Problems facing Power Industry in India

Problems facing Power Industry in India: The electricity requirements of Power Industry in India have grown tremendously and the demand has been running ahead of supply. Electricity generation and transmission processes in India are very inefficient in comparison with those of some developed countries. As per one estimate, in India generating capacity is utilized on […]

Uses of Computer and Microprocessors

Uses of Computer and Microprocessors: The first methos for solving various power system problems were AC and DC network analysers developed in early 1930s. AC analysers were used for load flow and stability studies whereas DC were preferred for short-circuit studies. Analogue computers were developed in 1940s and the Uses of Computer in conjunc­tion with […]

Power Systems Engineering

Power Systems Engineering: The Power Systems Engineering of the first decade of the twenty-first century has to face a variety of challenging tasks, which he can meet only by keeping abreast of the recent scientific advances and the latest techniques. On the planning side, he or she has to make decisions on how much electricity […]

Electromagnetic Radiation from Overhead Lines

Electromagnetic Radiation from Overhead Lines: Biological effects of electromagnetic radiation from power lines and even cables in close proximity of buildings have recently attracted attention and have also caused some concern. Power frequency (50 or 60 Hz) and even their harmonics are not considered harmful. Investigations carried out in certain advanced countries have so far […]

Environmental Aspects Of Generation of Electrical Energy

Environmental Aspects Of Generation of Electrical Energy: Conversion of one form of energy or another to electrical form has unwanted side effects and the pollutants generated in the process have to be disposed off. Pollutants know no geographical boundary, as result the pollution issue has become a nightmarish problem and strong national and international pressure […]

Distributed and Dispersed Generation

Distributed and Dispersed Generation: Distributed Generation (DG) using many small generators of 2-50 MW output, installed at various strategic points throughout the area, so that each provides power to a small number of consumers nearby. These may be solar, mini/micro hydel or wind turbine units, highly efficient gas turbines, small combined cycle plants, since these […]

Deregulation Meaning

Deregulation Meaning: For over one hundred years, the electric power industry worldwide operated as a regulated industry. In any area there was only one company or government agency (mostly state-owned) that produced, transmitted, distributed and sold electric power and services. Deregulation Meaning concept came in early 1990s. It brought in changes designed to encourage competition. […]

Energy Conservation Methods

Energy Conservation Methods: Energy Conservation Methods is the cheapest new source of energy. We should resort to various conservation measures such as cogeneration (discussed earlier), and use energy efficient motors to avoid wasteful electric uses. We can achieve considerable electrical power savings by reducing unnecessary high lighting levels, oversized motors, etc. A 9 W compact […]

Power Systems Growth

Power Systems Growth: Power Systems Growth – India is fairly rich in natural resources like coal and lignite; while some oil reserves have been discovered so far, intense exploration is being undertaken in various regions of the country. India has immense water power resources also of which only around 25% have so far been utilised, […]

Energy Storage Materials

Energy Storage Materials: There is a lot of problem in storing electricity in large quantities. Energy Storage Materials which can be converted into electricity can be stored in a number of ways. Storage of any nature is however very costly and its economics must be worked out properly. Various options available are: pumped storage, com-pressed […]
