THEORETICAL SIMULATION INVESTIGATION OF THE PIONEER 1 MW SOLAR POWER TOWER SYSTEM IN CHINA
Preliminary results in predicting performance of the first 1 MW solar power tower system in China named “DAHAN locating in north-west of Beijing nearby The Great Wall are presented in this paper. DAHAN consists of collector system (CS), receiver system (RS), thermal storage system (TSS), steam generation system (SGS), electrical power generation system (EPGS) and the balance of plant (BOP). The plant is based on the Rankine cycle. The constant temperature of outlet flow is kept while the outlet mass flowrate depends on the CS output. Four different kinds of suggested fields were analyzed optically and thermally to determine the heliostat fields efficiency field η and the spillage loss spill η. TSS allows power generation to be shifted to periods of peak demand and provides a buffer between the plants receiver and turbine, allowing the turbine to operate during cloud-induced transients 1. Operational strategies and performance prediction associated with startup, normal operation and cloud transients were studied. Theoretic analysis method combined with optical and thermal coupling simulation under different operation cases were proposed. These results can be used to assess the impact of alternative plant designs or operating strategies based on the annual energy production.
