6~10 kV Line Overcurrent Protection Laboratory Simulation and Multisim Simulation Realization

基于6~10 kV线路过电流保护的基本原理,设计了在实验室条件下的现场模拟实现及在Multisim软件平台上的仿真实现.在实验室现场模拟设计中,以原理接线图-展开接线图-实验接线图的设计思路,进行设备选型及连接,制定了详细的设备清单及操作过程,并最终记录实验模拟数据.在Multisim软件平台仿真设计中,以现场模拟实验接线图为设计依据设计仿真电路,设备选型以功能呈现为重点,在不影响实际功能的前提下可适当调整设备连接结构,按照现场模拟操作顺序进行仿真实现.虚拟仿真实现必须基于实验室现场模拟数据,二者相互配合、取长补短才能达到较好的教学及学习效果.

Based on the basic principle of 6~10 kV line over-current protection,design the on-site simulation realization under laboratory conditions and the simulation realization on the Multisim software platform.In the laboratory field simulation design,the principle wiring diagram-expand the wiring diagram-the design idea of the experimental wiring diagram,equipment selection and connection,a detailed equipment list and operation process,and finally recorded experimental simulation data.In the simulation design of the Multisim software platform,the field simulation experimental wiring diagram is the design basis Design the simulation circuit,and the equipment selection focuses on the presentation of functions.The connection structure of the equipment can be adjusted appropriately without affecting the actual function,and the simulation can be carried out in accordance with the on-site simulation operation sequence.The realization of virtual simulation must be based on the laboratory simulation data,and the two cooperate with each other,Learn from each other to achieve better teaching and learning results.
