Integration And Performance Analysis Of Solar Energy And Power Station Based On Aspen Plus

For seeking an effective approach to save the energy and protect the environment, the integrated electricity generation of solar supported coal-burned power generation is studied according to our energy situation.First,the models for simulation of power plant thermal system,solar thermal system and integrated system are developed by applying the Aspen Plus software.Taking the 200MW power station and the direct steam generation parabolic troughs as objects,the simulation and the analysis are given.Then, from the perspective of thermal economic,some performance indexes of the integrated systems which are different of the integrated position are calculated by using the sensitivity analysis tool of the Aspen Plus on the base of the models.The best way of the integration is achieved by the comparison and analysis of the indexes results.To complete the integrated system design,the area of the solar collectors is calculated. Finally,the performance of the integrated power generation is analyzed as the preliminary study when the temperature of solar steam is changed.
