摘要
针对目前电力电缆故障模拟装置培训系统受动态电缆阻抗影响而导致故障电压模拟不精准的问题,设计了电力电缆故障模拟装置培训系统。设计电力电缆线路连接示意图,模拟不同线路路径及周围环境,并通过点击位域前景来实现人机交互中重合闸的选择。设计绝缘底板,用于安全模拟电缆断线故障、高阻故障、低阻故障及短路故障,并通过分析阻抗值模拟故障,以实现电力电缆故障模拟装置培训系统设计。通过仿真试验与基于互层电流的方法和基于半波傅氏算法的方法作对比。由仿真结果可知,所设计系统模拟的断路故障、短路故障、低阻故障、高阻故障的数据与实际故障数据一致。这说明所设计系统能够满足各类故障模拟,达到仿真培训需求。该系统在一定程度上能突破空间限制,可真实再现电力电缆故障环境,并为电力电缆故障的分析培训提供参考依据。
The power cable fault simulation device training system is designed to address the problem of inaccurate fault voltage simulation due to the dynamic cable impedance.The power cable line connection schematics are designed to simulate different line paths and surrounding environments and realize the selection of reclosing in human-computer interaction by clicking on the foreground of the bit domain.The insulated base plate is designed for safe simulation of cable break fault,high resistance fault,low resistance fault and short circuit fault,and simulate fault by analyzing impedance values to realize the design of power cable fault simulation device training system.Simulation tests are performed for compared with the method based on mutual layer current and the method based on half-wave Fourier algorithm.From the simulation results,the designed system can be seen that the data of the system simulated break fault,short circuit fault,low resistance fault and high resistance fault are consistent with the actual fault data.It proves that the designed system can meet all kinds of fault simulation and achieve the simulation training requirements.To a certain extent,the system can break through the spatial limitation,truly reproduce the power cable fault environment,and provide a reference basis for the analysis of power cable fault training.
