Functions of SCADA (Supervisory Control and Data Acquisition) The supervisory control and data acquisition systems allow a few operators to monitor the generator. The following are the functions of SCADA. 1. Data Acquisition : It...
Point to Point Links The simplest transmission link is a point to point links line that has a transmitter on one end and a receiver on the order. This type of link places the least demand on optical fiber technology and thus sets...
Methods of Voltage Control Methods Voltage control level is accomplished by controlling the generation, absorption and reactive power flow at all levels in the system. The following are the methods of voltage control. By...
Structures for InGaAs To improve the performance of structures for InGaAs APDs, various complex device architectures have been devised. One widely used structure is the separate-absorption-and-multiplication (SAM) APD...
Introduction Reactive Power and Voltage Control A power system is said to be well designed if it gives a good quality of reliable supply. Voltage level maintained within reasonable limits is referred as good quality. If reactive...
Introduction to Alternator Voltage Regulator Excitation System When the load on the power system changes, alternator voltage regulator the terminal changes. Therefore, to maintain the terminal voltage of the generator excitation...
Introduction – Electrical Machine Design Electrical machine design involves application of science and technology to produce cost effective, durable, quality and efficient machines. Also the machines should be designed as...
Automatic Voltage Regulator The function of an electric power system is to convert energy from one of the naturally available forms to electrical form and to transport it to the points of consumption automatic voltage...
Sensors and Transducers Sensors transducers are devices which produce proportional output signal (mechanical, electrical magnetic, ctc.) when exposed to a physical phenomenon (pressure, temperature, displacement, force, etc.)...
