A Study of an FDTD‐Based Frequency‐Dependent Line Model for Electromagnetic Transient Simulations

NODA TAKU

摘要

SUMMARY >Electromagnetic transient (EMT) simulations of power systems require accurate representation of models in a wide range of frequencies. This of course applies to the representation of transmission lines, and the phase‐domain frequency‐dependent line model is often used to this end. The phase‐domain line model does not require modal transformation in EMT simulations but requires modal decomposition at its model identification stage, and there are cases where it fails to fix switchovers of propagation modes with respect to frequency. Thus, a frequency‐dependent line model which essentially avoids modal decomposition is desired. This paper studies the possibility of a frequency‐dependent line model based on the FDTD (Finite Difference Time Domain) method as a candidate which satisfies the above‐mentioned requirements. First, improvements regarding computational efficiency and numerical stability are made to Kordi's FDTD‐based frequency‐dependent line model. Then, the following points are clarified using the developed model: (i) Waveform deformations due to propagation modes with different velocities can be reproduced completely without modal decomposition; (ii) As the time step size becomes larger, waveforms obtained by the developed model become less accurate due to the embedded filter for numerical stability. These points assure, if the error due to the embedded filter is reduced, that the developed model can become a useful frequency‐dependent line model without model identification problems. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>摘要</ title> >电磁瞬态（EMT）电力系统的模拟需要在各种频率范围内精确表示模型。这当然适用于传输线的表示，并且相位域频率依赖的线模型通常用于此目的。相位域线模型不需要EMT模拟中的模态变换，而是需要在其模型识别阶段进行模态分解，并且存在在频率上未能修复传播模式的切换的情况。因此，期望基本上避免模态分解的频率相关线模型。本文研究了基于FDTD（有限差分时域）方法作为满足上述要求的候选的频率相关线模型的可能性。首先，对基于FDTD的频率依赖性线模型进行了关于计算效率和数值稳定性的改进。然后，使用开发的模型阐明以下几点：（i）由于具有不同速度的传播模式，可以完全再现由于具有模态分解的波形变形; （ii）随着时间步长变大，由于嵌入式滤波器，由开发模型获得的波形变得更加准确，因为嵌入式滤波器用于数值稳定性。如果减少了由于嵌入式过滤器引起的误差，则开发模型可以成为有用的频率相关线模型，而无需模型识别问题。</ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-22399/'>《Electrical engineering in Japan》</a> <b style="margin: 0 2px;">|</b><span>2018年第2期</span><b style="margin: 0 2px;">|</b><span>共10页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=NODA TAKU&option=202" target="_blank" rel="nofollow">NODA TAKU;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Electric Power Engineering Research Lab CRIEPI Japan;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1782.html" title="输配电工程、电力网及电力系统">输配电工程、电力网及电力系统;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=electromagnetic transient (EMT) simulations&option=203" rel="nofollow">electromagnetic transient (EMT) simulations;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=transmission and distribution lines&option=203" rel="nofollow">transmission and distribution lines;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=frequency‐dependent line model&option=203" rel="nofollow">frequency‐dependent line model;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=modal decomposition&option=203" rel="nofollow">modal decomposition;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=FDTD method&option=203" rel="nofollow">FDTD method;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=XTAP&option=203" rel="nofollow">XTAP;</a> </p> <div class="translation"> 机译：电磁瞬态（EMT）模拟;传输和配送线;频率依赖性线模型;模态分解;FDTD方法;XTAP;
