Basic Principles and Functions of Electrical Machines




INTRODUCTION
The Direct Current (D.C.) machine, the synchronous machine, and the induction machine are the major electromechanical conversion devices in industry . The merits of the squirrel cage induction machine are: lightness, simplicity, ruggedness, robustness, less initial cost, higher torque-inertia ratio, capability of much higher speeds, ease of maintenance, etc . The most important fe..............etc

BASIC INSTRUMENTATION MEASURING DEVICES AND BASIC PID CONTROL


INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter,
pressure, flow, level or temperature to name a few and supplying a signal
that is proportional to the measured parameter. The output signals are
standard signal and can then be processed by other equipment to provide
indication, alarms or automatic control. There are a number of standard
signals; however, t..............etc

Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating machines (SuperMotors and SuperGenerators) that can generically be categorized as SuperMachines. Compared to conventional machines of equivalent rating, these SuperMachines are expected to be less expensive, lighter, more compact, efficient, and provide significantly superior stable operation in a power system. The field windings are made with HTS conductor material (BSCCO, or Bi-2223) which operates at 35-40 K and can be cooled with inexpensive,..............etc

Fuel Cell Plant Concept with Dynamic Characteristics of a Rotating Generator


Abstract—Fuel cell plants will be powering future electrical
systems. Fuel cells normally generate direct current (DC) which
must be converted into Alternating Current (AC) for
transmission efficiency and for broader use by numerous loads of
different characteristics. An AC load consists of real power and
reactive power. The real power is generated by fuel cells.
However, the ..............etc
