HVDS CASE STUDY

As the distribution network is located far away from the sources of power generation and the other infrastructure of electrical power system. 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 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. 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. Now voltage drop can be estimated at various power factors and also at various temperatures of conductors. Due to this unplanned expansion in the system, the supply conditions were sacrificed to meet the required targets. Help Center Find new research papers in:

Distribution losses being major share of the system losses needs special attention for achieving remarkable reduction in loss figure. The details are as under in table 1 [1]. Thus required calculation of HT transformer losses are as under in table no. Click here to sign up. So, there will be voltage drop, line losses and system reliability comes into the act. 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. 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.

Studies showed that the voltage drop, total impedance, sstudy efficiency and percentage regulation on the feeder are V, 4.

Installed capacity studu in Punjab IV. Long distance to supply loads causes a significant amount of voltage drop across the distribution lines. 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.

However, the consumers at the extreme end of the feeders have been experiencing low voltage levels. 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.

The power factor uvds to be used as 0. Pilferage hvdd HT system is assumed to negligible. The details are as under in table 1 [1].

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. Total power losses Skip to main content. The performance of the feeder may be improved by the HVDS system installation, which results in saving of hvfs losses per annum and an annual savings of The results obtained can be used for financial loss calculation and can be presented to regulate the tariff determination process.

Nuclear Power 20 nuclear reactors in operation, generating 5. Devi Lal State Institute of Engg. Therefore, loss minimization in power system has assumed greater significance HVDS scheme has led to the formulation of new strategy sstudy energy conservation and minimization of transmission and distribution losses by reducing the power theft.

Share from Central Sector Projects Calculations of power losses of 11kV 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. Estimation hvdz 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.

This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network. Determination of the proper placement and rating of transformers and feeders are the main objective of the basic distribution network.

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

This results in improving the stability as well as energy handling capacity of the system at minimum cost. Sarang Pande et al in [9] presented a paper, in which a method for energy losses calculation is presented. From the above calculations made, the net losses are turned out to be more in LT system and thus, LT arrangement is shifted to HT system by replacing large distribution transformers of kVA and kVA by transformers having smaller capacity of 10kVA and 15kVA for supplying power to these consumers without changing no.

Log In Sign Up. Soloman Nunoo et al in [4] presented a paper analysing the causes and effects of voltage drop on the 11KV GMC sub- transmission feeder in Tarkwa, Ghana.

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

Total losses per annum 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 stydy 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. But the weight of 80mm 2 conductor is Thus required calculation of HT transformer losses are as under in table no. Total load losses per annum units units 5.

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

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.
