英文摘要: Solar tower thermal power electricity-generation technology is a clean, environmentally friendly and renewable mode of power producation. This project focuses on the light-gathering and heat-accumulating subsystem which is a core apparatus of solar tower power plant. Based on the wireless network communication dispatching approach, utilizing the reginonal devision and hierarchical control technique, this project studies the simulation,control, and optimal distribution design of the heliostat field to achieve the energy optimal balance between the light-gathering and the heat-accummulating subsystem. Moreover,the key technical issues such as high accuracy sun-tracking, light-gathering control of large scaled heliostat clusters, thermal energy flow optimal distribution control of heat absorber on central tower are studied. This project will deliver algorithms for energy-balance and energy-efficient solar energy collection, which help the solar tower power plant running under finite investment cost and of great significance of theory and application.
