Power System Control Revised Case Study

Interruption of power supply and its impact can have serious repurcussions on the production cycle, facilities, equipment performance and human productivity. Power outage management is a critical area were technology solutions are required to mitigate the impact of power outages. There are a number of measures available to minimize the possibility of occurrence of black outs, or, mitigate its adverse effects on important class of consumers.

Electric power system comprises components and systems like Generators, transformers, transmission lines and distribution networks, each of which is liable to be affected by insulation failure, due to over voltage or over load. They may also fail under normal service conditions owing to aging or poor quality of material or of manufacturing process. The conductors comprising the transmission and distribution network are also exposed to the elements like lightning, rain, wind, snow etc. which can cause short circuit faults or otherwise damage supporting structures. Insulation failure due to any of these causes lead to trip outs and other disturbances which at times be severe enough to culminate in wide spread power outages or black outs.

 

High Speed Conveying System As Applicable
To The Indian Plants

Generally the belt conveyors in the Indian Industries are low speed type with belt speeds in the range of 2 to 3 mps. There are few installations with speeds up to 4.5 mps. Most of the conveyors existing in India are short distance conveyors with length up to 1 km. There are few installations in the mines and ports with higher lengths. However, the speeds of the conveyors existing around the world are up to 9 mps. This paper discusses the merits and limitations of the high speed conveyors and the effect of higher speeds in the selection of the components.

This paper covers the aspects of the high speed conveyor system as applicable to the Indian Industry. Generally the belt conveyors in the Indian Industries are low speed type with belt speeds in the range of 2 to 3 mps. There are few installations with speeds up to 4.5 mps. Most of the conveyors existing in India are short distance conveyors with length up to 1 km.

 

Super Critical Steam Gen Technology

In the fossil fuel fired power plants successful operation of once through steam generator technology and drive to achieve higher thermal efficiencies made possible for the development of supercritical steam generators.The paper discusses key factors to the success of supercritical technology.

The Indian economy is growing in recent times at an average rate of 8.5% and a growth rate of about 8 to10 % is being forecast for the coming years, against a growth rate of about 5 to7% in the past years. To sustain the economic growth on continuous basis, reliable supply of electricity and availability of infrastructure shall be made available which are the key contributors. To augment the power demand, large capacity power generating units are being installed.

 

Wagon Loading And Unloading System

This paper covers the aspects of the wagon loading and unloading system currently in vogue in the Indian Industry. Generally the wagon loading systems are required in the mines and ports for loading the material into the wagons for further transportation to the process plants.

Two major types of wagon loading systems are (a) Rake will be stationary and loader will be moving (b) Rake will be moving and loader will be stationary.

 

Coal stockpile in Indian power

Managing the coal stockpiling system under environment-friendly conditions Information technology can effectively be used to virtually operate a number of power stations as a single unit to improve the plant performance, plant availability and cost of plant operation.

This paper presents the aspects of the coal stockpiles currently in vogue in the Indian Power plants and the suggested improvements. About 65% of the power generation in India is by coal based power plants. These coal based power plants are spread all over India viz. near the pit head, near the ports and in the interiors far away from the mines and ports. Most of the power plants have coal stockpile of capacities ranging from 7 days to 45 days requirement of the power plant.

 

CFBC SG TCE Paper

The requirement of high efficiency in power generation and environmental considerations, installation of power plants with Circulating Fluidized Bed Combustion (CFBC) technology with lignite as main fuel would be a techno economically viable option. This paper outlines the present status of CFBC technology and details of existing installations in India and abroad.

Within the past three decades, fluidised bed combustion (FBC) technologies have emerged as a commercially viable alternative, and becoming a technology of choice in many situations. These technologies have been applied to all solid fuels including biofuels, peat, lignite, coal, anthracite culm, coal washery wastes, petroleum coke, oil shale, municipal waste based fuels and an array of hazardous wastes. Many have been designed to co-combust several dissimilar solid fuels and wastes simultaneously.
