摘要：
分析了某天然气输气抢修站场的冷、热、电负荷，提出了采用天然气膨胀发电装置回收天然气余压并计算了发电量，设计了基于天然气分布式能源和天然气余压发电的多能互补系统。实现了天然气余压资源100%回收利用，天然气分布式能源系统综合能源利用效率超过80%，节能率超过25%。
Abstract：
Analyses the cooling, heating and power loads of a natural gas transmission and repair station, proposes the use of natural gas expansion power generation device to recover excess pressure of natural gas and calculates the power generation, and designs a multi-energy complementary system based on natural gas distributed energy and natural gas excess pressure power generation system. Realizes the recovery and utilization of natural gas excess pressure resources by 100%. The integrated energy utilization efficiency of the natural gas distributed energy system and the energy saving rate exceeds 80% and 25%, respectively.
Keywords:natural gas, excess pressure, distributed energy, multi-energy complementarity, integrated design
