摘要
本文介绍三相桥式整流负荷产生特征谐波的原理,并给出其谐波电流模型和计算方法。应用此方法,可以较准确地计算由整流负荷引起的系统电压畸变。
The harmonic model of HVDC converter suitable for the computation of har- monic power flow with multi-harmonic sources is worked out.Given the 3-phase A.C.voltages and their harmonic voltages,the harmonic currents poured in to h e A.C.system from the converter are calculated.The program is made and the ontrast calculations between the harmonic currents with and without the 5th har- monic voltage on the converter bus are carried out.
