基于储能的柴油发电机组效率提升研究

Research on Efficiency Improvement of Diesel Generator Unit Based on Energy Storage

大部分矿山企业由于地处供电网络难以覆盖或经济欠发达的无电地区,且用电负荷大,采用柴油发电机组孤网自供电模式,存在发电效率低、发电成本高、运维工作量大、环境污染等问题。利用储能系统的特点,结合海外矿山企业的需求,搭建新型的储能柴发供电网络,介绍了其网络架构、系统组成以及工作原理,并结合项目实例,说明基于储能的柴油发电机组实现了发电效率的显著提升,降低机组单位发电油耗,减少对环境的空气与噪声污染,实现节能减排、降本增效、绿色环保。

Most mining enterprises,with large electricity loads,are located in areas without electricity which are difficult to be covered by power supply network or economically underdeveloped,hence they adopt the isolated grid self-supply mode of diesel generator unit,bringing problems such as low power generation efficiency,high power generation cost,large operation and maintenance workload and environmental pollution.By making full use of the characteristics of the energy storage system and with a view to the needs of overseas mining enterprises,a new energy storage diesel generator power supply network was built,and its network architecture,system composition and working principle were introduced.In this paper,several project cases were given to illustrate that the power generation efficiency is significantly improved,the fuel consumption per unit of power generation is reduced,the air and noise pollution to the environment is reduced,which means that it can achieve energy saving with reduced emission,increased efficiency with reduced cost as well as more environment-friendly benefits.
