In subject area: Engineering Synchronizer is a signal-processing block (based on phase-lock-loop techniques) to ensure compensation waveforms (IAPF and/or VAPF) are correctly synchronized with the power system voltage. From: Power Quality in Power Systems and Electrical Machines (Second Edition), ...
Assessment Block: The "flag" can be seen here again as well as 3 assessments. The latter two are used to check whether the switching of the output signal took place within the specified time frame of 5-15ms. The Data Store Memory Block itself is...
However, differently from offline assessment of STL formulas, an online monitor needs to reason on partial signals and, so, the assessment of the robustness should be adapted. We consider an established approach [12] employed by classic online monitors (ClaM in the following). It consists in ...
The preprocessing block is designed in MATLAB filter design and analysis tool. The corresponding model is realized in simulink environment. The performance measures of IIR and FIR filter are analyzed. The corresponding HDL code is generated and is targeted to a field programmable gate array board ...
[37] elaborated on a method for eliminating on-site faults of a hydraulic system based on a subjective diagnosis. In addition, Ji et al. [38] used graph theory and a block diagram to analyze the fault mechanism and diagnosis method of hydraulic components. Although a subjective diagnosis ...
An efficient algorithm to generate three-dimensional (3D) video sequences is presented in this work. The algorithm is based on a disparity map computation and an anaglyph synthesis. The disparity map was first estimated by employing the wavelet atomic fu
Assessment of Small-Signal Stability The most direct way to assess small-signal stability is via eigenvalue analysis of a model of the power system [11]–[14]. In this case, the “small-signal” disturbances are considered suf?ciently small to permit the equations representing the system to...
The classification tree representation of equivalence classes, test sequences and test steps enables the assessment of test coverage and the further elaboration on the test, i.e., the verification of the test design and the synthesis of concrete stimuli that comply to it by covering the correspond...
Hydraulic systems have the characteristics of strong fault concealment, powerful nonlinear time-varying signals, and a complex vibration transmission mechanism; hence, diagnosis of these systems is a challenge. To provide accurate diagnosis results autom
It’s worth noting that a sinusoidal signal of frequency 𝑓0f0, when used to excite a nonlinear system, results in the generation of multiple higher-order harmonics by the nonlinear block. As a result, the presence of harmonic distortion can be detected by observing the appearance of harmonic...
