EEP303: Cycle ii exp 2
The document describes an experiment to study the steady state power limit of a transmission line. It defines the equations for real and reactive power transfer between the sending and receiving ends of a lossless transmission line based on voltage and reactance. A power-angle diagram is drawn by plotting real power transferred versus the phase angle between voltages, showing that maximum power transfer occurs at a phase angle of 90 degrees. The results of the experiment show the steady state power limit is reached at 22W when the phase angle is 81.526 degrees, and that real power transfer varies linearly with changes in the sending end voltage.
3 phase motors 1
The document discusses 3-phase motors and how they produce a rotating magnetic field using 3 stator windings that are 120 degrees apart, powered by a 3-phase supply with voltages that are also 120 degrees apart. This rotating magnetic field is produced as the magnetic flux from each winding rotates continuously, causing the field to move around the stator. The speed of this rotating field is determined by the supply frequency and number of poles in the stator windings. As the rotor lags behind this rotating field, it produces torque.

Chapter 13
Mutual inductance relates the voltage induced in one circuit to a time-varying current in another circuit. The coefficient of coupling measures the degree of magnetic coupling between 0 and 1. Reflected impedance is the impedance of one circuit seen from the other circuit in a transformer. An ideal transformer is a lossless device with infinite inductance and unity coupling that can match load and source impedances to maximize power transfer.

Electromechanical energy conversion principles
This document contains a summary of the key concepts from the chapter "ELECTROMECHANICAL CONVERSION PRINCIPLES" in the textbook "ELECTRICAL MACHINES". It explains that electromechanical systems convert energy between electrical and mechanical forms by using magnetic and electric fields to store energy. Electromechanical devices can produce small motions, forces, or continuous energy conversion as in motors and generators. The magnetic field has much greater energy storage capacity than the electric field. The principle of energy conversion states that energy cannot be created or destroyed, only converted between different forms.

The equivalent circuit model for a DC motor simplifies the circuit by eliminating the brush voltage drop and combining the armature resistance with the field resistance.

Elextrostatic and Electromagnetic Fields Actuators for MEMS AD/DA Converters
MEMS Analog -to-digital and digital-to- analog converters are proposed using electrostatic field and electromagnetic fields actuators. For the former, parallel deformable plates supported by springs are used with bias applied voltage which determines the amount of static displacement needed for equilibrium condition. For the latter, coil winding(s) are embedded in a rotating plate, which is exposed to a constant field of a permanent magnet, causing the plate to deflect according to the currents in the windings. In the analog-to-digital arrangement, different spring displacements are tapped off either the spring in case of electrostatic or the moving plate in case of electromagnetic actuators, corresponding to the binary decoded currents. At these off tapping points, logic high signal levels are applied at these locations so that when a certain analog voltage is applied on the moving plate of the capacitor, the spring is displaced to one of these locations, enabling different binary voltages to all switches up to that level. Similar result occurs when an analog voltage is applied on the winding. The digital binary voltages are fed to a priority encoder to obtain the digital value. In digital-to-analog arrangement, the input binary voltage is decoded to different spring locations which correspond to resistances making up a potentiometer circuit for the output analog voltage. Similarly; for the electromagnetic actuator, a number of different length coil windings are embedded within the moving plate, causing different deflections corresponding to one bit of the binary input.
Variable Voltage Source Equivalent Model of Modular Multilevel Converter
The structures of modular multilevel converter module (MMC) are very complex, and the
numerous sub-modules and output level number bring difficulties for the analysis and simulation. In this paper,
assuming the sub-capacitor voltage instantaneous value of a single arm is the same value, the switching
frequency of the switch is much higher than the output voltage frequency, the system harmonics were ignored,
the system state equations are deduced about the intermediate variables as circulation current and the capacitor
voltage between the upper and lower arms. On this basis, a variable voltage source continuous equivalent
model is proposed, which may replace the system physical simulation model with the actual simulation study. At
the same time, the model reflects the relationship between the output voltage and circulation current，which
provide a way to analyze the formation mechanism of circulation and the capacitor voltage fluctuations, and
make system analysis simple and intuitive. The simulation results validate that this continuous model is
rationality and correctness.

This document summarizes a research paper that proposes using artificial neural networks to generate optimal switching functions for voltage and harmonic control of three-phase inverters. Specifically:
1) A new training algorithm is developed for an artificial neural network to determine switching angles without using pre-computed desired angles. Instead, it uses the desired solution of harmonic elimination equations.
2) Theoretical analysis of the proposed solving algorithm with neural networks is provided. Simulation results show the high performance and advantages of the developed modulator.
3) An artificial neural network is trained using a backpropagation algorithm. Training data comes from optimal switching angles determined through selective harmonic elimination equations for different modulation indices.

