HVDS CASE STUDY

HVDS CASE STUDY

Electric power providers have a duty to ensure that the consumers are always supplied with the required voltage level. The details are as under in table 1 [1]. This paper demonstrates the capability of load factor and load loss factor to calculate the power losses of the network. Total power losses 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.

For this purpose, two stage methodology is used. Long distance to supply loads causes a significant amount of voltage drop across the distribution lines. 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 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. 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. 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.

Total losses per annum The installed capacity generation in Punjab is as shown in table 2 [2]. Electric power providers have a duty to ensure that the consumers are always supplied with the required voltage level.

The results are satisfactorily obtained in the above case study, theoretically. At power factor 0. Thus, the net power loss per annum can be calculated as considering working for hours of a day with days per annum.

  THE PRICE WE PAY ESSAY BY ADAM MAYBLUM SUMMARY

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. But the weight of 80mm 2 conductor is Studies showed that the hhvds 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. 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.

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.

Skip to main content. Pilferage on HT system is assumed to negligible. 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. This work hvrs mainly focused on low voltage distribution system LVDS. Total power losses per annum The installed capacity of electricity in the State increased from MW to to Sarang Pande et al in [9] presented a paper, in which a method for energy losses calculation is presented.

The details are as bvds in table 1 [1].

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. 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 installation of HVDS system in stkdy area of the sub-division, is the main technique which is also fase in the present work to evaluate the proposed re-designing of existing distribution network and its future planning. Distribution losses being major share of the system losses needs special attention for achieving remarkable reduction in loss figure. Due to this unplanned expansion in the system, the supply conditions were sacrificed to meet the required targets. Total transformer losses per units units annum 6.

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

The total installed capacity in India is Thus, the distribution sectors require economical system to provide caxe energy at a suitable prize and at a minimum voltage drop to reduce the voltage regulation. The results obtained can be used for financial loss calculation and can be presented to regulate the tariff determination process.
