POLLUTION CONTROL RESEARCH INSTITUTE

To provide directional thrust to environmental control / protection activities, a Pollution Control Research Institute has been set up by BHEL at HEEP, Haridwar with the assistance of United Nations Development Programme (UNDP).

The main objective of the Institute is to develop technologies for pollution control in the areas of air, water noise and solid waste to obviate unintended side effects of economic growth. The Institute is concentrating on research and development activities related to environment protection against pollution emanating from industries. PCRI provides consultancy services related to pragmatic approaches / methods to maintain pollution within permissible limits. The other objectives include development of methods for recovery and recycling of industrial wastes.

Most modern facilities for monitoring and analysis in the area of air, water, noise and solid waste are available at the Institute. It has full-fledged computer facilities for prediction and forecasting pollution impact. It also has workshop and other support services.

The laboratories of Pollution Control Research Institute have been recognized by Ministry of Environment and Forests, Govt. of India; Department of Science and Technology, Govt. of India; Madhya Pradesh PradushanNivaranMandal; UP State Pollution control Board; Bihar State Pollution Control Board; Punjab State Council for Technology; Haryana State Pollution Control Board; Karanataka State Pollution Control Board.

Images of stator core

This is how a simple core looks like 

Copper Core

CONSTRUCTIONAL FEATURES STATOR CORE

I) Core 

Itconsists of thin laminations. Each lamination made of number of individual segments. Segments are stamped out with accurately finished die from the sheets of cold rolled high quality silicon steel.

Core after assembly

Before insulation on with varnish each segment is carefully debarred. Core is stacked with lamination segments. Segments are assembled in an interleaved manner from layer to layer for uniform permeability. Stampings are held in a position by 20 core bars having dovetail section. Insulating paper pressboards are also put between the layer of stamping to provide additional insulation and to localize short circuit.

Stampings are hydraulically compressed during the stacking procedure at different stages. Between two packets one layer of ventilating segments is provided. Steel spacers are spot welded on stamping. These spacers from ventilating ducts where the cold hydrogen from gas coolers enter the core radially inwards there by taking away the heat generated due to eddy current losses. The pressed core is held in pressed condition by means of two massive non-magnetic steel castings of press ring. The press ring is bolted to the ends of core bars. The pressure of the pressure ring is transmitted to stator core stamping through press fringes of non-magnetic steel and duralumin placed adjacent to press ring.

To avoid-heating of press ring due to end leakage flow two rings made of copper sheet are used on flux shield. The ring screens the flux by short-circuiting. To monitor the formation of hot spots resistance transducer are placed along the bottom of slots. To ensure that core losses are within limits and there are no hot spots present in the core. The core loss test is done after completion of core assembly.

2) Core Suspension

Inner part of stator

The elastic suspension of core consist of longitudinal bar type spring called core bars. Twenty core bars are welded to inner walls of stator body with help of brackets. These are made up of spring steel having a rectangular cross section and dove-tail cut at tap, similar type of dovetail is also stamped on to stamping and fit into that of core bar dovetail. Thus offering a hold point for stamping core bars have longitudinal slits which acts as inertial slots and help in damping the vibrations.

 The core bars are designed to maintain the movement of stator core with in satisfactory limits.

                    Hydro 

5.0 INTRODUCTION

Depending on the type of prime mover used, synchronous generators have been divided into two categories:

• Hydro Generators
• Turbo Generators

5.1 HYDRO GENERATOR

It is an electric rotating machine that transforms mechanical power from a hydraulic turbine or water wheel into electric power. Another definition can be, a low-speed generator driven by water turbines.

Hydro generators may have a horizontal or vertical shaft. The horizontal units are usually small with speeds of 300–1200 revolutions per minute (rpm). The vertical units are usually larger and more easily adapted to small hydraulic heads. The rotor diameters range from 2 to 62 ft (0.6 to 19 m) and capacities from 50 to 900,000 kVA. The generators are rated in kVA (kilovolts times amperes). The kilowatt output is the product of kVA and power factor. The normal power-factor rating of small synchronous generators is between 0.8 and 1.0 with 0.9 being common. For large generators a rating of 0.9–0.95 is common with the machines able to operate up to 1.0 when the load requires. The generators may also supply reactive power.

The turbine shown in the Figure 5.1 has an adjustable blade propeller, typical of large, low-head units that are common on large river power plants. The water enters the turbine spiral scroll casing, falls down through the turbine, causing rotation, and empties into the river. The shaft transmits the rotation to the generator spider or hub and thence to the rotor rim and poles. The magnetic field of the rotor poles transmits the torque to the stator and changes the mechanical power to electrical power.
