摘要

为充分利用沼气能源,提高沼气发电能源利用率,提出利用温差发电片对沼气发电机组废热进行回收,利用Matlab/Simulink构建基于温差发电两级修正的沼气发电机组废热回收利用仿真模型,并通过实测数据对模型进行验证。结果表明,两级修正的温差发电模型平均绝对百分比误差（MAPE）为0.045%,二次修正相比于一次修正MAPE降低0.167%;加入温差发电装置后沼气发电系统能源利用率可提升8.59个百分点,废热利用效率可提升15.53个百分点。

Abstract

To make full use of biogas energy and improve the energy utilization rate of biogas power generation, this paper proposes to use thermoelectric generator to recover the waste heat of biogas generator sets. The simulation model of waste heat recovery and utilization of biogas generator sets based on two-stage correction of thermoelectric power generation is constructed by Matlab/Simulink, and the model is verified by measured data. The results show that the mean absolute percentage error（MAPE） of the two-stage modified thermoelectric generation model is 0.045%, and the second correction is 0.167% lower than the first correction mean absolute percentage error（MAPE）. After adding the thermoelectric generator, the energy utilization rate of the biogas power generation system can be increased by 8.59 percentages poimt, and the waste heat utilization efficiency can be increased by 15.53 percentages poimt.
