The feeder voltage and feeder current are two constraints which should be within the standard range. The power factor assumed to be used as 0. Now voltage drop can be estimated at various power factors and also at various temperatures of conductors. The proposed case study includes the conversion of existing LVDS into HVDS in order to minimise the distribution losses and pilferage thereby, improving the voltage profile and quality of supply to the consumers in existing 11kV feeder. Log In Sign Up. This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network. Nuclear Power 20 nuclear reactors in operation, generating 5.

Total losses per annum The total installed capacity in India is Thus, this sector especially, 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. Estimation of Current at different power factor On the basis of the current estimation at reference power factor of 0. Thus, the net power loss per annum can be calculated as considering working for hours of a day with days per annum. 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 In 1st stage, the power losses including the theft and losses in the line and transformer losses for both LT and HT systems are determined and then in 2 nd stage, determination of annual savings and payback period is carried out alongwith the complete comparison of LVDS and HVDS system of 11kV feeder.

Thus, this sector especially, 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. The results obtained can be used for financial loss calculation and can be presented to regulate wtudy tariff determination process. The results are satisfactorily obtained in the above case study, theoretically.

# Case Study: High Voltage Distribution System (HVDS) Implementation in BESCOM and MGVCL

The present paper emphasis on the re-designing for the existing distribution network for fulfilment of the above objectives of distribution feeder. Estimation of Current at different power factor On the basis of the current estimation at reference power factor of 0. Calculative Analysis of 11kV Distribution Feeder. Thus core and copper losses occurred in 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.

Help Center Find new research papers in: Therefore, loss minimization in power system has assumed greater significance HVDS scheme has led to the formulation of new strategy of energy conservation and minimization of transmission and distribution losses by reducing the power theft. The installation of HVDS system in considerable area of the sub-division, is the main technique which is also applied in the present work to evaluate the proposed re-designing of existing distribution network and its future planning.

Generation Total capacity till 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. Installed capacity generation in Punjab IV.

This results in improving the stability as well as energy handling capacity atudy the system at minimum cost. Thus, the net power loss per annum can be calculated as considering working for hours stydy a day with days per annum.

From the result, it is also realised that the causes of voltage drop on the feeder was mainly due to high impedance level as compared to the permissible value and this high impedance is caused by poor jointing and terminations, use of undersized conductors and different types of conductor materials etc.

Nuclear Power 20 nuclear reactors in operation, generating 5. Ritula Thakur et al in [3] presented a paper analysing and designing with the observation that the existing feeder is to be operated on 0. The subdivision is working on the installation of HVDS system in this feeder and calculations made above is an attempt for success of the above work made by State Electricity Board. Sub- transmission and distribution systems constitute the link between electricity utilities and consumers.

In fact, it has become essential ingredient for improving the quality of life and its absence is associated with poverty and poor quality of life. Pilferage on HT system is assumed to negligible. Total load losses per annum units hvvds 5. Thus required calculation of HT transformer losses are as under in table no. Total power losses Sub-transmission and distribution systems constitute the link between electricity utilities and consumers.

This work was mainly focused on low voltage distribution system LVDS. As the distribution network is located far away from the sources of power generation and the other infrastructure of electrical power system.

But the weight of 80mm 2 conductor is The power factor assumed to be used as 0. Total iron losses per annum units units 4. Due to this unplanned expansion in the system, the supply conditions were sacrificed to meet the required targets.

The performance of the feeder may be hvrs by the HVDS system installation, which results in saving of total losses per annum and an annual savings of LT Transformer losses As per the information derived from the 33kV State Electricity board of subdivision, on LT side, a large number of transformer of capacity of kVA is used to supply the power to the consumers at the end point of each section.

The technical losses are the losses occurred in the electrical elements during of transmission of energy from source to consumer and mainly comprises of ohmic losses. The details are as under in table 1 [1].

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.
