CSP parabolic trough heliostat, it means utilizing parabolic cylinder trough mirror to concentrate sunlight onto tubular heat collecting tube to generate high-temperature CSP power assemblies. CSP is a technology which converts solar radiation energy into heat energy by using heliostat for generation through thermodynamic cycle process and it can be divided into parabolic troughs, solar power tower and solar dish power systems. Correspondingly, the key parts in solar energy collecting device---heliostat, is also divided into parabolic trough, tower and dish ones, among which the parabolic troughs are the only ones going into commercialized operation for current CSP technology with most perfect technology and broadest application.
