Condition monitoring of stator windings in induction motors. II. Experimental investigation of voltage mismatch detectorsIEEE Transactions on Industry Applications - Tập 38 Số 5 - Trang 1454-1459 - 2002
J. Sottile, F.C. Trutt, J.L. Kohler
For pt.I see ibid., vol.38, no.5, p.1447-53 (2002). Condition-based maintenance
(CBM) of industrial equipment is generally recognized as being the most
cost-effective means for improving equipment availability. However, a
prerequisite to successful implementation of CBM is a reliable detector of
failing components. One such detector, termed the effective negative-sequence
impedance, had previously... hiện toàn bộ

Globoidal cam indexing servo drive control by IVSMFC with load torque estimatorIEEE Transactions on Industry Applications - Tập 38 Số 5 - Trang 1326-1333 - 2002
Geeng-Kwei Chang, Tzuen-Lih Chern, Der-Min Tsay
This paper introduces an integral variable-structure model-following control
(IVSMFC) incorporated with a load torque estimator based on variable-structure
technique for a globoidal cam indexing system. IVSMFC features excellent
robustness and performance properties under certain disturbances and parameter
variations. However, heavy time-varying load may influence expected performance.

Price Incentive-Based Charging Navigation Strategy for Electric VehiclesIEEE Transactions on Industry Applications - Tập 56 Số 5 - Trang 5762-5774 - 2020
Xuecheng Li, Yue Xiang, Lin Lyu, Chenlin Ji, Qian Zhang, Fei Teng, Youbo Liu
With rapid development of the electric vehicle (EV) industry, charging
infrastructures are built fast. However, the unreasonable deployments with
increasing EVs contribute to a long queuing time for charging demand of EVs,
especially in the peak hours. How to navigate a specific EV to economically
satisfy its charging demand, while relieve the traffic burden, is an urgent
problem. To address that,... hiện toàn bộ

Condition monitoring of stator windings in induction motors. I. Experimental investigation of the effective negative-sequence impedance detectorIEEE Transactions on Industry Applications - Tập 38 Số 5 - Trang 1447-1453 - 2002
J.L. Kohler, J. Sottile, F.C. Trutt
The former US Bureau of Mines funded a research project aimed at developing the
enabling technology for incipient failure prediction in electric power system
components as a means of reducing the injuries and fatalities that sometimes
occur when equipment malfunctions. Over the ensuing years, interest in this has
waxed and waned, but interest has been growing for both civilian and military
applica... hiện toàn bộ

Design considerations for a soft-switched modular 2.4-MVA medium-voltage driveIEEE Transactions on Industry Applications - Tập 38 Số 5 - Trang 1400-1411 - 2002
A. Bendre, I. Wallace, G.A. Luckjiff, S. Norris, R.W. Gascoigne, D. Divan, R.A. Cuzner
A new six-phase 2.4-MVA soft-switched medium-voltage drive system utilizing
series-stacked modules with low-voltage devices has been developed. The drive
system combines a new soft-switched DC-DC converter with resonant DC-link
inverter technology to deliver extremely low total harmoic distortion sinusoidal
output, high power density, and high efficiency. The series-stacked
configuration with the ... hiện toàn bộ

Fuzzy-logic-based power control system for multifield electrostatic precipitatorsIEEE Transactions on Industry Applications - Tập 38 Số 5 - Trang 1190-1195 - 2002
N. Grass
The power consumption of large precipitators can be in the range of 1 MW and
above. Depending on the dust load properties, the electrical power may be
reduced by up to 50% by applying fuzzy logic, without significantly increasing
the dust emissions. The new approach uses fuzzy logic for optimization of
existing electrostatic precipitators. The software runs on a standard personal
computer platform... hiện toàn bộ

Conducted EMI in PWM inverter for household electric applianceIEEE Transactions on Industry Applications - Tập 38 Số 5 - Trang 1370-1379 - 2002
Yo-Chan Son, Seung-Ki Sul
This paper presents the mitigation effort of the conducted electromagnetic
interference (EMI) in the pulsewidth-modulation (PWM) inverter for household
electric appliances. First, noise sources in the PWM inverter are investigated
to get an understanding of their characteristics, and the propagation of the
conducted EMI is described. Next, input filters are added to: suppress it. With
changing fil... hiện toàn bộ

The IEEE 522 guide for testing turn-to-turn insulation in form wound coils for
alternating-current machines is currently under working group review, with the
intent to eliminate problems in interpretation and application. The guide is
written for the testing of fully processed coils, while the motor industry uses
the test guide for pre-impregnated vacuum-pressure-impregnated coils wound in
the sta... hiện toàn bộ
