A method for remote sharing of power grid fault characteristic data among dispatching control systems

Abstract

The invention provides a method for power grid fault characteristic data remote sharing among scheduling control systems and belongs to the technical field of intelligent analysis and control of electric power systems. The method, based on the wide area service bus technology, proposes the interactive mode and interactive content of power grid fault characteristic data among scheduling control systems; and scheduling control operating personnel can directly retrieve power grid fault characteristic data such as split-phase switch position change, bay accident integration and protection action signals of equipment faults of other scheduling control systems via a local scheduling control system, remote sharing of power grid fault characteristic data is achieved and the power grid equipment fault online sensing ability of scheduling control operating personnel is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system intelligent analysis and control, in particular to a method for remotely sharing power grid fault characteristic data among dispatching control systems. Background technique [0002] Power grid fault characteristic data is an important basis for dispatching operators to deal with faults. Due to the division of dispatching and monitoring services, the dispatching right and monitoring right of the same equipment belong to different dispatching agencies (for example, the dispatching right of 500kV equipment is in the regional power grid control center, monitoring The power is in the provincial power grid control center, the dispatching power of 220kV equipment is in the provincial power grid control center, and the monitoring power is in the regional power grid control center), the equipment fault characteristic data is generally only collected in the dispatching control system with moni...

[0002] Power grid fault characteristic data is an important basis for dispatching operators to deal with faults. Due to the division of dispatching and monitoring services, the dispatching right and monitoring right of the same equipment belong to different dispatching agencies (for example, the dispatching right of 500kV equipment is in the regional power grid control center, monitoring The power is in the provincial power grid control center, the dispatching power of 220kV equipment is in the provincial power grid control center, and the monitoring power is in the regional power grid control center), the equipment fault characteristic data is generally only collected in the dispatching control system with monitoring power, and the dispatching power with dispatching power The control system does not collect or only collects part of the data. In the case of power grid equipment failure, it is difficult for dispatching and operating personnel to quickly grasp the details of equipment failure, which affects the efficiency and timeliness of dispatching fault handling

[0003] At present, although the smart grid dispatching control system has the function of real-time push and remote sharing of power grid fault alarm information across dispatching control systems, the fault information shared remotely is limited to fault time, faulty equipment, fault phase, coincidence, and fault distance measurement. There is no corresponding remote sharing mechanism for the phase-splitting switch action signal and protection action signal that are the focus of dispatching and troubleshooting.
