WAMS based power grid disturbance recognition and system response assessment

Rational operation mode and efficient fault disposing is essential to power system security. Aimed to optimize power grid operation mode and improve scheduling real-time monitoring capabilities, this paper proposes a WAMS-based grid disturbance monitoring, analysis, evaluation, storage and off-line study framework. When a grid disturbance occurs, besides the principal features of the fault itself, the post-fault topology, power flow and security margin changes is also required. And it´s also important to evaluate the action response of generator governor system and other secondary equipment in power system. In addition, to achieve integrated management of power disturbances is helpful to off-line research and replay.
