Monitoring the insulation condition of power cables is essential for ensuring safe and stable operation substation supply system. Leakage current an important indicator performance cables. However, application leakage monitoring methods in substations limited due to issues such as neutral line shunting on load side spatial isolation phase-to-neutral cabinet. This paper proposes method based distributed principal component analysis substations. Firstly, cable measured by a extraction method,...
The status of zinc oxide (ZnO) arresters is directly related to the safety power grids. However, as service life ZnO increases, their insulation performance may decrease due factors such operating voltage and humidity, which can be identified through measurement leakage current. Tunnel magnetoresistance (TMR) sensors with high sensitivity, good temperature stability, small size are excellent for measuring This paper constructs a simulation model arrester investigates deployment TMR current...
State-of-charge estimation and on-line model modification of lithium-ion batteries are more urgently required because the great impact accuracy on algorithm performance. This study aims to propose an improved DUKF based state-parameter separation. Its characteristics include: (1) State-Of-Charge (SoC) is treated as only state variable eliminate strong correlation between parameters. (2) Two filters ranked run parameter when has converged. First, double polarization (DP) battery established,...
Tunnel magnetoresistance (TMR) can measure weak magnetic fields and has significant advantages for use in alternating current/direct current (AC/DC) leakage sensors power equipment; however, TMR are easily perturbed by external fields, their measurement accuracy stability limited complex engineering application environments. To enhance the sensor performance, this paper proposes a new multi-stage AC/DC structure with high sensitivity anti-magnetic interference capability. The front-end...
An artery stiffness measuring system was developed based on LabVIEW for the multiparameter measurement of cardiovascular hemodynamics. The overall hardware and software design were introduced. basic theory methods described calculation pulse wave velocity (PWV), index (ASI), aorta compliance (C1) arteriole (C2). In order to illustrate effectiveness system, comparative clinical trial performed 218 participators by carotid intima-media thickness (CIMT) using ultrasonography instrument...
With the portable electronics becoming more and popular, a model of wireless power transmission for general was presented based on principles magnetic resonance transmission. And that transferring to an equivalent circuit possible calculate. The characteristics system optimal conditions were analyzed, influence efficiency Coupling factor Quality discussed. theory analysis simulation in MATLAB show performance can be optimized by adjusting coupling between transmitter coils. Furthermore,...
In this paper an advanced algorithm based on G-P is introduced to calculate the correlative dimension (CD) of HRV signals. Moreover, Theiler's correction considered avoid autocorrelation effect time serials. It will reduce possibility get spurious dimension. The applied clinical data which are collected from twelve young healthy subjects under two conditions: 1) normal state; 2) autonomic nervous system (ANS) being blocked by certain acute selective blocking drug: Atropine or Metoprolol....
Pulse wave velocity (PWV) and arterial stiffness index (ASI) are considered as the independent predictors of cardiovascular morbidity mortality — effective methods to assess stiffness. A portable noninvasive elasticity detecting system (PNAEDS) was developed based on embedded microprocessor unit. This can simultaneously measure PWV, ASI other arteriosclerosis critical risk factors. Algorithm main factors design were described in detail. To verify performance PNAEDS, laboratory prospective...
For the purpose of measurement and evaluation arterial stiffness, we design a noninvasive medical device based on oscillometric method pulse wave velocity (PWV) method, employ stiffness index (ASI) PWV as accessing parameters. The inner pressure signal cuff upper arm at tip finger will be sampled, special software can utilize these signals to calculate two parameters obtain conclusion stiffness. clinical experiments show that this are effective valuable.
Wireless power transfer systems are widely used, but the decrease of efficiency caused by offset needs to be dealt with urgently. Changing coil structure affect magnetic field and mutual inductance adopted researched. ANSYS Maxwell is used build a typical coupling model observe influence through coefficient distribution field. The optimized design new quadrilateral overlapped wireless transmission achieves large-scale even in center. Through simulation experiment, it verified that change...
Abstract State-of-charge (SOC) estimation is essential in the energy management of electric vehicles.
