The performance of the proposed technique was simulated on the electromagnetic transient program , emtdc . the results of simulating show that the technique is effective and robust 本文在大型電磁暫態(tài)仿真軟件emtdc的平臺上進(jìn)行了大量仿真,仿真結(jié)果驗(yàn)證了該方法的正確性。
In this thesis we use electromagnetic transient program ( emtp ) to simulate and study those two kinds of overvoltage ; and research how to use moa and rc devices to reduce them basing on multi - exponential moa model and principle of rc device . at the same time , based on l - r damping principle , researches are made on the feasibility of restricting overvoltage by l - r device . thus methods of ensuring the parameters of these devices are concluded 本文利用電磁暫態(tài)計(jì)算程序( emtp )對上述兩種過電壓進(jìn)行了模擬計(jì)算研究;同時(shí),基于moa多指數(shù)模型和rc裝置原理研究了如何使用moa和rc裝置來對過電壓進(jìn)行限制;基于l - r阻尼原理探討了使用l - r裝置限制過電壓的可行性;并得出了以上保護(hù)裝置的參數(shù)確定方法。
