The purpose of the thesis is to consider the problem of electricity shortages in the Republic of Tajikistan and the development of hydropower for the purpose of solving this problem, as well as providing electricity to remote areas through the construction of hydropower plants in this area. The thesis addressed the design issues of the Sanobodskaya HPP on the Pyanj River and the power distribution scheme. The layout and composition of the waterworks facilities has been determined. Water and energy calculations have been carried out and the capacity of the hydroelectric power stations has been justified, amounting to 204 MW and the amount of electricity produced, which is set at 1,820 million kWh / year. Calculations were made to determine the parameters of the main power and auxiliary equipment and selected for this hydroelectric hydroelectric turbine (PO 230 with impeller diameter 1.60 m) and hydrogenerators of the type VGS 320 / 80-10 climatic modification one with a capacity of 42.5 MVA. A block diagram of electrical connections in the form of a reinforced block and a distribution device diagram with two busbar systems for the SF6 insulated-220 kV system are selected. The main electrical circuit of the hydroelectric station and its own power supply circuit have been developed. Transformers for this hydroelectric station were selected: three step-up transformers TDTs-125000/220-UHL1, two auxiliary transformers at the generator voltage of the TMN-6300/10 type, 8 pieces of transformers of the TSZA-400 / 10-82TZ type, which are connected to a 6 kV bus for aggregate own needs, two of them for redundancy and six pieces of TSZS-1000/10 type for station-wide ones. According to the main scheme, the calculation of short-circuit currents was made and, based on the results of the calculation, electrical equipment was selected (switches and disconnectors). An economic calculation was made, according to the efficiency of the designed object. |
