HVDS CASE STUDY

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. The above alteration is proposed to be made on 0. Distribution losses being major share of the system losses needs special attention for achieving remarkable reduction in loss figure. Thus required calculation of HT transformer losses are as under in table no. At power factor 0. 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.

Distribution losses being major share of the system losses needs special attention for achieving remarkable reduction in loss figure. The power factor assumed to be used as 0. This work was mainly focused on low voltage distribution system LVDS. 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. 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.

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.

The above alteration is proposed to be made on 0. Total iron losses per annum units units 4.

Share from Central Sector Projects Estimation of Current at different power factor Hvsd the basis of the current estimation at reference power factor of 0. So, there will be voltage drop, line losses and system reliability comes into the act. The results are satisfactorily obtained in the above case study, theoretically. 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.

Studies showed that studdy voltage drop, total impedance, percentage efficiency and percentage regulation on the feeder are V, 4. The feeder voltage and feeder current are two constraints which should be within the standard range.

Total power losses per annum 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. This is due to, in most cases, voltage drops is a major concern bvds low voltage distribution systems and not very particular about voltage drop in the high voltage sides leaving it unattended.

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

Sub-transmission and distribution systems constitute the link between electricity utilities and consumers. Efficient functioning of these segments of the electricity utility is essential to sustain the growth of the power sector and the economy of the country. 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. 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.

Total power losses The details are as under in table 1 [1]. 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.
