Modeling FACTS for power flow purposes: A common framework [PDF]
This paper intends to give a common modeling framework for power flow calculations in power systems with embedded FACTS devices. The proposed method uses the node incidence matrix (Γ) to avoid the problems derived from the widely used admittance matrix.

统一潮流控制器(UPFC)是最新一代柔性交流输电系统装置,综合了FACTS元件的多种灵活控制手段。受限于电力电子设备绝缘能力,UPFC故障穿越能力有限。文中在介绍UPFC串联侧故障快速隔离技术的基础上,提出了UPFC配合交流保护重启策略,发生影响UPFC运行的故障时,利用特征量进行故障区域和类型判别,判别为交流电网异常时,进一步根据故障特性,并检测电网运行状态和UPFC运行能力,执行UPFC故障穿越或短时闭锁后自动重启的策略。接着以500 kV苏南UPFC工程为例,介绍了该策略的具体实现方案 ...
