【摘要】 基于多端口网络理论,提出采用相补偿法进行含固态限流器的电力系统断相加短路故障计算。该方法可以方便地模拟断相加短路故障中固态限流器以及短路点接触电阻的影响,避免了序坐标下复杂的序网连接。算例分析验证了该方法的有效性。更多还原

【Abstract】 Based on the theory of multi-port network, it isput forward that the compound fault, which consists ofdisconnection fault and short circuit fault, of power systemwith solid-state fault current limiters can be calculated by phasedomain compensation method. Using phase domaincompensa-tion method the influence of solid-state fault currentlimiters and that of the contact resistance at the position, wherethe short circuit fault occurs, during the compound fault can beeasily simulated, and the complex connection of sequentialnetworks in the fault calculation can be avoided. The results ofcalculation examples show that the proposed method iseffective for compound fault.更多还原
