The procedure used in digital processing for smoothing lines and removing distortions.
Example: The use of fiber optic connection for signal transmission reduces the overall loop delay, a key component contributing to the PHIL stability
and accuracy [32], by eliminating the D/A conversion unit and their corresponding anti-aliasing filters.
auxiliary
adjective
Providing supplementary or additional help and support.
Example: But for an accurate evaluation of the benefits of using a FESS in power systems, an accurate and validated model is necessary, which not only reflects its advantages, but also shows the practical limitations of this technology, such as its losses, its auxiliary power requirements, and its limitations during the whole operational range.
deadband
noun
The range through which an input can be varied without initiating an observable response.
Example: The P(f) characteristic, shown in Fig. 3, determines a frequency deadband of 200 mHz and different frequency droop coefficients for over- and under-frequency events.
decommissioning
verb
Withdraw (something, especially weapons or military equipment) from service.
Example: With the increasing share of converter-interfaced renewables and the decommissioning of conventional generation units, the share of
rotational inertia in power systems is steadily decreasing, leading to faster changes in the grid frequency.
hysteresis
noun
The phenomenon in which the value of a physical property lags behind changes in the effect causing it, as for instance when magnetic induction lags behind the magnetizing force.
Example: In addition, the iron losses in the PMSM, i.e., the eddy current and hysteresis losses, also increase with the angular velocity of the rotor.
latency
noun
The state of existing but not yet being developed or manifest; concealment.
Example: However, due to the nature of the Modbus protocol, a high latency and discretization is expected in the received signals from the FESS controller.
negligible
adjective
So small or unimportant as to be not worth considering; insignificant.
Example: Due to a negligible reluctance torque in a surface-mounted PMSM, the torque reference then generates the set point for the
reluctance
noun
The property of a magnetic circuit of opposing the passage of magnetic flux lines, equal to the ratio of the magnetomotive force to the magnetic flux.
Example: Due to a negligible reluctance torque in a surface-mounted PMSM, the torque reference then generates the set point for the
vice versa
adverb
With the main items in the preceding statement the other way round.
Example: Depending on the operation mode, the efficiency of a FESS can be calculated from the ratio of the power measured at the FESS terminal
to the air gap power or vice versa, as shown in (14).
windage
noun
Windage is a force created on an object by friction when there is relative movement between air and the object.
Example: Although a high-speed flywheel rotates in a vacuum enclosure, there is still a slight drag torque due to windage losses [28–30], since the vacuum in not an absolute vacuum.
