Simulation and analysis of perturb and observe mppt algorithm for array using...Asoka Technologies
This paper presents the comparative analysis between constant duty cycle and Perturb & Observe (P&O) algorithm for extracting the power from Photovoltaic Array (PVA). Because of nonlinear characteristics of PV cell, the maximum power can be extract under particular voltage condition. Therefore, Maximum Power Point Tracking (MPPT) algorithms are used in PVA to maximize the output power. In this paper the MPPT algorithm is implemented using Ćuk converter. The dynamics of PVA is simulated at different solar irradiance and cell temperature. The P&O MPPT technique is a direct control method enables ease to implement and less complexity.

This letter develops a wireless charging system based on a novel orthogonal magnetic structure and primary-side power control to simplify the structure and reduce the weight of on-board pick-up for recharging the unmanned aerial vehicles (UAVs). The novel magnetic structure has a polarized transmitter with a flat U-type core and a perpendicular air-cored receiving coil, guaranteeing the magnetic flux operation space away from UAV body by coil structure itself and also reducing the weight of magnetic receiver. The power flow to the battery is controlled by the primary-side based on charging current and voltage feedback by pick-up. Simulations based on ANSYS Maxwell and experiments are carried out to validate the proposal. The weight of magnetic receiver is 130g. And the system can deliver 500W with a DC-to-Battery efficiency of 90.8%, meanwhile 10A constant current/50V constant voltage charging for 12S lithium-ion battery is achieved by the closed-loop system.
[February 2017 - Ph.D. Final Dissertation] Enabling Power-awareness For Multi...Matteo Ferroni
Power consumption has become a major concern for almost every digital system: from the smallest embedded devices to the biggest data centers, energy and power budgets are always constraining the performance of the system. Moreover, the actual power consumption of these systems is strongly affected by their current “working regime” (e.g., from idle to heavy-load conditions, with all the shades in between), which depends on the guest applications they host, as well as on the external interactions these are subject to. It is then difficult to make accurate predictions on the power consumed by the whole system over time, when it is subject to constantly changing operating conditions: a self-aware and goal-oriented approach to resource allocation may then improve the instantaneous performance of the system, but still the definition of energy saving policies remains not trivial as far as the system is not really able to learn from experience in real world scenarios.
In this context, this thesis proposes a holistic power modeling framework that a wide range of energy and power constrained systems can use to profile their energy and power consumption. Starting from the preliminary experience developed on power consumption models for mobile devices during my M.Sc. thesis, I designed a general methodology that can be tailored on the actual system's features, extracting a specific power model able to describe and predict the future behavior of the observed entity. This methodology is meant to be provided in an “as-a-service” fashion: at first, the target system is instrumented to collect power metrics and workload statistics in its real usage context; then, the collected measurements are sent to a remote server, where data is processed using well known techniques (e.g., Principal Components Analysis, Markov Decision Chains, ARX models, etc.); finally, an accurate power model is built as a function of the metrics monitored on the instrumented system. The generalized approach has been validated in the context of power consumption models for multi-tenant virtualized infrastructures, outperforming results from the state of the art. Finally, the experience developed on power consumption models for server infrastructures led me to the design of a power-aware and QoS-aware orchestrator for multi-tenant systems. On the one hand, I propose a performance-aware power capping orchestrator in a virtualized environment, that aims at maximizing performance under a power cap. On the other hand, I bring the same concepts into a different approach to multi-tenancy, i.e., containerization, thus moving the first steps towards power-awareness for Docker containers orchestration, laying the basis for further research work.

Unknown input observer for a novel sensorless drive of brushless dc motorsAsoka Technologies
In this paper, a novel motor control method is proposed to improve the performance of sensorless drive of BLDC motors. In the terminal voltage sensing method, which is a great portion of sensorless control, a precise rotor position cannot be obtained when excessive input is applied to the drive during synchronous operation mode. Especially in the transient state, the response characteristic decreases. To cope with this problem, the unknown input (back-EMF) is modelled as the additional state of system in this paper. Taking into account the disturbance adopted by the back-EMF, the observer can be obtained by an equation of the augmented system. An algorithm to detect the back-EMF of a BLDC motor using the state observer is constructed. As a result, a novel sensorless drive of BLDC motors that can strictly estimate rotor position and speed is proposed.

Reduced Sensor Based PV Array Fed Direct Torque Control Induction Motor Drive...Asoka Technologies
This paper aims at the design, control and implementation of a solar photovoltaic (PV) array fed speed sensorless direct torque control (DTC) of an induction motor drive (IMD) for water pumping in standalone as well as battery connected hybrid mode. This stator flux estimated by proposed flux observer, is used for speed estimation. A DC link current sensor is used to reconstruct the motor phase currents by modified active voltage vector. One voltage sensor for DC link voltage sensing and only one current sensor for DC link current sensing, are used in this system for standalone operation of the system. All other required quantities are estimated through these two sensed signals. The IMD is energized by a photovoltaic (PV) array, which is operated at maximum power point (MPP). A perturb and observe control algorithm with additional flow rate controller, is proposed for MPP, which tracks MPP throughout the operating range and provides the facility to control flow rate. The suitability of the system is judged through simulated results in MATLAB/Simulink as well as test results obtained on a prototype developed in the laboratory.

