Problems solved by technology

On the other hand, it is worth studying whether foreign technologies are directly copied over under the special climate conditions of our country. The current dish power plants are mostly located in areas with little or no wind, while areas with abundant sunshine in our country are often windy, strong winds and even sandstorms frequently occur. The applicability of direct copying is very questionable

Abstract

The invention discloses a solar disc type electricity generating light-gathering optical system which comprises a machine base support, a Stirling set support and a disc type reflector. The Stirling set support and the disc type reflector are installed on the machine base support through tracking rotation devices, a Stirling electricity generating set is installed on the Stirling set support, and a receiver for gathering solar energy heat and providing a heating source for the Stirling electricity generating set is installed on the Stirling electricity generating set. The solar disc type electricity generating light-gathering optical system is simple in structure, reasonable in design, convenient to achieve, high in stability and good in wind-resistant performance, can effectively and sufficiently use the solar energy resource, expands the solar application scope, and is low in achievement cost, good in using effect and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar dish type power generation concentrating optical system. Background technique [0002] Although foreign solar thermal power generation technology has developed rapidly in recent years, it is not a feasible move to introduce foreign tower or trough solar thermal power generation systems with huge sums of money. On the one hand, the foreign technology itself is not yet mature, and there are still difficulties in industrialization, and major technological breakthroughs are still awaited. The industrialization of solar thermal power generation still needs greater breakthroughs in key technologies, such as improving the efficiency of solar concentrating receivers and developing advanced heat storage technologies. On the other hand, it is worth studying whether foreign technologies are directly copied over under the special climate conditions of our country. The...
