“…Заслуживает внимания переход с PTC (Parabolic Trough Collector) на централизованную приемную систему -CRS (Central Receiver System) с комбинированным циклом -СС (Combined Cycle). Новая конфигурация объемного приемника солнечной башни CRS позволяет парогенератору рекуперации тепла -HRSG (Heat Recovery Steam Generator) эффективнее работать в режиме нагрева, что значительно повышает КПД электростанции [7].…”

At high ambient temperatures, the performance of gas turbine power plants drops significantly. Technical solutions of compensation for losses associated with the constant injection of water into the air intake of a gas turbine. This approach is not acceptable in regions with limited fresh water reserves. Radical solutions are required to reduce the cost of generated energy. Integrated Combined Solar Cycle (ISCCS) technology has proven itself on many projects. The addition of a combined cycle gas cycle with solar energy can significantly increase the overall efficiency of the power plant. Despite the increase in costs during the construction of its solar part, the total cost of operating solar collectors is several times less than a turbine installation. Given the global trend to fight carbon emissions, switching to a hybrid scheme is economically attractive. Trading in carbon credits for CO2 emissions will significantly reduce the payback period for the construction of gas turbine modernization under the ISCCS scheme. This paper presents an option to modernize a gas turbine power plant in the city of Basra (Iraq), using the advantages of solar radiation and recycling of combustion products from gas turbines. It is proposed to equip the existing 200 MW gas turbine plant with two steam turbine units with a capacity of 75 and 65 MW, working in conjunction with solar collectors producing low pressure water vapor. Due to modernization, the efficiency of the power plant should increase from 38% to 55%. The revision of the schematic and technical solutions of Iraq power plants will allow producing sufficient energy for the region.

“…In the other case, the air at the compressor exit is pre-heated by the solar tower before entering the combustion chamber. An alternative configuration has been proposed by Amani et al [31], the solar tower is used to heat up the exhaust gas from the gas turbine which are sent to the HRSG unit. Okoroigwe and Madhlopa [29] provided a review of integrated combined cycle coupled with a solar tower.…”

In this study, a simplified calculation method to evaluate the thermodynamic performance of two solar tower power plants of 50 MW is proposed. The systems consist in an open air Brayton cycle and a Brayton-Rankine combined cycle. The electricity produced, the average annual efficiency of the heliostats field-receiver system, the efficiency of the thermodynamic cycle and of the entire plant have been determined for both systems. The performances of the two plants have been compared to conventional plants using molten salts. The analysis shows that both systems have better performances than conventional solar tower plants using molten salts. The specific annual electrical energy per square meter of heliostat is higher than that obtained for the plant using molten salts, by 11.5% and 38.7% for the Brayton and the Brayton-Rankine combined cycle respectively. Moreover, an economic analysis has been performed. The results show that a reduction of the Levelized cost of Electricity (LCOE) can be achieved compared to the traditional molten salt plants, with savings of 15% and 13.6% for the Brayton and combined cycle respectively.
