Capacity configuration ratio optimization method of power system with high permeability of wind and photovoltaic power generation

2020 IEEE Sustainable Power and Energy Conference (iSPEC), 2020
To power system with high permeability of wind and photovoltaic (PV) power generation, the capacity configuration ratio has an important influence on power consumption and power supply cost. A capacity configuration optimal planning model is proposed in this paper, which is based on the premise of same abandonment ratio of wind and PV electricity. Then,

Torque and Power Rating of a Wind-Power PM Generator Drive for Maximum Profit-to-Cost Ratio

IEEE Transactions on Industry Applications, 2013
This paper compares different solutions in micro wind-power system design. An economic analysis is carried out on the basis of the selected generator, power converter, and mechanical system. An interior permanent-magnet (PM) (IPM) generator is considered since it can be driven in the flux weakening region, exploiting higher turbine rotation speeds ...

Analysis of generalized Mach-Zehnder interferometers for variable-ratio power splitting and optimized switching

Journal of Lightwave Technology, 1999
The nonideal integrated optical N x N generalized Mach–Zehnder interferometer (GMZI) employing multimode interference (MMI) couplers is analyzed using transfer matrix techniques. Deviations in the phase relations and the power splitting ratio of the MMI couplers are included in the theory, along with the effects of phase errors in the interferometer ...

Hydrodynamic Thrust Generation and Power Consumption Investigations for Piezoelectric Fins With Different Aspect Ratios

Volume 2: Integrated System Design and Implementation; Structural Health Monitoring; Bioinspired Smart Materials and Systems; Energy Harvesting, 2015
Bio-inspired hydrodynamic thrust generation using piezoelectric transduction has recently been explored using Macro-Fiber Composite (MFC) actuators. The MFC technology strikes a balance between the actuation force and structural deformation levels for effective swimming performance, and additionally offers geometric scalability, silent operation, and ...

Torque/power rating design of an IPM machine for maximum profit-to-cost ratio in wind power generation

2011 IEEE International Electric Machines & Drives Conference (IEMDC), 2011
This paper presents some comparisons of different design choices in micro wind power systems design. An economic analysis is carried out on the basis of generator, power converter and mechanical system costs. An Interior Permanent Magnet (IPM) motor is considered since it can be driven in the flux weakening region, exploiting higher turbine rotation ...

Vibroisolation of Power Plants for New Generation Airplanes with Engines of High by-Pass Ratio

10th AIAA/CEAS Aeroacoustics Conference, 2004
On aircraft of new generation engines with high and super-high by-pass ratio are installed. Vibrational spectrum of such engines extends tending to low-frequency spectral field. It requires a new approach to vibroisolation mounting development taking into account real dynamical characteristics of modern constructions.

SIGNAL-TO-NOISE RATIO OPTIMIZATION FOR LOW-POWER LASER GENERATED ULTRASOUND

2016
The current work studies the influence of the most widely used time-domain techniques on SNR for laser-generated ultrasound, employing a low power (150 mW) modulable diode: these methods utilize highly random pseudo-noise (PN) sequences which, after the use of the cross-correlation, underline the presence of an ultrasonic output.
