Project Report for Investigation Of Alternators Subjected To Different Loads And Minimization Of Encountered Harmonics

In these days the maintaining appropriate power quality had became a basic concern in both production and transmission of the electrical energy, because of increasing demand for electricity and involvement of sensitive devices in transmission of power had caused many problems in distribution and utilization of the electrical energy, these sensitive devices in order to meet the increasing demand of electricity, they creating undesirable quantities like harmonics, the harmonics are created due to the non linear behavior of the load, causing severe problems in the electrical equipment either reducing its performance abilities or by damaging it permanently.  These power quality disturbances are to be reduced in order to achieve proper economical energy transmission.

In our project we provided we studied the different conditions of the alternator performance when they subjected to varying loads, along the suitable harmonic filtration methods improving power quality.  This paper gives the detailed information regarding the evolution of harmonics and their prevention strategies,

In order to analyze the performance of particular machine the following factors are to be concerned like voltage regulation, total harmonic distortion(THD), power factor variations, our paper discusses about the  harmonic analysis which helps in designing proper harmonic filters,  we  conducted experiments on two types of alternators one is Laminated rotor alternator and the other  Solid rotor alternator, and these alternators tested under varying loads i.e. current is proportional to the voltage  and non varying loads i.e. current is not proportional to the load,

The performance tests we conducted are includes oscilloscope test for observing the variations in the load characteristic, Synchronous Impedance Method, Ampere-turn Method, Zero power factor (or) Potier reactance method to find the voltage regulation, and to measure the harmonics we use Spectrum analyzer having two types namely Analog spectrum analyzer, Digital spectrum analyzer with a Wave analyzer to amplitude and frequency calculations. The filters we employed are Single tuned harmonic filter, Capacitor filter having tendency to provide information regarding various harmonics and their behavior.

Final Year Electronics Project Abstract for GSM Based SCADA Project

Introduction to GSM Based SCADA Project:

SCADA (supervisory management and information acquisition) usually refers to industrial management systems (ICS).

The term SCADA typically refers to centrally set systems that monitor associated management entire sites what is more as advanced systems that detached over large areas (anything from a structure to a nation).

ICS are laptop systems that monitor and management industrial infrastructure and facility primarily based processes in ways that describe below:

Industrial processes embrace those of producing, production, power producing, fabrication, and purification, and might run in nonstop, group, repetitive, or separate modes.

Infrastructure processes could also be public or personal, and embrace water handling and distribution, waste matter assortment and management, oil & gas pipelines, electric power broadcast and distribution, wind farms, protection warning systems, and enormous communication systems.

Facility processes occur each publicly facilities and personal ones, as well as structure, airports, and area stations. They observe and management HVAC, contact, and energy utilization.

The term SCADA usually refers to centrally set systems that monitor and management entire sites similarly as advanced systems that detached over massive areas (anything from an plant to a nation).

Most of the system is controlled mechanically by RTU’s and powerful microcontrollers.

This project introduces a complicated system mistreatment GSM technology whereby observation and dominant is completed through SMS’s from a certified itinerant.

SCADA systems usually implement a distributed info, ordinarily cited as a tag info, which contains information parts known as tags or points.

Some extent represents one input or output price monitored or controlled by the system.

Points are often either “hard” or “soft”. A tough purpose represents AN actual input or output at intervals the system, whereas a soft purpose results from logic and math’s operations applied to alternative points. 

We will style a RTU comprising a microcontroller interfaced with a Temperature device for temperature and a digital display for display.

ADC0804 is connected to a MICROCONTROLLER. This project principally deals with superior management and information acquisition of temperature management parameters like heat and cold to manage the temperature.
