Embodiment Construction

[0018] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] The invention is suitable for implementing and deploying a smart grid dispatching technical support system and deploying a WAMS application in a power grid. The power system large-disturbance fault location visualization system is a sub-module under the application of WAMS. It is based on the smart grid dispatching technology support system platform. Through the large-disturbance fault location system, the fault location information in the power grid can be quickly grasped, which is convenient for quick analysis and release of dispatching. Instructions to eliminate grid faults, thereby maintaining or improving the stable operation of the grid;

[0020] The relationship between the wide area measurement system WAMS, the background detection service module and the visual human-machine interface module is shown in the attached f...

Abstract

The invention discloses an implementation method of a large disturbance fault approximate positioning visualization system of a power system, which comprises a large disturbance fault detection method based on a support system platform of an intelligent power grid scheduling technology and a software architecture. A large disturbance fault positioning and rendering visualization man-machine interface design technology, a reading and writing access technology of a domestic commercial database and a data access technology of a WAMS (wide area measurement system) time sequence real-time library are adopted. The technical scheme disclosed by the invention is used for solving the problem of performing approximate positioning on large disturbance faults in uncertain fault types in the support system of the intelligent power grid scheduling technology and providing an auxiliary tool and a convenient means for enabling scheduling operation staff of a power grid to fast position a fault source in the power grid.

Description

technical field [0001] The invention belongs to the field of dynamic monitoring of electric power systems, and in particular relates to an approximate positioning technology and a visualization system for large disturbance faults in electric power systems. Background technique [0002] As the scale of power grid construction becomes larger and larger, more and more types of faults occur during the operation of the power grid. Some fault types can be identified, such as short circuit, low-frequency oscillation, unit tripping, etc.; There are some situations where there are obvious large disturbances and it is not clear what type of fault it is. At this time, it will bring certain obstacles to the power grid operation dispatcher to issue dispatching instructions correctly and maintain the stable operation of the power grid. Therefore, it is urgent to study a large disturbance fault approximate location technology, and a visual fault location system that can quickly locate and ...
