### HVDS CASE STUDY

At power factor 0. So, we require the economical way to provide the electrical energy by State Electricity Boards to various consumers at minimum voltage drop and reduce the regulation of voltage. Pilferage on HT system is assumed to negligible. 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. 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. The results are satisfactorily obtained in the above case study, theoretically. 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.

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. Electric power providers have a duty to ensure that the consumers are always supplied with the required voltage level. The results obtained can be used for financial loss calculation and can be presented to regulate the tariff determination process. 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.

Thus, the net power loss per annum can be calculated as considering working for hours of a day with days per annum. 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 caze to supply the power to the consumers at the end point of each section.

Help Center Find new research papers in: The technical losses are the losses occurred in the electrical elements during of transmission stuudy energy from source to consumer and mainly comprises of ohmic losses. So, there will be voltage drop, line losses and system reliability comes into the act.

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

Calculations of power losses of 11kV Ganga Nagar Road Feeder The size of conductor used atudy the 11kV feeder, which is 30 and 20mm 2 and etudy resistance for this particular conductor is 0. Total power losses This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network. Devi Lal State Institute of Engg. The total installed capacity in India is 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.

Estimation of Current in feeder lines On the basis of the data of feeder, the calculation of current flowing through the feeder lines can be calculated as under in table 4. Distribution losses being major share of the system losses needs special attention for achieving remarkable reduction in loss figure.

Nuclear Power 20 nuclear reactors in operation, generating 5. Enter the email address you signed up with and we’ll email you a reset link.

Total load losses per annum units units 5. 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 hvdds period is carried out alongwith the complete comparison of LVDS and HVDS system of 11kV feeder. 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.

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. For this purpose, two stage methodology is used.

Share from Central Sector Projects The feeder voltage and feeder current are two constraints which should be within the standard range. 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 power factor assumed to be used as 0. Total transformer losses per units units annum 6. HVDS system is the most effective method in reducing the technical losses and improving the power gvds of supply in power distribution network.

The details are as under in table 1 [1]. Skip to main content. 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. 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.

Power losses in LT arrangement for each consumer by evaluating their corresponding line lengths of feeder and current values as shown in table no. 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.

The installed capacity of electricity in dase State increased from MW to to Total losses per syudy Long distance to supply loads causes a significant amount of voltage drop across the distribution lines.
