Abstract: An auxiliary steam supply system in a solar power plant includes a solar receiver having a superheater section, a turbine, a steam circuit, a thermal energy storage arrangement and an auxiliary steam circuit. The thermal energy storage arrangement, including a thermal energy storage medium, is configured for the steam circuit to receive a portion of the steam to heat the thermal energy storage medium. The thermal energy storage arrangement may receive the steam from any location across the superheater section. Moreover, the auxiliary steam circuit generating auxiliary steam flow, which thermally communicates with the thermal energy storage arrangement to be heated, is introduced to any location across the superheater section. Capacity of the thermal energy storage arrangement may be relatively small as compared to the solar receiver and may be compact for placement on top of a tower.

Abstract translation: 太阳能发电厂中的辅助蒸汽供应系统包括具有过热器部分，涡轮机，蒸汽回路，热能存储装置和辅助蒸汽回路的太阳能接收器。 包括热能存储介质的热能存储装置被配置用于蒸汽回路接收一部分蒸汽以​​加热热能存储介质。 热能存储装置可以从跨过过热器部分的任何位置接收蒸汽。 此外，产生与待加热的热能储存装置热连通的辅助蒸汽流的辅助蒸汽回路被引入跨越过热器部分的任何位置。 与太阳能接收器相比，热能存储装置的容量可能相对较小，并且可以紧凑地放置在塔顶部。
