Gaoya dianqi输电电缆线路运行电流较大，电缆支架涡流损耗和温升的问题被广泛关注，急需寻找一种损耗小、温升低、经济性能良好的支架材料。文中采用多物理场耦合的有限元分步仿真计算方法对220 kV电缆线路的钢、不锈钢和新型玄武岩复合材料支架的涡流损耗和温升进行计算。首先在频域下计算涡流损耗，之后再以涡流损耗作为热源，在瞬态下进行电磁场—温度场—流体场三场耦合计算，从而计算出支架温度分布。该方法在保证计算精度的前提下极大降低了计算的复杂度。计算结果表明：钢支架涡流损耗远大于不锈钢支架和玄武岩支架的涡流损耗。电缆电流为1 ...

Research on Channel Coding in Underwater Acoustic Communication Combined with OFDM Technology
, 2005 正交频分复用（OFDM）技术是一种多载波数字调制技术，它是一种实现高速无线数据通信的良好方法。在无线通信领域中，OFDM技术得到广泛的应用并成为第三代移动通信的主流技术。然而，将OFDM技术应用于水声通信中，在国内的研究尚处于起步阶段。水声信道是一个极其复杂的时间－频率－空间变化，强多径干扰，带宽有限且噪声干扰严重的信道，在这样的信道环境下实现通信系统的高速、可靠传输是极具挑战性的。OFDM系统中插入保护间隔后，若符号定时同步的起始时刻落在保护间隔内，则可以避免ISI并减小ICI，然而 ...

Gaoya dianqi箝位电路损耗计算是IGCT-MMC换流阀电气设计、运行损耗评估，以及阀冷却系统设计的基础。在分析IGCT-MMC子模块箝位电路工作原理的基础上，基于IGCT关断电流及二极管反向恢复电流的指数函数模型，建立了子模块换流暂态过程箝位电路的等效模型，提出了子模块箝位电路损耗的解析计算方法。对比试验测量和理论计算结果，验证了所提出损耗计算方法的有效性。