Dual-function PV-ECS integrated to 3P4W distribution grid using 3M-PLL contro...Asoka Technologies
This study proposes a single-stage solar photovoltaic energy conversion system (PV-ECS) integrated to a three phase four-wire (3P4W) distribution grid with dual-function capabilities, i.e. active power transfer and power quality (PQ) enhancement at the point of interaction (PoI). The PV-ECS system comprises of a solar photovoltaic array and a voltage source inverter (VSI), supplying active power (during daytime) to the distribution grid and connected single-phase and three-phase loads. Apart from transfer of power, the system also improves the PQ at the PoI by compensating reactive power and neutral current, attenuating harmonics, correcting power factor and balancing grid currents. During night, the VSI acts as a shunt active power filter mitigating PQ issues, thereby increasing the device utilisation factor. A three-phase magnitude-phase locked loop (3M-PLL) method is utilised to extract and estimate fundamental term of load currents and an incremental conductance algorithm is applied for maximum power point tracking. To demonstrate its effectiveness, the system is modelled and its performance is simulated on MATLAB and experiments are performed on a developed prototype in the laboratory.

Grid interactive solar pv based water pumping using bldc motor driveAsoka Technologies
This paper proposes a bidirectional power flow control of a grid interactive solar photovoltaic (PV) fed water pumping system. A brushless DC (BLDC) motor-drive without phase current sensors, is used to run a water pump. This system enables a consumer to operate the water pump at its full capacity for 24-hours regardless of the climatic condition and to feed a single phase utility grid when the water pumping is not required. The full utilization of a PV array and motor-pump is made possible in addition to an enhanced reliability of the pumping system. A single phase voltage source converter (VSC) with a unit vector template (UVT) generation technique accomplishes a bidirectional power flow control between the grid and the DC bus of voltage source inverter (VSI), which feeds a BLDC motor. The VSI is operated at fundamental frequency, which minimizes the switching loss. The maximum power point (MPP) operation of a PV array, and power quality improvements such as power factor correction and reduction of total harmonic distortion (THD) of grid are achieved in this system. Its applicability and reliability are demonstrated by various simulated results using MATLAB/Simulink platform and hardware implementation.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

AVERAGING
The first step in designing a battery management system (BMS) is to develop a high fidelity battery model. In order for a BMS to estimate the battery critical parameters such as the battery state of charge and state of health, an accurate battery model has to be implemented on board of the BMS along with a robust estimation strategy. So a battery model is a list of mathematical equations that describe what’s physically happening inside the battery. In simple terms, as shown in the figure, if we apply the same current profile to the battery and the battery model, both should generate the same voltage profile and the error between the two signals should be close to zero. The model can predict the behavior of the battery in a way that if we applied an estimator, we can predict critical parameters such as the battery SOH and remaining useful life.
The Open-circuit voltage (OCV) is the difference of electrical potential between two terminals of a device when the device is disconnected from any circuit. There is no external load connected and no external electric current flows between the terminals.
The Open Circuit Voltage (OCV) represents a Voltage Source's Full Voltage, since there is no voltage drop across the load. A voltage source's OCV represents its full voltage value, since the source does not share any of its voltage with a load.
The unconnected voltage is real voltage, even if a voltage source is unconnected and not attached to any load, the potential power still exists.
- So in case of batteries, if you measure the voltage of the battery terminals with a multi-meter, you will read the OCV even if there is no current is flowing in the circuit.
- The battery OCV is particularly important since there is a relationship that exists between the battery State-of-Charge (SOC) and Open Circuit Voltage (OCV).
- There is a relationship between the battery Open-circuit voltage (OCV) and State of Charge (SOC). The relationship depends on the battery chemistry and the direction of charging and discharging. If you start with a fully discharged battery and start charging it, the battery OCV starts at let’s say 2.2V and keep ramping up following the red line until you reach the maximum voltage at 4.3V. The battery SOC is set to 100% when the battery is fully charged. As you start discharging the battery, you start from a fully charged state then you follow a different path indicated by the blue line until you fully discharge the battery at 0% SOC. The difference between the charging and discharging paths is due to hysteresis. In the following section we will know how to experientially derive the battery open circuit voltage-state of charge relationship from experimental data.
- The simple battery model is as shown in the figure, the voltage source represents the OCV which is function of the battery state of charge. Then, the battery charging and discharging internal resistance are reprensted as RChg and Rdis. By subtracting the voltage drop across the resistance from the battery OCV, you can calculate the battery terminal voltage V.
The battery internal resistance is function of the battery temperature, SOC and life.
- In the following section, we are going to simulate the simple battery model using MATLAB and Simulink.
