Transient stability control system based on mapping cloud and online pre decision

Abstract

In order to reasonably describe the uncertainty of output of instruments and actuators, a concept of transient stability control based on online pre-decision of mapping cloud is proposed. This paper describes an online pre-decision transient stability control system developed by Electric Power Automation Research Institute, which integrates quantitative analysis technology of motion stability of nonautonomous nonlinear multi-rigid-body system, object-oriented distributed parallel processing platform and regional stability control device. The system online tracks the system working conditions using the stability margin index of the controlled power system provided by EEAC, and quickly searches for the control strategy that corresponds to a given fault set, satisfies a certain system stability margin value, and has the least control cost, so as to correct The development and change of the power grid and the change of operation mode have strong adaptive ability. The system is an organic combination of transient stability quantitative analysis technology EEAC and mature regional stability control device FWK, and is a new product of domestic safety and stability control technology.
