Embodiment Construction

[0027] Such as figure 1 As shown, the grid state estimation result analysis and alarm method of the present invention includes the following steps:

[0028] Step 1, set the FTP address for storing the grid state estimation result file, and the corresponding relationship table between the grid state estimation result file and the storage time;

[0029] Step 2, set the query time range of the power grid state estimation result file, the threshold judgment condition and the alarm type configuration information;

[0030] Step 3, according to the FTP address of the power grid state estimation result file, check whether there is an update of the power grid state estimation result file, if there is no update, go to step 4, if there is an update, go to step 5;

[0031] Step 4, store the current power grid state estimation result file to the FTP address set in step 1, and update the corresponding relationship table;

[0032] Step 5: Search in the corresponding relationship table acco...

Abstract

The invention provides a power grid state estimation result analysis and alarm method and device. The power grid state estimation result analysis and alarm method comprises the steps of setting initializing, query condition setting, file updating, file query, and query judgment and warning. The power grid state estimation result analysis and alarm device comprises an initializing module, a condition setting module, an query updating module, a file updating module, a query judging module and an alarm module. By the adoption of the power grid state estimation result analysis and alarm method and device, real-time active query analysis can be achieved, an alarm can be given in real time, manual attendance is not needed at all, and labor is saved.

Description

technical field [0001] The invention relates to a method and a device for monitoring the state of a power grid, in particular to a method and a device for analyzing and alarming the state estimation results of a power grid. Background technique [0002] Power system state estimation is one of the core functions of the power system energy management system (EMS). Its function is to estimate the current operating state of the power system based on various measurement information of the power system. Due to various reasons (such as data distortion caused by channel interference, damage to transformers or measuring equipment, untimely system maintenance leading to reverse direction, etc.), some telemetry results of the power system may be far from their true values, and telemetry results may also be wrong. These measurement data are called bad data or bad data, which will lead to errors in topology analysis, which will seriously affect the state estimation results. The existing...
