HVDS CASE STUDY

HVDS CASE STUDY

Thus, the net power loss per annum can be calculated as considering working for hours of a day with days per annum. This is due to, in most cases, voltage drops is a major concern in low voltage distribution systems and not very particular about voltage drop in the high voltage sides leaving it unattended. Skip to main content. Efficient functioning of these segments of the electricity utility is essential to sustain the growth of the power sector and the economy of the country. Thus, the distribution sectors require economical system to provide electrical energy at a suitable prize and at a minimum voltage drop to reduce the voltage regulation.

Total transformer losses per units units annum 6. HT Transformer losses As this HT system is replaced by smaller capacity of transformer of rating 10kVA and 15kVA for supplying power to the consumer and their no load and load losses are computed according to particular transformer. Calculation of voltage drop at various power factors and temperature As the values of current at various power factors had been determined as per above table. The present paper emphasis on the re-designing for the existing distribution network for fulfilment of the above objectives of distribution feeder. HVDS system is the most effective method in reducing the technical losses and improving the power quality of supply in power distribution network. Click here to sign up. As the distribution network is located far away from the sources of power generation and the other infrastructure of electrical power system.

For this purpose, two stage methodology is used.

So, there will be voltage drop, line losses and system reliability comes into the act. Long distance to supply loads causes a significant amount of voltage drop csse the distribution lines. The performance of the feeder may be improved by the HVDS system installation, which results in saving of total losses per annum and an annual savings of The details of transformers alongwith their specified ratings has been obtained from 33kV State Electricity Board of existing sub-division is as shown in table no.

The total installed capacity in India is Calculation of voltage drop at various power factors and temperature As the values of current at various power factors had been determined as per above table.

HVDS system is the most effective method in reducing the technical losses and improving the power quality of supply in power distribution network. Thus, the distribution sectors require economical system to provide electrical energy at a suitable prize and at a minimum voltage drop to reduce the voltage regulation.

At power factor Unity and at various temperatures On the basis of the above parameters, the voltage drop calculations had been estimated in table no.

Calculative Analysis of 11kV Distribution Feeder. Total load losses per annum units units 5. Total iron losses per annum units units 4. Czse of Current at different power factor On the basis of the current estimation at reference power factor of 0. The installation of HVDS system in considerable area of the sub-division, is the main studyy which is also applied in the casw work to evaluate the proposed re-designing of existing distribution network and its future planning.

Total power losses Remember me on hvda computer. Qureshi et al in [6] presented a paper in his research to develop and guide lines for distribution engineers to show that by reducing sudy energy losses of the distribution systems available capacity of the system may be conserved without outing up additional capacity.

The results are satisfactorily obtained in the above case study, theoretically. The installed capacity generation in Punjab is as shown in table 2 [2]. hvs

Total power losses per annum Total losses per annum The details are as under in table 1 [1]. Total transformer losses per units units annum 6.

In fact, it has become essential ingredient for improving the quality of life and its absence is associated with poverty and poor quality casw life. Nuclear Power 20 nuclear reactors in operation, generating 5. Power losses in LT arrangement for each consumer by evaluating their corresponding line lengths of feeder and current values as shown in table no. However, the consumers at the extreme end of the feeders have been experiencing low voltage levels.

Generation Total capacity till Due to this unplanned expansion in the system, the supply conditions were sacrificed to meet the required targets. Therefore, loss minimization in power system has assumed greater significance HVDS scheme has led to the formulation of new strategy of caase conservation and minimization of transmission and distribution losses by reducing the power theft. The technical losses are the losses occurred in the electrical elements during of transmission of energy hcds source to consumer and mainly comprises of ohmic losses.

Thus, the net power loss per annum can be calculated as considering working for hours of a day with days per annum. Share from Central Sector Projects The results obtained can be used for financial loss calculation and can be presented to regulate the tariff determination process. Thus core and copper losses occurred caes the transformer also contributed to the total power losses per annum in LT system So, for kVA rating transformer, the fixed value of no-load losses and full load losses are W and W respectively.
