According to the system and the method, light field arrangement can be performed automatically, arrangement results and selection of thermoelectric equipment can be optimized, and hourly on-grid energy of the power station can be accurately computed.

Description

technical field [0001] The invention relates to the technical field of photothermal power plant design, in particular to a design and optimization system and method for a trough-type solar photothermal power station. Background technique [0002] According to the "Twelfth Five-Year Development Plan for Renewable Energy", my country will select suitable locations in the Ordos Plateau of Inner Mongolia along the Yellow River flat desert, the Hexi Corridor flat desert in Gansu, the Turpan-Hami Basin and Tarim Basin in Xinjiang, Lhasa, Tibet, Qinghai, Ningxia and other places. Carry out the construction of solar thermal power generation demonstration projects. By 2015, the installed capacity of solar power generation will reach 21 million kilowatts, including 10 million kilowatts of photovoltaic power stations and 1 million kilowatts of solar thermal power generation. However, there is no design and optimization system for trough solar thermal power plants in China. In addition...

However, there is no design and optimization system for trough solar thermal power plants in China

In addition, since trough solar thermal power plants are affected by factors such as direct solar radiation (DNI), air temperature, and wind speed, it is very difficult to accurately calculate the hourly electricity consumption of solar thermal power plants
