The Modelling, Design and Analysis of Automatic Temperature Control of a Room from Indoor Radiator Power

Musa Imran — 2024-04-17

In today's technological age, automatic control
has become ubiquitous, with manual control of appliances
becoming a thing of the past. This research focuses on the
automated control of room heating systems which use
appropriate sensors to make the system sensitive to outdoor
temperature, occupancy, humidity, and user input, thereby
achieving optimal human comfort and response reliability.
The aim is to design a reliable control system with transient
and steady-state responses that reduce power costs, increase
integration, and improve the user experience, without
requiring the user to turn off or adjust the temperature.
Previous research has been done on efficient controllers to
maintain constant room temperatures based on room
temperature coefficients and advanced sensors. However,
these neglect user experience. This study works on design of
an efficient controller for a large sized room. The simulation
of a model room with a knob control system shows promising
results. While the current work does not take into account
actuator effects or computational fluid dynamics methods for
optimizing parameters, it provides a reasonable model with
positive results. This study could continue into completely
automated heating systems in homes and hospitals, by
integrating appropriate sensors and heating actuators,
allowing users to simply turn on a heater and never worry
about making adjustments, for a further seamless experience.

Iot Based Condition Monitoring System for Distribution Transformer

Abdul Salam Ruk — 2024-04-17

This paper presents a mobile embedded system that is designed and implemented to capture and record data, such as voltage, current, oil level, temperature, humidity, and total power of the transformer. Electrical networks in rely heavily on power transformers. As a consequence, dependability plays a key role. Power transformer maintenance is currently allocated by end users. In contrast, not many resources are available for online condition monitoring. A transformer's reliability and long life are the reasons for this. In light of this, online monitoring might be justified due to the failure costs that may be high.

Through a Wi-Fi Module, a transformer operator can ask any related parameter value of transformer health through the system, even if the operator is not physically present at the transformer site. When transformer parameters exceed predefined limits, this system sends alerts. Monitoring the operating point of single-phase transformers using Arduino and GSM is done remotely. A 16x2 line LCD also displays all proposed parameters. Data from transformers are acquired remotely using a module in this system. SMS messages are sent to the system from the GSM modem to monitor transformer health. A system such as this will ensure smooth operations and prevent transformer failures. To enhance transformer reliability and prevent losses, GSM technology will be used to monitor transformer health in real-time and provide reliable services to customers.

Design and Implementation of Automatic Solar Tracking and Positioning Using a Novel Sensor for a PV System

Adeel Ahmed Abro — 2024-04-17

Energy production has become a challenge for modern day engineers and researchers. The conventional, non-renewable, ways of producing energy are proving to be both insufficient and hazardous to the environment. Hence, a prudent solution is to shift to renewables. The most viable choice is solar energy as it is abundant and environment friendly. Solar energy is produced using silicon wafer based solar panels. Traditionally, solar energy was produced using static solar panels. This is a complication as the sun does not remain in normal to the solar panels all day. A solution, to actuate the panels. A similar approach is taken in this study where a dual axis solar tracking system is designed and implemented on a 2KW solar power system. The study starts off with modelling and controller design of the tracking system. Which is then followed by the design of lab mockups. LDR sensor is used as primary detection sensor in the first lab mockup, but the LDR has its drawbacks. Hence, a novel PV-panel based sensor assembly is designed and implemented in the second lab mockup. This system proved to be sufficient to be implemented on the final 2KW system. The main part of the sensor assembly design was the design of the differential shade. It is responsible for the detection of the sun at any given instance. A complete study regarding this design process was conducted and a final inner angle and dimension of the differential shade was acquired. The design, when implemented on the full-scale system, was fully functional and through a power test it was calculated that the dynamic system was able to produce an efficiency advantage of 5%.

Development and Control of an IOT-Based Smart Electricity Meter Using a Mobile Application

Muhammad Shahzad — 2024-04-17

This is about the development of a prototype model of a smart electricity cadence that can be covered and controlled through a mobile operation. The proposed smart cadence is designed to give real-time monitoring of home appliance energy consumption and allow users to manage their energy consumption through a mobile operation. A smart cadence consists of a microcontroller, wireless communication modules, a mobile operation, and a power force. The microcontroller collects data from detectors that are connected to home appliances and sends the data to the mobile operation via wireless communication modules. The mobile operation displays the voltage, current, and power value of each appliance and allows druggies to turn off the appliances. The results show that the proposed smart cadence is effective in monitoring and controlling the energy consumption of home appliances. A wireless protocol and power cadence chip allow the SEM to measure the quantum of electricity used to communicate data.

Evaluation of Measurement Uncertainty for Testing & Calibration laboratories as per ISO/ IEC 17025:2017 standard requirements

Muhammad Abdullah Tariq — 2024-04-17

Measurement uncertainty is a qualitative measure of measurand in addition to precision and accuracy. Estimation of uncertainty in measurement is one of the most important characteristics for demonstration of competence for testing and calibration laboratories accredited on ISO/ IEC 17025 standards. To ensure the metrological traceability, to have confidence in measurements and to produce valid results, laboratory must estimate uncertainty from all significant sources. Consequently, measurement uncertainty can have impact on decision rules, statement of conformity and risk associated while making decisions with reference to a standard or specification. This paper presents a concise guideline for estimation of measurement uncertainty for testing and calibration laboratories with focus on electrical whether accredited on ISO/ IEC 17025:2017 standards or planned to be achieve accreditation in future. Non-accredited electrical testing and calibration laboratories may adopt the procedure/ process to enhance acceptability, to ensure confidence in measurement results and as a part of good laboratory practices. Finally, authors presented their way of budgeting measurement uncertainty as an example which is being implemented in electrical testing laboratory.
