Abstract: This paper is a survey of recent researches on the hardware design of heliostat in center solar receiver and modes of con2
trol. It is pointed out that the most difficult in controlling heliostat lies in bywhich way to realize the real time and efficient track of the
sun, including how to design the arrangement of heliostat field, the workingmode in differentweather condition, and so on. In addition,
some characteristics about the control strategies of controlling way are raised. At last the overall solution is introduced.
Key words: heliostat; solar power tower system; solar thermal power generation
