A Comparative Study of Losses and Cost of Ac and Dc Collection Systems

Vishnu Kumar, Abhinav Sharma, Bharat Kumar


A specialized and financial examination is made amongst DC and AC accumulation frameworks of seaward wind ranches. DC gathering frameworks have the upsides of lessened weight and size of the DC links and DC links are free from receptive force pay. The substantial 50/60 Hz transformers in the seaward transmission stage of AC accumulation frameworks can be supplanted with littler size medium recurrence transformers in DC gathering frameworks. Notwithstanding, the requirement for a high power DC–DC converter with high voltage change proportions and DC assurance techniques will remain a test for the DC accumulation frameworks. Likewise, DC accumulation frameworks don't as a matter of course lessen the force transformation stages contrasted with The AC accumulation frameworks regardless of the possibility that HVDC (High Voltage DC) transmission is utilized to exchange the seaward wind power from the accumulation frameworks to the coastal networks. A cost evaluation study confirms that the taken a toll diminishments accomplished by the lessened size of the DC links and seaward stage are exceeded by the expense of DC defensive gadgets and DC–DC converters. This is on the grounds that the length of the DC gathering links is generally short contrasted with the long separation HVDC links. The specialized examination upheld by the reenactment results demonstrates that the aggregate misfortunes in the DC gathering frameworks are higher than in AC gathering frameworks. The impact of gathering transport voltages on the misfortunes is investigated for the DC accumulation frameworks.
