Example Embodiment

[0053] EXAMPLIC The following steps (eg, figure 2 The desired electrical amount information and predetermined self-input model determines that the preset action logic of each fault event should be active or should not be moved; according to the acquired monitoring information and predetermined The current operating state of the self-investment model is determined by the auto-affected event is correct, the action failed or incorrect action; the preset action logic and judgment of the combined self-programs and the current action state of the judgment are determined to be properly active. , Malfunctional or refuse to obtain the final preparation from the final ready-to-auto operation information corresponding to each fault event.

[0054] The acquired electrical amount information collected in this embodiment includes a total mesh bus voltage and a zero-sequence voltage, a current value of the main power supply associated with each busbar, and the main power supply protection action...

Example Embodiment

[0077] Embodiment 2 Based on the example one, the intelligent alarm method of the power system preparation-based analysis provided in this embodiment also includes: displaying the final preparation self-exploising information corresponding to each fault event (eg Figure 5 The specifically includes:

[0078] 1 Visualization method realizes a fault briefing interface, and the fault briefing interface is a click to see the failure to see the failure.

[0079] 2 Prepare the operation information interface support information export and historical self-investment record query;

[0080] 3 Historical query interface support information exports and exports in time cycle, voltage grade query and export.

[0081] The present invention can automatically determine whether or not the active operation is properly operated according to the set action logic, which can provide a diagnostic reference to the monitor personnel, easy to resume power in time; by electrical amount analysis It is necessa...

Example Embodiment

[0082] Embodiment 3, corresponding to the example, this embodiment provides an intelligent alarm system based on power system, including: electrical amount analysis diagnostic module, monitoring information analysis diagnosis and synthesis module,

[0083] The electrical amount analysis diagnostic module is used to determine the preset action logic of each fault event according to the collected electrical amount information and the predetermined auto-output model;

[0084] The monitoring information analysis diagnosis is used to determine the current action state of each fault event in accordance with the acquired monitoring information and the predetermined auto-output model. The current operation state of each fault event is correct, the action failed or incorrect operation;

[0085] The integrated determination module is used to combine the preset action logic and judgment obtaining the current operation status of each fault event to obtain the final standby auto-action informa...

Abstract

The invention discloses an intelligent alarm method and system based on spare power automatic switching analysis of a power system. The method comprises the steps: determining preset action logic of spare power automatic switching under each fault event according to collected electrical quantity information and a predetermined spare power automatic switching model; according to the collected monitoring information and the predetermined spare power automatic switching model, judging a current action state of spare power automatic switching under each fault event; and obtaining final spare powerautomatic switching action information corresponding to each fault event by integrating the preset action logic of the spare power automatic switching and the current action state obtained by judgment. The method can be used to determine whether the spare power automatic switching is the spare power automatic switching maloperation caused by people or equipment damage or a correct action caused by an actual fault of a main power supply fault, does not need operation and maintenance personnel to go to a substation end for confirmation, can reduce dependence on the experience of the field personnel through judgment, and can greatly shorten the mode recovery time.

Description

technical field [0001] The invention relates to the technical field of electric power system power supply, in particular to an intelligent alarm method and system based on the analysis of electric power system backup and automatic switching. Background technique [0002] With the rapid development of my country's economy, higher requirements are put forward for the entire power industry, and reliable power supply has become the goal pursued by all power companies. For regions with a voltage level of 110kV and below where the power supply grid is relatively weak, a large number of backup power automatic input devices are equipped. Because the operation of the regional power grid will be changed after the backup and automatic switching operation, it will often cause the main transformer or power supply line. Overload will also bring difficulties to operation and maintenance. Therefore, high requirements are put forward for the reliable operation of the backup automatic switchi...
