Cooperative fault handling method for provincial and regional dispatching of power grid faults

Abstract

The invention provides a collaborative fault handling method for provincial and regional dispatching of power grid faults, which comprises the following steps: acquiring an online fault diagnosis information table, and extracting real-time fault information in the online fault diagnosis information table; matching the real-time fault information with a prestored provincial and regional co-processing plan; if the provincial and regional co-processing plan is matched, judging whether a co-processing condition is met or not, and if the co-processing condition is met, starting an online analysis application in provincial dispatching, and obtaining real-time processing information when the provincial and regional co-processing plan is executed through the online analysis application; and the provincial dispatcher determines a fault handling range according to the real-time handling information, the fault handling range is synchronously uploaded to the local dispatcher, and the provincial dispatcher and the local dispatcher execute a provincial and local cooperative handling plan in the fault handling range. According to the invention, real-time interaction of fault information can be realized through the provincial and regional wide-area service bus, the provincial and regional power grid fault synchronous sensing capability is improved, the provincial and regional fault co-processing efficiency is improved, and rapid recovery of power grid faults is supported.

Description

technical field [0001] The invention belongs to the technical field of intelligent analysis and control of power systems, and in particular relates to a collaborative fault handling method for power grid fault and land-saving scheduling. Background technique [0002] With the rapid development of the AC / DC hybrid power grid, the overall operation of the power grid presents an integrated feature, the impact of faults on the system is significantly globalized, and the difficulty of fault perception is significantly increased. Power grid fluctuations in local areas, equipment failures, and even normal equipment operations are all possible. Trigger a chain reaction, causing system disturbance across the entire network. Power companies usually deploy provincial dispatching and local dispatching, which are used for power dispatching within the province and prefecture-level cities / counties respectively. [0003] In the face of power grid faults, based on local alarms and isolated ...

AI Technical Summary

Problems solved by technology

[0003] In the face of power grid faults, based on local alarms and isolated analysis methods, there is a lack of sharing of fault information and analysis results between the provincial dispatching and local dispatching, which affects the effect of provincial and local coordinated fault dispatching, especially in complex power grids under extreme conditions. Faults cause major changes in the operation structure of the power grid, and the difficulty of fault handling is significantly increased. It is difficult for a single dispatching organization to perceive the operating status of the entire network and cannot accurately handle faults.
