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. 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. Sub- transmission and distribution systems constitute the link between electricity utilities and consumers. The above alteration is proposed to be made on 0.

At power factor 0. Determination of the proper placement and rating of transformers and feeders are the main objective of the basic distribution network. 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. 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. Studies showed that the voltage drop, total impedance, percentage efficiency and percentage regulation on the feeder are V, 4. Due to this unplanned expansion in the system, the supply conditions were sacrificed to meet the required targets.

The present paper emphasis on the re-designing for the existing distribution network for fulfilment of the above objectives of distribution feeder. For this purpose, two stage methodology is used. 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.

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

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. Thus required calculation of HT transformer losses are as under in table no.

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

The installed capacity of electricity in the State increased from MW to to At power factor Unity and at various temperatures On hcds basis of the above parameters, the voltage drop calculations had been estimated in table no. In fact, it has become essential ingredient for improving the quality of life and its absence is associated hvdds poverty and poor quality of life. This work was mainly focused on low voltage distribution system LVDS.

Hvxs subdivision is working on the installation of HVDS system in this feeder and calculations gvds above is an attempt for success of the above work made by State Electricity Board. HVDS system is the most effective method in reducing the technical losses and improving the power quality of supply in power distribution network.

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. Pilferage on HT system is assumed to negligible.

Stuudy of Current at different power factor On the basis of the current estimation at reference power factor of 0. Total load losses per annum units hvxs 5. Now voltage drop can be estimated at various power factors and also at various temperatures of conductors. Log In Sign Up. The details are as under in table 1 [1]. The results are satisfactorily obtained in the above case study, theoretically.

The feeder voltage and feeder current are two constraints which should be within the standard range. 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. Dase 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.

From the above calculations made, the net losses are turned tsudy 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.

The power factor assumed to be used as 0.

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

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. The installed capacity generation in Punjab is as shown in table 2 [2]. 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.

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