摘　　要：电解铝等高耗能产业对于能源需求较高,同时由于市场经济原因导致其对于生产成本的控制需求更加迫切。许多企业为了降低成本建立自备电厂,利用机组直供负载形式降低经营成本。机组孤网运行相比于公网运行存在较大区别,这带来了许多问题。本文以一火电机组直供负载为例,通过仿真分析了孤网系统运行中可能存在的问题,并提出了相应的解决手段。High energy consumption industries such as electrolytic aluminum have a voracious energy consumption demand,thus it is urgent to control the production cost due to the market economy.In order to reduce the cost,many enterprises set up their own power plants and reduce the operating costs by using direct load supply.Compared with the traditional network operation,the unit operation in isolated network is different from that in the public power grid and brings many potential problems.In this paper,taking a thermal power unit as an example,the possible problems in the operation of the isolated power grid are analyzed by simulation,and the corresponding solutions are proposed.
