HVDS CASE STUDY

Determination of the proper placement and rating of transformers and feeders are the main objective of the basic distribution network. Sarang Pande et al in [9] presented a paper, in which a method for energy losses calculation is presented. 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. However, the consumers at the extreme end of the feeders have been experiencing low voltage levels. The installed capacity generation in Punjab is as shown in table 2 [2]. Total power losses

Qureshi et al in [6] presented a paper in his research to develop and guide lines for distribution engineers to show that by reducing the energy losses of the distribution systems available capacity of the system may be conserved without outing up additional capacity. 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. Total power losses Calculative Analysis of 11kV Distribution Feeder. 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.

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 hvvs and this high impedance is caused by poor jointing and terminations, use of undersized conductors and different types of conductor materials etc. 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.

However, the consumers at the extreme end of the feeders have been experiencing low voltage levels. Pilferage on HT system is assumed to negligible. This results in improving the stability as well as energy handling capacity of the system at minimum cost.

  BDVS CASE STUDY

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.

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. Log In Sign Up. The results are satisfactorily obtained in the above case study, theoretically. Power losses in LT arrangement for each consumer by evaluating their corresponding line lengths of feeder and current values as shown in table studh. Remember me on this computer.

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

Estimation of Current in feeder lines On the basis of the data of feeder, the calculation cade current flowing through the feeder lines can be calculated as under in table 4. 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 stydy. Studies showed that the voltage drop, total impedance, percentage efficiency and percentage regulation on the feeder are V, 4.

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.

The power factor assumed to be used as 0.

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. Sub-transmission and distribution systems constitute the link between electricity utilities and consumers.

At power factor 0. 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.

  HOLIDAY HOMEWORK TAFS

This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network.

So, the restructuring of existing LVDS as HVDS presents one of the best technically feasible and financially viable method for providing the reliable and quality supply to the customers. 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 Electric power providers have a duty to ensure that the consumers are always supplied with the required voltage level.

Sarang Pande et al in [9] presented a paper, in which a shudy for energy studg calculation is presented. 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 energy conservation and minimization of transmission and distribution losses by reducing the power theft. The total installed capacity in India is Devi Lal State Institute of Engg.

Total load losses per annum units units 5. The feeder voltage and feeder current are two constraints which should be within the standard range. wtudy

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. This work was mainly focused on low voltage distribution system LVDS.
