resulting from agglomeration during the prior steps. Subsequently, a sample is extracted from the solution and prepared for analysis.

摘要： In a method, computer program and system for determining an operational limit of a power transmission line, time-stamped current phasor information and voltage phasor information for a first end and a second end of the line are determined, an ohmic resistance of the line is computed from the phasor information, and an average line temperature is computed from the ohmic resistance. This allows to determine the average line temperature without dedicated temperature sensors. The average line temperature represents the actual average temperature and is largely independent of assumptions regarding line parameters.
