摘　　要：随着配电网中电缆线路的大量使用,系统出现基波电流谐振的可能性大大增加,对系统的安全运行和供电可靠性造成不利影响。结合某变电站异常运行状态实例,在理论分析和MATLAB语言数值计算的基础上,指出由于电力电缆的大量使用导致了该系统参数配合不当,从而诱发了基波电流谐振,并提出装设静态补偿器(SVC)以防止和处理该类谐振。应用MATLAB中Simulink及其电力系统仿真工具箱(SimPowerSystems)建立了相应的动态仿真模型进行详尽的仿真研究。仿真分析结果表明,该方法是行之有效的。Along with the extensive use of power cable lines in power distribution system, the probability of fundamental frequency resonance has greatly increased. It may endanger the security operation and power supply reliability of the power system. On the basis of theoretical analysis and numerical calculations using MATLAB language combined with a real instance, it is indicated that the improper electrical parameter coordination caused by the abundance of power cable lines result in fundamental frequency current resonance, in addition, the countermeasures based on SVC to solve the problem are put forward. Further more, digital simulations have been carried out in detail based on the dynamic simulation model developed by the application of MATLAB/Simulink and its power system simulation software. Simulation results proves the effectiveness and practicability of the scheme presented.
