Design of electrical power supply of city Jičín

By Pavel Vánský

Abstract

The thesis deals with the issue of voltage changes or changes in the supply of electric energy of the particular town. The work entitled "Design of electrical power supply of city Jičín" addresses the specific case of unification of the town of Jičín. The first part describes the current state of distribution equipment, including calculations of short-circuit conditions, cross sections, a description of the sites of electricity consumption and the power consumption of the town. From the detailed description of the current state it is clear that most of the equipment is beyond its mean time to breakdown and has been in operation longer than intended. The next chapters describe possible solutions to reconstruction of the facilities. The first option – marked as option A – aims to maintain the existing 10kV distribution lines. Option B presents a solution in the form of abolition of urban transformation and transition to the 35kV voltage level (which is the voltage level used in the CEZ Distribution plc, eastern area). A comparison of proposed options is made in the technical-economic evaluation. The evaluation brings a detailed description of progress of implementation and planning of the reconstruction of facility particular parts for individual years. The conclusion summarizes the results of the technical-economic assessment of both options and gives reasons why option B, which proposes transition to the 35kV voltage level, is more advantageous
