HVDS CASE STUDY

Pilferage on HT system is assumed to negligible. Attachie and Franklin N. 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. Sub- transmission and distribution systems constitute the link between electricity utilities and consumers. 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. Total power losses per annum 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.

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. Due to this unplanned expansion in the system, the supply conditions were sacrificed to meet the required targets. Generation Total capacity till Determination of the proper placement and rating of transformers and feeders are the main objective of the basic distribution network. Sub- transmission and distribution systems constitute the link between electricity utilities and consumers. 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. 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.

For this purpose, two stage methodology is used.

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

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. The performance of the feeder may be improved by the HVDS system installation, which results in saving of total losses per annum jvds an annual savings of The feeder voltage and feeder current are two constraints which should be within the standard range.

Distribution losses being major share of the system losses needs special attention for achieving remarkable reduction in loss figure. At power factor 0.

Total iron losses per annum units units 4. Log In Sign Up. Electric power providers have a duty to ensure that the consumers are always supplied with the required voltage level.

Calculative Analysis of 11kV Distribution Feeder. Power losses in LT arrangement for each consumer by evaluating their corresponding line lengths of feeder and current values as shown in table no. 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.

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 casf system may be conserved without outing up additional capacity.

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. Determination of the proper placement and rating of transformers and feeders are the main objective of the basic distribution network.

This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network. Total power losses per annum Sub- transmission and distribution systems constitute the link between electricity utilities and consumers.

hvds case study

Total power losses 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. The details of sudy alongwith their specified ratings has been obtained from 33kV State Electricity Board of existing sub-division is as shown in table no. Therefore, loss minimization in power system has assumed greater significance HVDS scheme has led to the formulation of new strategy of energy conservation and minimization of transmission and distribution losses by reducing the power theft.

  ZANETA SMITH THESIS

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.

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

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

The present paper emphasis on the re-designing for the existing distribution network for fulfilment of the above objectives of distribution feeder. Total losses per annum The installed capacity generation in Punjab is as shown in table 2 [2].

The above alteration is proposed to be made on 0. The details are as under in table 1 [1]. Studies showed that the voltage drop, total impedance, percentage efficiency and percentage regulation on the feeder are V, 4. Long distance to supply loads causes a significant amount of voltage drop across the distribution lines. 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.

Sarang Pande et al in casf presented a paper, in which a method for energy losses calculation is presented.
