【摘要】 在分析了自适应相补偿电压突变量方向元件动作特性的基础上,针对该元件进行了正、反方向不同故障点,不同故障类型的仿真分析。利用ATP/EMTP建立了振荡典型参数可控的振荡仿真模型,并对自适应相补偿电压突变量方向判别元件在纯振荡中和振荡中再发生故障的情况分别进行了仿真分析,结果表明该方向元件在各种故障情况下均能正确动作,在纯振荡中不会误动。更多还原

【Abstract】 Based on analysis of characteristic of self-adaptive fault directional discriminating criteria based on superimposed component of compensation voltage,simulation and analysis of characteristic in different kinds of faults on different direction is put forward.A controllable oscillation simulation model is established with ATP-EMTP for the purpose of simulating and analyzing the characteristic of directional discriminating in oscillation with fault and without fault.The result of simulation and analysis indicates that the direction element could act selectively and rightly in any kinds of faults and oscillation with and without fault.更多还原
