铁磁谐振过电压对电网的安全运行构成了严重威胁,如何对其进行监测和有效抑制,这对保障电网安全运行具有重要意义。分析了电网中铁磁谐振过电压产生的原理,设计了一种基于DSP新型控制系统,并对系统的硬件和软件进行了设计。通过仿真与实验证明,该新型控制系统动作可靠,抑制效果好,具有良好的市场应用价值。

Ferro-resonance over-voltage is a serious threat to the safe operation of power grid. How to moni- tor and effectively control it is of great significance to protect the safe operation of power grid. This paper analyzes the theory of the power system over-voltage generated by ferromagnetic resonance, and designs a new type of control system based on DSP. And its hardware and software of this system is designed in this paper. The simulation and experiment show that the new control system has the reliability, a good inhibi- tory effect, a good market value.
