Abstract
A computer algorithm for optimal voltage controlwith voltage regulators, suitable for large radial distribution networksis given in this paper. An objective function concerning thetotal cost of the voltage regulators (investment and maintenancecost) as well as the cost of losses of the examined networks is developedand constitutes the base of the algorithm. This algorithmmakes the initial selection, installation and tap setting of the voltageregulators, which provide a smooth voltage profile along the network,utilizing former ....etc

INTRODUCTION
A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Water is a useful and cheap medium for transferring heat to a process. When water is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gunpowder. This causes the boiler to ....etc

Design of Voltage Regulator
A transformer is a device with two or more stationary electrical ckt that are conductively disjointed but magnetically coupled by a common time-varying magnetic Field. Transformer are basically passive device for transforming voltage and current one of the windings, generally termed as secondary winding, transformer energy through the principal of mutual induction and drivers power to the wad. The voltage level at primary and secondary windings are usually different and any increase or decreas ....etc

Many analog systems need a stable power supply voltage that does not vary with temperature and time in order to operate properly. In a battery operated system the battery voltage is not stable, e.g. it decreases with decreasing temperature and with ageing. In that case a voltage regulator must be used, that regulates the battery voltage and generates a stable supply voltage to power other circuitry. 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 p ....etc

1. DISTRIBUTION SYSTEM

1.1 General description of Distribution System:

Distribution system is that part of the electric power system which connects the high voltage transmission network to the low voltage consumer service point

In any distribution system the power is distributed to various uses through feeders, distributors and service mains. Feeders are conductors of large current carrying capacity which carry the current in bulk to the feeding points. ....etc

A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches
Abstract
A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc
