Power System Configuration for a Typical Smart Town Planning – A Case Study in Dholera Special Investment Region

Abstract

To realize the draft development plan of Dholera special investment region (DSIR), Gujarat government and Gujarat infrastructure development board (GIDB) have decided to adopt the concept and technique of prevailing model of town planning scheme in the Gujarat state. The widespread model of town planning scheme is a coherent chain to put into practice the development plan. The entire area of about 920 sq.km. of DSIR out of which 277 sq.km. which is to be developed will be divided into various sectors. Each sector will be treated as independent unit for the implementation of town planning scheme. In this project title, we have to analyse the power distribution of town planning-2 west (TP2W) which is to be fed from a reliable source. Area of TP2W is 44sq.km. approx. In this distribution we have to predict the number of substations, length of transmission lines, sub transmission lines, distribution feeders, ring main units (RMUs). Since the city is called smart, the entire power network will be underground (through cables) save, incoming transmission line of 400 kV and its interface with 400 kV underground cables near the boundary of SIR. Smart grid technology will be used for control and operations as well as for data acquisition. Assumption and calculation of various types of loads are required i.e. industrial, commercial and domestic loads. In actual practice the load we consider contains fraction of two or more types of loads. For e.g. if 'x' is a total load then it is possible that '0.4 x' is industrial, '0.3 x' is commercial and '0.3 x' is domestic. Similarly one has to calculate the load equation of each sector individually and convert it in to zones and make a final total. Finally the whole electrical system has been analysed with ETAP software. The results if conform to the assumption of the planned electrical power system, the same shall be considered for thesis presentation. This has been done till the desired output gained.
