线路电脉冲除冰系统峰值电流仿真计算

Simulation Calculation of Peak Current of Line Electric Pulse Deicing System

为测算线路除冰电脉冲系统中不易直接测量的除冰脉冲力,将其转化为测算与之关联的线圈峰值电流,并验证电脉冲除冰方案的可行性。基于MATLAB软件对电脉冲系统中线圈的峰值电流进行流程建模、程序设计与仿真计算,并将所得结果与峰值电流的理论计算结果进行比较验证。结果表明,仿真计算得出的峰值电流值与理论计算值基本一致,随机误差不超过10%。通过对电脉冲系统的线圈峰值电流进行仿真计算可得出,随着脉冲放电电压的增大,与峰值电流对应的除冰脉冲力也会不断增大,可为之后在人工状态下进行输电线路电脉冲实验提供参考依据。

In order to measure the deicing pulse force that is not easy to measure directly in the electric pulse deicing system,it is converted to measure the coil peak current associated with it and verify the feasibility of the electric pulse deicing scheme.Based on MATLAB,the process modeling,program design and simulation calculation of the peak current of the coil in the electrical pulse system are carried out,and the results are compared with the theoretical calculation results of the peak current.The results show that the peak current value obtained by simulation is basically consistent with the theoretical value,and the random error is less than 10%.Through the simulation calculation of the peak coil current of the electric pulse system,it can be concluded that with the increase of the pulse discharge voltage,the de-icing pulse force corresponding to the peak current will also increase,which can provide a reference for the electric pulse experiment of the transmission line in the artificial state.
