Multi-Timescale Cascading Outage Model Considering Generator Excitation Protection and OLTC
摘要
Abstract
Voltage and reactive power characteristics play an important role in cascading outages and blackouts in power systems. In this paper, a multi-timescale cascading outage model considering on-load tap changer (OLTC) and generator excitation protection was proposed. This model proposed a multi-timescale cascading outage simulation framework, in which clear expression of time in cascading outage simulation was realized, thus overcame limitation of traditional models. Modeling of generator excitation protection and OLTC simulation were introduced in this model. The IEEE-30 system case studies analyzed mechanisms of generator excitation protection and OLTC, and their influence on cascading outage risk and process. Moreover, phrasal characteristics of cascading outages are analyzed using this model.关键词
