中文摘要	谐振型故障电流限制器是解决超高压电网短路电流超标方案之一。相对于其他限流器,谐振型能适应电网的各种复杂操作,在工程上具有可实现性。从谐振型主电路回路入手,建立阻抗模型,分析谐振型阻抗参数的影响因素,比较了谐振型与补偿型阻抗模型的异同。从限流角度,提出了抑制因子和谐振因子2个影响阻抗参数;在考虑限流器故障态模式下,从系统角度,提出了负补偿度概念,探讨了负补偿度与装置容量和输送功率的关系。在参数优化设计理论分析上,通过仿真计算,给出了参数优化范围。仿真结果表明,阻尼回路电气强度大大降低,限流器限流效果明显。; The resonance fault current limiter (RFCL) is a practical way to solve the problem of bulk fault current on the EHV. RFCL has the advantage to be able to adapt to complex operations of power grids. The resistance model is built from the main circuit of RFCL in the paper and the parameters affecting the resistance are analyzed. Furthermore, the resonance model is compared with compensated model. From the view of limited current, two parameters of restrain coefficient and resonance coefficient affect the value of the resistance. From the view of system, the negative compensation degree limits the device capability and delivering power under the RFCL fault mode. A large amount of simulation experiments are carried out. The parameters are successfully optimized and electrical strength of the damping circuit is decreased significantly. RFCL has good response to the short circuit current.; 国家电网公司科技项目(SGKJ[2004]03-35)~~
