Measurements of Harmonic Voltages at Multiple Locations in LV and MV Networks

, 2020
This paper presents harmonic voltage measurements for a part of a distribution network including low-voltage (400 V) and medium-voltage (10 kV). Measurements were performed during 2017 and 2018 in the north of Sweden.

Synthesis of Ti2B2Clx MBenes in Molten Salts From Theoretical and Experimental Perspectives

Advanced Materials, EarlyView.
By integrating a theoretical framework with experiments, Ti2InB2 was selectively etched with ZnCl2 to produce a multilayer (ml) Ti2B2Clx MBene. The In atoms are completely removed, with simultaneous incorporation of chlorine surface terminations. in situ x‐ray diffraction indicates a direct biphasic transformation from Ti2InB2 to ml‐MBene, with no ...

Vibration analysis of a nine-phase induction machine supplied by voltage with harmonics injection

, 2020
The paper deals with magnetic forces and vibration analysis of a nine-phase induction motor. It is described a method of voltage harmonics injection for reaching either the same amplitude or RMS value of supplying voltage as for the case of supplying the

Blending With Insulating Polymers Enables Stable Anti‐Ambipolar Characteristics in n‐Type Organic Mixed‐Conductors for Heterogeneous Spiking Neurons

Advanced Materials, EarlyView.
A polymer blend of n‐type OMIEC P(gNDI‐gT2) with insulating PMMA yields mechanically stabilized, anti‐ambipolar organic electrochemical transistors (OECTs) with tunable ionic‐electronic transport. This blending allows low‐power, fast‐spiking heterogeneous Hodgkin–Huxley neurons, enabling biomimetic frequency deconvolution and reservoir computing, which

Application of Quasi Proportional Resonance Control Algorithm in Three-phase Inverter Power

机车电传动, 2020
Nonlinear loads introduce harmonics into the three-phase inverter power system, which damages the electrical equipment. In order to reduce the harmonic content of the inverter output voltage, a harmonic suppression method based on the quasi-proportional ...

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

Advanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Harmonic voltage phasor reconstruction and harmonic state estimation based on the measurement data of a capacitive voltage transformer

IET Electric Power Applications
Abstract Harmonic state estimation, which highly depends on accurate synchronised phasors, is a crucial basis for the location, traceability, and governance of harmonics in power systems. However, most existing synchronous phasor measurement units (PMUs) provide power frequency phasors rather than harmonic phasors. In addition, as the
