摘要

相间功率控制器（IPC）与所连电网之间有发生参数谐振的风险，现有的技术措施为避免发生这一现象减小了IPC参数选择的取值范围。为揭示IPC与所连电网之间发生参数谐振的机理，建立了IPC的π型等值电路。指出，IPC与相连电网之间发生参数谐振的原因是其π型等值电路与所连电网中储能元件等值参数之间满足了谐振条件。IPC支路感抗和容抗参数的取值使得其π型等值电路中的3个阻抗参数是相连电网中储能元件等值参数的10倍及以上时，IPC与相连电网之间发生参数谐振的风险便可以大大降低。以一个含有IPC15的单机系统为例，对提出的参数选择方法进行了仿真验证，结果证明了结论的正确性。

Abstract

Risks of parametric resonance exist between interphase power controller（IPC）and the associated power grid. Existing approaches to avoid this phenomenon tend to reduce the range of parameters in IPC. To reveal the mechanism of parametric resonance between IPC and the associated power grid，theπ-type equivalent circuits of IPC are established. The reason of parametric resonance between IPC and the associated power grid is the parameters ofπ-type equivalent circuit and energy storage components in the associated power grid satisfying the resonance conditions. Because the three impedance parameters ofπ-type are10times larger than the equivalent parameters of energy storage components in the associated power grid，the risks of parametric resonance can be greatly reduced. Finally，the single-machine system with IPC15is set up，and the simulation results prove the correctness of the conclusions of the proposed parameter selection measures.
