Novel Concept of Dish Stirling Solar Power Generation Designed With a HTS Linear Generator

A novel dish Stirling solar power generation (DSSPG) system has been designed incorporated with a high temperature superconducting (HTS) linear synchronous generator (LSG). The high efficient HTSLSG is a compact energy converter for a Stirling engine in the DSSPG system, where a duplex of Stirling cycles is applied, in which a Stirling engine replaces the conventional linear compressor forming a Stirling pulse tube refrigerator (SPTR). This paper presents the DSSPG system designed with the HTSLSG cooled by the duplex Stirling system, and analyzes the thermal load and power distribution in the system to provide bases for consideration of practical application. Analysis results show that the DSSPG system with the HTSLSG refrigerated by the SPTR powered by the DSSPG system itself can be realized, and has higher efficiency than that with the conventional LSG and has larger system capacity.
