摘　　要：超高压输电线路是构建现代电力系统的重要部分,输电线路运行和故障时的物理分析,对研究继电保护原理、电力系统并列运行的安全性与稳定性尤为重要。静态模拟系统通过物理元件模拟电力系统状态变化时线路物理参数变化的情况,为研究分析线路故障特点和保障电力系统稳定性提供科学依据。采用计算仿真技术和基本物理元件相结合,研制静态模拟系统,该系统能够真实反映输电线路各种运行状态,特别是可以模拟输电线路可能发生的故障形式,并模拟故障时动作情况,能够对新研制的继电保护装置投用前进行试验性检验。As a significant carrier on the construction of modern power system, the physical analysis of extra high voltage （EHV） transmission line is important on the operations and the faults of transmission lines. Therefore, EHV transmission line is crucial to studies on relay protection, the safety and the stability of the parallel operation of power system. Through seeking for the variation of physical parameters amid the state change of power system stimulated by physical components, the static simulation system provides a scientific basis for studies on the characteristics of line faults and the stability of power system. On the basis of the combination of computer simulation technology and basic physical components, the system can truly reflect the various operations of the transmission lines. Especially, the system can simulate any possible fault of the transmission lines and guarantee the action situations during the course of fault simulation, providing an experimental test before the commissioning of newly developed protection.
