ESTABLISHMENT OF VARIOMTER CALCULATION MODEL AND RESEARCH OF APPLICATION SOFTWARE

对电抗器进行了电磁原理和计算模型的分析,通过相关的电磁理论的推导,建立了一种新的计算电抗器电感量的计算模型,在此模型中采用了对铁心磁化曲线插值计算磁导率的方法,该模型能够针对电抗器的不同工作点计算出相应的电感量大小.对于铁心达到磁饱和后,本模型同样能够较准确的计算电感量.并在此基础上设计出了相应的计算电感量的C 语言软件和Visual Basic5.0 forWindow s

In the paper, some calculation inductance methods are analysed and sumed up. At the same time,electric magnet principle and calculation models are discussed. By deducing electric magnet principle correlated, a new calculation model is founded and it adopts calculation permeability by inserting value to magnetization curve. It can calculate inductance in different working points. When the core gets to saturation, the calculation is able to calculate the inductance.On the basis of the model, the C programme and Visual Basic 5.0 interface are is an example with power electronic technique using computer technique.
