| 摘 要： | 换相过电压在可控硅整流系统中广泛存在，介绍了一种通过建模仿真，研究换相过电压及其抑制措施的新方法。根据三峡电站励磁系统参数，建立了励磁系统及其过电压抑制措施仿真模型；模型计算得到的过电压波形与现场实测结果一致性好。仿真分析了不同参数下整流式、三角形、星形3种换相过电压抑制方案，仿真结果与现场实测结果基本一致，对工程实际有指导意义。 |

| Abstract: | Periodic phase conversion overvoltage is inevitable in silicon controlled rectifier excitation system.RC protection device can be used to reduce the amplitude and gradient of overvoltage,while it is difficult to choose proper parameters.This paper introduced a new method to solve this problem.A simulation model of excitation system based on parameters of Three Gorge Power Plant was constructed.Three kinds of phase conversion overvoltage restrict devices were studied.The simulation result is quite in agreement with the local test and the method can be helpful for local engineers to choose a proper way and proper parameters to suppress the phase conversion overvoltage. |
