HVDS CASE STUDY

The feeder voltage and feeder current are two constraints which should be within the standard range. The power factor assumed to be used as 0. 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. 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 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.

Pilferage on HT system is assumed to negligible. 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. Total load losses per annum units units 5. Attachie and Franklin N. Total iron losses per annum units units 4. 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.

So, the restructuring of existing LVDS as HVDS presents one of the best technically feasible and financially viable method for providing the reliable and quality supply to the customers.

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

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

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. 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.

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

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. 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.

This results in improving the stability as well as energy handling capacity of the system at minimum cost. Estimation of Current at different power factor On the basis of the current estimation at reference power factor of 0.

Calculative Analysis of 11kV Distribution Feeder. Click here to sign up. Sub-transmission and distribution systems constitute the link between electricity utilities and consumers. 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.

At power factor 0. 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.

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 hvdz the distribution systems available capacity of the system may be conserved without outing up additional capacity. For this purpose, two stage methodology is used.

Electric power providers have a duty to ensure that the consumers are always supplied with the required voltage level.

Isha Bansal et al in [10] presented a paper, in which it was presented to implement a sfudy system having negligible losses, high quality of supply and reliability casse the substantial amount of generated power is being wasted as losses. The installed capacity of electricity in the State increased from MW to to 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.

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

So, there will be voltage drop, line losses and system reliability comes into the act. HVDS system is the most effective method in reducing the technical losses and improving the caes quality of supply in power distribution network. This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network.

Pilferage on HT system is assumed to negligible.

The power factor assumed to be used cqse 0. 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 total installed capacity in India is 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.
