Implentation on hvdc from different sources supplies by using mulitplier circuits
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryIn this contemporary world HVDC enables secure and stable asynchronous interconnection of power networks that operate on different frequencies. In addition, HVDC provides instant and precise control of the power flow .The scheme is intended & created to progress a HVDC of about 2KV commencing an input AC supply source of 230V using the capacitors and diodes that are assembled in the form of ladder network centered on voltage multiplier idea. Usually transformers are used for stepping up of voltage in which the output of the secondary of the step up transformer rises the voltage besides declines the current. On other hand by using voltage multiplier circuit which converts AC to DC for stepping up the voltage minimizing the use of transformers. These Voltage multipliers are principally used to improve high voltages somewhere low current is mandatory. The notion of developing HVDC from different sources like ac and renivalbe sourc is designated in this work which can be boosted up to about 10KV. For protection drive this work is delimited by means of a multiplication element of 8 so that the output would be surrounded by 2KV
Project Objectivesthe main objectives of projects are
- the main objective of project is to transmit dc power in secondary distrubation side in pakistan the dc poweer is transmitted at higher voltage at primary transmision side
- we design the project on basis that a village can be power by their own sources like solar panels and small kv genrators that run differnet fuel and these smal genrate voltage first convert into dc then step up to 10 kv by using multiplier circuit easily and they can powerr the whole smal town
- replacement of transformer by step uping dc through capacitors
- IPPs wil share their power thorugh dc transmision line avoiding the use of transformers
The main process of this experimental implementation for combine the high voltage .We can make the HVDC up to 1kv by means of single phase AC supply. It contains of rectifier circuit which changes AC supply into DC, amplifier circuit that amplifies the transformed DC power[10]. The voltage multiplier circuit of ladder network converts AC to a higher DC voltage level and potential divider through 10:1.when 230volt ac is complete to rectifier.
Generally rectifier is changing AC to DC. This distended voltage is agreed to the voltage multiplier circuit, and the electrical energy multipliers phase up moderately low power into tremendously elevated power standards. Because of such circuit, that the voltage across each stages of cascade is identical to twice the peak input v. (i.e. V max=2*v max). The elevated energy is make to get-together of multiplier course is extremely elevated. So it don’t need a quantity by unassuming voltmeter .Thusmeans of 10:1 potential divider output voltage is amount
solar panel output is also stepup throgh ladder circuit and then asynchrosily operate these outputs at single bus bar (transmision line)
Benefits of the Projectthe benfits of proejct are
- the project is based on dc system by step up the voltages by ladder and multiplier circuit in secondary side distrubution ( industrail and customer ) so their is no use of trnasformer ac power is transmited in dc
- IPPs can supply the power to different smal towns by smal genration stations and thorugh renivable source by stepup voltages and trnasmit
- minimum loss of energyby transmiting in dc as campared to transmison loss due to ac and transformer loss
