摘要
本文推导了电力系统电磁暂态仿真软件ATPDraw中三相输电线路的分布参数模型,给出了暂态解的求解过程。基于该分布参数模型对由空载线路合闸引起的操作过电压及其补偿措施进行了仿真计算,并结合实际对仿真结果进行了分析,验证了模型的正确性,从而ATPDraw为研究输电线路的过电压及设备选择提供了一种有效的仿真工具。
The distributed parameter model of three - phase transmission line in the power system electromagnetism transient emulation software ATPDraw is made and the calculation process of its transient solution is introduced in this paper. Based on this model, an emulation computing on the switching overvoltage caused from close on no load transmission lines and its compensation measures are made, its results also is analyzed combining the practice, and the exactness of this model is also verified, so that the ATPDraw would be an effective emulation tool used for studying overvoltage of transmission lines and selecting equipments.
