Fault trip-out rapid studying and judging method for massive power grid signals

Abstract

The invention provides a fault tripping rapid studying and judging method for massive power grid signals, and the method comprises the steps: building an equipment signal monitoring engine through a finite state machine in advance, and capturing a to-be-monitored signal of equipment in the massive power grid signals; obtaining D5000 system alarm information, obtaining measurement information of telemetering and telesignalling, and obtaining topological information of a PMS equipment management system interface; and the equipment signal monitoring engine is adopted to monitor equipment signals, and in combination with the D5000 system alarm information, the measurement information of the telemetering and telesignaling and the topological information of the PMS equipment management system interface, three types of accidents of line faults, main transformer faults and switch tripping are identified, and the power failure range is determined. According to the method, the fault tripping risk can be quickly identified, the power failure range is displayed, and the scheduling response time is shortened.

Description

technical field [0001] The invention relates to the technical field of power system detection, in particular to a method for rapid research and judgment of fault tripping oriented to massive power grid signals. Background technique [0002] With the rapid development of the national economy and the increasing demand for power supply, the power sales have repeatedly hit new highs. In order to meet the needs of national economic development, the power grid construction has been continuously increased, and the number of substations and lines has also continued to increase. The number has increased dramatically, and it is difficult to quickly identify faults from the vast number of signals. [0003] In the prior art, when abnormal information occurs in the power grid, the dispatcher can only view it through the scada alarm window. It is very likely that the dispatcher fails to view the alarm window in time at a certain time, or the trip fault is not detected in time due to the e...

Problems solved by technology

[0002] With the rapid development of the country's economy, the demand for power supply is increasing, and the electricity sales have repeatedly hit new highs. In order to meet the needs of the country's economic development, the construction of the power grid has been continuously intensified, and the number of substations and lines has also continued to increase. The number has increased sharply, and it is difficult to quickly identify faults from a large number of signals

[0003] In the prior art, when there is abnormal information in the power grid, the dispatcher can only view it through the scada warning window, and it is very likely that the dispatcher fails to check the warning window in time at a certain time, or fails to detect the trip fault in time due to the excessive signal volume of the warning window situation, which will prevent the fault from being dealt with in a timely manner
