HVDS CASE STUDY

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. The installed capacity of electricity in the State increased from MW to to Isha Bansal et al in [10] presented a paper, in which it was presented to implement a distribution system having negligible losses, high quality of supply and reliability as the substantial amount of generated power is being wasted as losses. Total load losses per annum units units 5. The present paper emphasis on the re-designing for the existing distribution network for fulfilment of the above objectives of distribution feeder. Log In Sign Up.

Now voltage drop can be estimated at various power factors and also at various temperatures of conductors. 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. 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. Installed capacity generation in Punjab IV. The total installed capacity in India is Sub-transmission and distribution systems constitute the link between electricity utilities and consumers. For this purpose, two stage methodology is used.

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.

Estimation of Current at different power studdy On the basis of the current estimation at reference power factor of 0.

Total iron losses per annum units units 4. 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.

Thus required calculation of HT transformer losses are as under in table no. The results are satisfactorily obtained in the above case study, theoretically. The installed capacity of electricity in the State increased from MW to to 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.

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

Thus, the net power loss per stusy can be calculated as considering working for hours of 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.

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 present paper emphasis on the re-designing for the existing distribution network for fulfilment of the above objectives of distribution feeder.

Now voltage drop can be estimated at various power factors and also at uvds temperatures of conductors. 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 Calculations of power losses of studt Ganga Nagar Road Feeder The size of conductor used in the 11kV feeder, which is 30 and 20mm 2 and the resistance for this particular conductor is 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.

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.

Sub- transmission and distribution systems constitute the link between electricity utilities and consumers. This results in improving the stability as well as energy handling capacity of the system at minimum cost. Total power losses per annum Help Center Find new research papers in: Click here to sign up. 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.

Calculative Analysis of 11kV Distribution Feeder. Soloman Nunoo et al in [4] presented a paper analysing the causes and effects of voltage drop on hvss 11KV GMC sub- transmission feeder in Tarkwa, Ghana. 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.

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

So, there will be voltage drop, line losses and system reliability comes into the act. For this purpose, two stage methodology is used. 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. Sarang Pande et al hvfs [9] presented a paper, in which a method for energy losses calculation is presented.

The total installed capacity in India is Studdy paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network. Installed capacity generation in Punjab IV.

Devi Lal State Institute of Engg. 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.

As the distribution network is located far away from the sources of power generation and the other infrastructure of electrical power system. 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.
