Wave-shaped Mask of Fabricating Nano-scaled Structure

A wave-shaped mask for fabricating a nano-scale structure is disclosed. The wave-shaped mask comprises an elastomeric transparent substrate having an upper surface and a lower surface, and a light-penetrable thin film layer disposed on the upper surface of the elastomeric transparent substrate.
The upper surface of the elastomeric transparent substrate and the light-penetrable thin film layer are in a periodic wave shape, and the lower surface of the elastomeric transparent substrate is in a plate shape.

Earth Fault Location Based on Evaluation of Voltage Sag at Secondary Side of Medium Voltage/low Voltage Transformers

The main reasons for installation of power quality meters in distribution transformer substations are power quality monitoring and global evolution of electrical network towards the `smart grid’. In case that all measurements from the meters are properly synchronised and centralised, new possibilities of control or evaluation of the network are enabled.
This contribution proposes the possibility for an earth fault localisation with the aid of synchronised data recorded on the low-voltage side of the medium voltage/low voltage transformers in compensated neutral distribution networks which are equipped with auxiliary resistor for short-time increasing of the active part of the fault current.

Analysis of Metrological Requirements for Electrical Measurement of HVDC Station Losses

Losses of HVDC converter stations need to be accurately measured and/or estimated in order to support the evaluation of bids for such systems and to underpin efforts to reduce greenhouse gas emissions. The challenge of measurement has risen with modern converters where insulated gate bipolar transistors (IGBT) are used at high switching frequency. The theoretical bases for measurement errors are studied, both for measurement on the IGBT as a component and on complete converter stations.
The study shows that electrical measurements are difficult to augment to an accuracy level sufficient for the needs and that a supplemental method such as calorimetric measurement may be needed. In certain cases, there will be a possibility to make temporary connections to permit two converters to operate in back-to-back mode, permitting a direct measurement of losses.

Distribution Transformer For Analysing The Transformer Losses

In this project, losings due to load that is linear been calculated using analytical and simulation method and also losses because of harmonic load current is determined by analytical method. Transformer is fundamental component of energy system plus it is often constructed and basically made to just work at rated frequency and sinusoidal that is perfect current. Further losses because of current that is harmonic been determined analytically and has been in contrast to losings of linear load. A SIMULINK model of transformer is designed and finally both the method has been compared for simulation method.

Grid Synchronization of a Seven-Phase Wind Electric Generator using d-q PLL Using MATLAB

The evolving multiphase induction generators (MPIGs) with more than three phases are receiving prominence in high power generation systems. This paper aims at the development of a comprehensive model of the wind turbine driven seven-phase induction generator (7PIG) along with the necessary power electronic converters and the controller for grid interface. The dynamic model of the system is developed in MATLAB/Simulink (R2015b, The MathWorks, Inc., Natick, MA, USA). A synchronous reference frame phase-locked loop (SRFPLL) system is incorporated for grid synchronization. The modeling aspects are detailed and the system response is observed for various wind velocities. The effectiveness of the seven phase induction generator is demonstrated with the fault tolerant capability and high output power with reduced phase current when compared to the conventional 3-phase wind generation scheme. The response of the PLL is analyzed and the results are presented.

Dynamic Simulation of a Stationary Proton Exchange Membrane Fuel Cell System Using MATLAB

A dynamic model of a stationary proton exchange membrane (PEM) fuel cell system has been developed in MATLAB-SIMULINK®. The system model accounts for the fuel processing system, PEM stack with coolant, humidifier with anode tail-gas oxidizer, and an enthalpy wheel for cathode air. Four reactors are modeled for the fuel processing system: (1) an autothermal reformation (ATR) reactor, (2) a high temperature shift (HTS) reactor, (3) a low temperature shift (LTS) reactor, and (4) a preferential oxidation reactor. Chemical kinetics for ATR that describe steam reformation of methane and partial oxidation of methane were simultaneously solved to accurately predict the reaction dynamics. The chemical equilibrium of CO with H2O was assumed at HTS and LTS reactor exits to calculate CO conversion corresponding to the temperature of each reactor.
