摘要
在中性点不接地配电系统中,由于电磁式电压互感器(TV)的励磁电感具有非线性特性,在一定条件下容易发生铁磁谐振现象,对系统的安全稳定运行产生严重的影响。文章对中性点不接地系统中电磁式电压互感器铁磁原理及其带来的危害进行了简要的分析介绍。在对现有的各种消谐措施的原理以及各自存在的优缺点简要介绍的基础上,对改进的消谐措施以及现有的组合式的消谐措施进行详细的介绍,并提出系统需要根据具体的情况选择合适的消谐方式或者组合式的消谐措施。
In the neutral ungrounded distribution system,since the excitation inductance of electromagnetic voltage transformer(TV) has nonlinear characteristics,and the ferromagnetic resonance phenomenon are prone to occur under certain conditions,which has serious influence on safe and stable operation of the system. This paper gives a brief analysis and introduction of electromagnetic voltage transformer ferromagnetic principle and its harm in neutral un-grounding system. In the principle of the existing various harmonic elimination measures and their respective advantages and disadvantages are briefly introduced,on the basis of harmonic elimination measures for improvement and the existing combined harmonic elimination measures is introduced in detail,and put forward that the system needs to choose the right means of harmonic elimination or combined harmonic elimination measures according to the specific situation.
