In this thesis a voltage regulator to be used in a battery operated system has been designed which meets the given specification of stability and power capabilities. A voltage reference, which is a commonly used devise in analog circuits, was also designed. The role of a reference voltage in an electrical system is the same as for a tuning fork in a musical ensemble; to set a standard to which other voltages are compared.

Voltage Regulators

The function of the voltage regulators is to maintain a relatively constant voltage level within limits set by the electric utility. All the distribution stations have a Single-phase voltage regulators which is very important for providing
reliable power to the customers. the range of loading conditions tends to change the transmission voltage level which is then adjusted by the voltage regulators by increasing or decreasing the difference in the voltage level from
the transformer to the distribution circuits. A maximum of 10% ..................[:=> Show Contents <=:]

The acquisition of statistical data on a power system is a necessary part in its operation and planning. The essential information, such as average daily load curve and maximum demand is often derived by a combination of pulse summation and computer analysis. A microprocessor based system has been developed which captures and analyses voltages and currents on feeders and produces a set of reduced data which fully describes the recent load pattern locally in the substation. Such a system is described by F.S.Schroder and K.C.Kwong.
The load on a power system is characterised by the fact that it..................[:=> Show Contents <=:]

Abstract This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. The functional structure for SVC built with a Thyristor Controlled Reactor (TCR) and its model are described. The model is based on representing the controller as variable impedance that changes with the firing angle of the TCR. A Power System Computer Aided Design /Electromagnetic Transients including DC (PSCAD/EMTDC) is used to carry out simulations of the system under study and detailed results are shown to access the performance of SVC on the voltage stability of the system...................[:=> Show Contents <=:]

Due to sinusoidal current flowing through in a primary winding a flux almost sinusoidal is produced in the iron whole of waveform as shown above.
If supply frequency is ?F? then the frequency of supply will also ?F?

So time to complete 1 cycle = 1/F sec.
So time to complete Quarter Evolutions = 0.25 x 1/F
