摘要
母线排的动稳定性指标对于电力系统的稳定运行有着重要的意义,基于解析法的母线排动稳定性分析方法有着参数显示表达、计算速度快的特点;首先研究单对母线排在直流和交流条件下的电动力解析计算公式;在此基础上,研究多对母线排之间电动力的解析计算方法,进而分析其动稳定性。以某型号励磁系统中母线排为例,使用推导的解析计算公式分析其动稳定性;建立有限元模型进行验证,将解析计算结果和有限元仿真数据进行对比,证明了此方法的有效性,对于工程现场快速分析与定性设计计算具有实用价值。
The dynamic stability of busbar plays an important role in the safe operating of excitation system. Analytical method for busbar dynamic stability has the characters of parameter explicit expression and high calculation speed. The electro-dynamic force analytical formulas for single pair buses are first deduced under DC and AC current. After that, the electro-dynamic force calculation method of multi pair buses and its stability are analyzed. Take buses in a certain type of excitation system as an example, the analytical method is adopted to calculate the electro-dynamic force, and a finite element model is set up to compare with the results. The validity of this method has been verified and it is valuable for project on-site fast calculation and qualitative design calculation.
