Effectiveness of High Voltage in Distribution System:High Voltage Distribution System

This paper presents the comparison of existing low voltage distribution system with proposed high voltage distribution system. The study is based on a real low voltage feeder in J&K state. The investigation is carried out to determine the losses in the existing low voltage (LT) distribution system and then converting this low voltage distribution system to proposed high voltage distribution system (HVDS) including bifurcation of load and replacing the one large transformer with various transformers of small rating. Since loss reduction in distribution system is of keen importance and main reason behind these losses is the use of low voltage for distribution in existing system. As for the low voltage in existing distribution system, current is high which leads to high power losses and also allow the hooking and hence power theft. This paper aims at reducing losses by using LT less or less LT ‘HVDS’ system and then determining the reduction in losses in terms of units and annual savings in terms of rupees due to proposed method. To check the feasibility of the proposed work, the annual saving and payback period of the proposed method is also determined.
