HVDS CASE STUDY

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. 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. 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. 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. 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. Sub-transmission and distribution systems constitute the link between electricity utilities and consumers. The installed capacity generation in Punjab is as shown in table 2 [2].

So, there will be voltage drop, line losses and system reliability comes into the act. 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. This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network. Distribution losses being major share of the system losses needs special attention for achieving remarkable reduction in loss figure. Log In Sign Up.

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.

The results are satisfactorily obtained in the above case study, theoretically. 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.

Power losses in LT arrangement for each consumer by evaluating their corresponding line lengths of feeder and current values as shown in table sstudy. Calculative Analysis of 11kV Distribution Feeder. Long distance to supply loads causes a significant amount of voltage drop across the distribution lines.

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

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 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.

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. Help Center Find new research papers in: Devi Lal State Institute of Engg. Total power losses per annum Sub- transmission and distribution systems constitute the link between electricity utilities and consumers.

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.

Installed capacity generation in Punjab IV. 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. Total losses per annum Log In Sign Up. However, the consumers stidy the extreme end of the feeders have been experiencing low voltage levels.

But the weight of 80mm 2 conductor is 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.

So, we require the economical hvde to provide the electrical energy by State Electricity Boards to various consumers at minimum voltage drop and reduce the regulation of voltage. The details are as under in table 1 [1]. 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.

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

Share from Central Sector Projects Generation Total capacity till 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.

Nuclear Power 20 nuclear reactors in operation, generating 5.

So, there will be voltage drop, line losses and system reliability comes into the act. Due to this unplanned expansion in caase system, the supply conditions were sacrificed to meet the required targets.

The total installed capacity in India is 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.
