均匀布料的控制方法在120t转炉中的应用

120t转炉下料方式采用均匀布料的控制方式,通过建立数学模型,智能计算下料时间、下料重量,比较模型数据和实际数据后按照下料时间比例、料重比例,分步多批次、小批量的加入矿石等料种,实现档位的自动调节。系统避免了因一次性大量下料引起喷溅和热量损失,提升了钢水合格率。

Control strategy of hybrid fuel cell/battery distributed generation system for grid-connected operation

This paper presents a control strategy of a hybrid fuel cell/battery distributed generation (HDG) system in distribution systems. The overall structure of the HDG system is given, dynamic models for the solid oxide fuel cell (SOFC) power plant, battery bank and its power electronic interfacing are briefly described, and controller design methodologies for the power conditioning units and fuel cell to control the power flow from the hybrid power plant to the utility grid are presented. To distribute the power between the fuel cell power plant and the battery energy storage, a neuro-fuzzy controller has been developed. Also, for controlling the active and reactive power independently in distribution systems, the current control strategy based on two fuzzy logic controllers has been presented. A Matlab/Simulink simulation model is developed for the HDG system by combining the individual component models and their controllers. Simulation results show the overall system performance including load-following and power management of the HDG system.
