This document summarizes the results of multiple outdoor measurements and modeling of bifacial PV module performance. Outdoor measurements were taken of 12 PV modules in Lugano, Switzerland between 2014-2015. Models were developed and validated to predict cell temperature, irradiation, and power output. The best-fit models estimated bifacial module performance using two parameters for ground-reflected irradiance and could predict power within 4-5 Watts. Further work is needed to improve cell temperature modeling and optimize models for different tilt/azimuth conditions.

Robot that can solve a 3x3 Rubik's Cube using image recognition.এনামুল হক
This document summarizes a project to build a robot that can solve a Rubik's Cube using image processing and motors controlled by an Arduino board. The robot takes a picture of the scrambled cube with a webcam, processes the image in Python to determine the moves needed to solve it, and sends commands to the Arduino. The Arduino then controls two servo motors - one to push cubes and one to rotate layers - to execute the necessary rotations and solve the cube. The document outlines the proposed methodology, working procedure through image processing and motor control logic, and limitations of not having 360-degree rotation servos.

Study of the impact on the protection plan of a pv production integrated to t...IAEME Publication
This document summarizes a study on the impact of integrating a 5 MW photovoltaic production system on the protection scheme of a medium voltage grid. Simulations were performed for different fault scenarios on the grid with and without the PV system. The results showed that the PV system integration can cause unjustified operation of protections and disconnect the PV system unnecessarily. This is due to the bidirectional power flow and dynamics introduced by distributed generation. The protection scheme may need adjustment according to the penetration level of distributed PV resources to coordinate properly.

Single phase active power filtering method using diode-rectifier-fed motor driveAsoka Technologies
This paper presents a single-phase high power factor motor drive system with active power filter function. Since most of electrical equipment connected to the grid must comply with regulations regarding grid current harmonics, motor drive systems are generally equipped with Power Factor Corrector (PFC) which is comprised of power switches and reactive components, e.g., inductor and capacitor. The reactive components are bulky and increase the system cost especially in low-cost applications such as electrical home appliances. In this paper, a new motor drive algorithm which is capable of both driving a permanent magnet motor and filtering the harmonic currents produced by other non-linear loads belong to the system is proposed. Since the input current of the drive system is directly controlled by manipulating not the motor current reference but the output voltage reference of the inverter, it is possible to achieve exact and immediate control of the grid current. The effectiveness of the proposed algorithms is validated by experiments with a permanent magnet motor drive system.

Simplified svpwm algorithm for neutral point clamped 3 level inverter fed dtc...Asoka Technologies
In this paper, a simplified space vector pulse width modulation (SVPWM) method has been developed for three phase three-level voltage source inverter fed to direct torque controlled (DTC) induction motor drive. The space vector diagram of three-level inverter is simplified into two-level inverter. So the selection of switching sequences is done as conventional two-level SVPWM method.Where in conventional direct torque control (CDTC), the stator flux and torque are directly controlled by the selection of optimal switching modes. The selection is made to restrict the flux and torque errors in corresponding hysteresis bands. In spite of its fast torque response, it has more flux, torque and current ripples in steady state. To overcome the ripples in steady state, a space vector based pulse width modulation (SVPWM) methodology is proposed in this paper. The proposed SVPWM method reduces the computational burden and reduces the total harmonic distortion compared with 2-level one and the conventional one also. To strengthen the voice simulation is carried out and the corresponding results are presented.

This document describes the design of an operational amplifier (op-amp) with specific gain and slew rate specifications. The design process involves choosing an architecture, then designing the transistor sizes and compensation network. An existing two-stage op-amp architecture is adapted. Transistor widths and lengths are calculated to meet the gain of 20,000 V/V and slew rate of 20 MV/sec. The schematic is drawn and simulated. The output is as expected but cannot drive the load, so an output buffer is added to minimize delay for larger loads.

4) Lumped-parameter thermal models

Why thermal models?
• Some materials (e.g. wire insulators, magnets) get damaged at high temperatures
• Temperatures influence electrical and magnetic properties
19. SPIN Applicazioni Magnetiche www.spinmag.it
INPUT DATA: POWERS
Thermal models generally require power injections or withdrawals as inputs.
Powers Temperatures
Thermal
model
Power values can be obtained in several ways:
• Directly inserted by user as input data
• Evaluated by an electric circuit in Activate
(e.g. equivalent circuit of an IM)
• Read from a text file (e.g. “filename.csv”)

PARAMETRIZATION
In order to have a powerful tool for thermal modelling, the Activate model is fully
parametrized: user has to insert geometric and physical data as inputs.

Axisymmetric electromagnet
The basic idea is to radially and axially divide the electromagnet, forming annular sectors each
one with its own physical properties:

electromagnetic devices
(and other complex systems)
Electromagnetic behavior
Thermal behavior
Control aspects and mechanical coupling
• Models can be fully parametrized high flexibility
• Representation of reality through Modelica blocks fast simulations and small errors
• Great variety of blocks and solvers high flexibility
• Co-simulations better accuracy (at the expense of higher computational time)