This document discusses using artificial neural networks to solve the harmonics elimination problem in three-phase voltage-controlled inverters. It presents a new training algorithm for an ANN that does not use pre-computed switching angles from classical harmonic elimination methods. Instead, it trains the ANN by using the desired solution of the harmonic elimination equations, with the first harmonic equal to the modulation index and higher harmonics equal to zero. Theoretical analysis and simulation results show the high performance of using this ANN approach for generating optimal switching functions to control harmonics in inverters.
Labo circuito en rc
This document describes an experiment on RC circuits. The objectives are to obtain the charging and discharging curves of a capacitor using a simulator and to determine the capacitance C of the electrolytic capacitor. The theoretical framework describes the RC circuit and the equations that characterize the voltage over time for the resistor and capacitor. The procedure involves using a simulator to set up an RC circuit and record voltage values over time for charging and discharging. The results are tables of voltage vs. time data and graphs of the theoretical and experimental curves. It is determined that the maximum experimental voltage does not reach the theoretical voltage due to small errors in measurement.
ANALYSIS OF LIGHTNING STRIKE WITH CORONA ON OHTL NEAR THE SUBSTATION BY EMTP

Solar Module Modeling, Simulation And Validation Under Matlab / Simulink
Solar modules are systems which convert sunlight into electricity using the physics of semiconductors. Mathematical modeling of these systems uses weather data such as irradiance and temperature as inputs. It provides the current, voltage or power as outputs, which allows plot the characteristic giving the intensity I as a function of voltage V for photovoltaic cells. In this work, we have developed a model for a diode of a Photovoltaic module under the Matlab / Simulink environment. From this model, we have plotted the characteristic curves I-V and P-V of solar cell for different values of temperature and sunlight. The validation has been done by comparing the experimental curve with power from a solar panel HORONYA 20W type with that obtained by the model.

二、回国进私企、外企、自己做生意的情况，这些单位是不查询毕业证真伪的，而且国内没有渠道去查询国外文凭的真假，也不需要提供真实教育部认证。鉴于此，办理一份毕业证【微信176555708】即可
三、进国企，银行，事业单位，考公务员等等，这些单位是必需要提供真实教育部认证的，办理教育部认证所需资料众多且烦琐，所有材料您都必须提供原件，我们凭借丰富的经验，快捷的绿色通道帮您快速整合材料，让您少走弯路。

→ 【关于价格问题（保证一手价格）】
我们所定的价格是非常合理的，而且我们现在做得单子大多数都是代理和回头客户介绍的所以一般现在有新的单子 我给客户的都是第一手的代理价格，因为我想坦诚对待大家 不想跟大家在价格方面浪费时间
对于老客户或者被老客户介绍过来的朋友，我们都会适当给一些优惠。
选择实体注册公司办理，更放心，更安全！我们的承诺：客户在留信官方认证查询网站查询到认证通过结果后付款，不成功不收费！

Profesores: Luis Rojas Miranda Nombre del alumno: PREGUNTA Nº 1 Tema: Máquinas Eléctricas Rotativas: Enumere los tipos de máquinas eléctricas rotativas que conoce, y señale el tipo de campo electromagnético respectivo; que se genera en el para su funcionamiento. PREGUNTA Nº 2 Tema: Principios de electro magnetismo: La operación de los motores eléctricos está basado en el principio de la fuerza electrodinámica o fuerza de Lorentz. En el dibujo dado (Fig.1) determine la dirección de las fuerzas en cada conductor (1 y 2) y escriba la ecuación que calcula el módulo de cada fuerza. Fig.1 Fig.2 PREGUNTA Nº 3 Tema: Principios de electro magnetismo: La operación de los generadores eléctricos se basa en la ley de la inducción electromagnética o ley de faraday. La generación de fuerzas electromotrices se puede obtener de dos formas: Por un campo variable sobre un conductor estático o por un conductor en movimiento sobre un campo estático. En el dibujo dado (Fig.2) determine la dirección de la fuerza electromotriz en cada conductor (1 y 2) y escriba la ecuación que calcula el módulo de cada fuerza electromotriz. PREGUNTA Nº 4 Tema: Circuitos magnéticos: Según la ley de Ampere para circuitos magnéticos y dado el circuito magnético de la Fig.3. Se pide determinar la ecuación que relaciona la intensidad magnética (H) a lo largo del contorno (l), con la fuerza magneto motriz (F). Fig.3 Fig.4 PREGUNTA Nº 5 Tema: Fuente de corriente alterna bajo carga: En el circuito mostrado en la Fig.4 (fuente monofásica bajo carga), se pide determinar las potencias S, P, y Q si solo se cierra uno de los interruptores; así mismo indicar el efecto sobre la tensión y la frecuencia (si aumentan, disminuyen o permanecen invariables para cada tipo de carga; 𝑋𝐿 = 𝑋𝐶 = 𝑟 = 10 𝛺, 𝑉 = 120 𝑉). ___________________ El Profesor del curso
