Examples
- The reliability analysis of ultimate strength of fpso hull girder under towing condition
的船体梁极限强度可靠性分析 - Fristly , according to the non - linear characteristics of twelve - phase rectifier , the thesis gives the calculation model for a short circuit in the subway traction power supply networks which provides the academic foundation for the design of the setting values and the simulation of protection . secondly , the thesis designs the dc feeder protection and control of subway , and gives the principle of setting accordingly , after it analysizes the characteristics of electric current under tow load and short circuit and considers severel factors . to validate the rationality of the design , the thesis simulates the transient electric current under two work conditions ( starting and passing the insulation ) ahd short circuit
其次，本文在详细分析地铁牵引负荷电流和馈线短路故障电流特点的基础上，考虑了直流保护系统设计应注意的几个因素，对地铁馈线保护与控制进行配置，给出了相应的保护整定原则，并针对某一地铁供电系统在详细分析了两种工况(机车起动与过分段绝缘)的电流暂态过程，得到了电流计算的数字模型，结合前面提出的短路模型，进行了地铁馈线保护的仿真，经仿真表明本文的保护设计是合理的。
