Relays are employed in a power system network to ensure that the system operates safely, reliably, and conveniently. The Over-Current relay is commonly utilized in the power system to prevent against short circuits and incorrect system settings. In the power system, an incorrectly set Over-Current relay makes it harder to send the trip signal. As a result, it must be carefully linked in the power system. As a result, it is critical to certify the installation of power protection equipment. The o...

This report presents the study, design and making of a power electronic DC-DC converter powering a floodlight load. The wholes system makes up a MPPT solar charge controller. The report comprises of improvements from the first and second phase report. Specifications of solar panel, battery, load and converter are given. MATLAB software is a good choice for modelling and system control, due to that ability it has been selected to design and model the MPPT solar charger. This report shows a comple...

The following report explores the research and design of a 3-phase,25KVa, core-type, distribution transformer connected in a star-star configuration, for the purpose of stepping-down high voltages from electricity producers to make it useable for consumers. In order to go about the design process, extensive research on transformers, configuration types, as well as material choices was conducted, according to the design specifications provided. Once a thorough understanding of transformers was ga...

Safety being the major concern for working in the high voltage laboratory, the alternate is to simulate the hardware system using various circuit design software’s. Thus, in this paper, broad overview of various methodologies for the generation of both AC/DC impulse voltage, the method used to simulate circuits for the 2-stage cascade transformer and series resonant transformer is MATLAB Simulink where analysis and results obtained by analysing graphs after running the simulation. Comparison o...

The main aim of this section is to design sensing circuits for measuring both AC and DC voltages ranging from 0-100 VAC and VDC, and display the measured values using a basic ADC for Part A and for Part B using an internal ADC of a microcontroller.

In the world of technological progression, conventional resources of energy (fossil fuels, nuclear fuels, gas etc.) are at the edge of extinct. To overcome this problem, non-conventional energy sources (solar energy, wind energy, ocean thermal energy, biomass or biogas, geothermal, tidal energy etc.) play a vital role, in which solar energy is most important energy source, which produces electricity by the photovoltaic effect. Solar photovoltaic (PV) cells are used to convert solar energy into u...

The are 4 sequence that are designed and analyzed. the 4 sequences were chosen based on student number. This report has two section A and section B. i used protests simulation software to implement the design. components used are 7 segment displayer jkff and logit gates

The power system stability of synchronous machines is primarily concerned with transient behaviour, which is defined as the ability of a power system to maintain a state of operating equilibrium under normal operating conditions and to re-establish an acceptable state of equilibrium after being subjected to a disturbance. The main goal of this practical project is to examine synchronous machines' transient behaviour. The mathematical description, electrical transient performance, and electrical...
