Embodiment 1

[0051] figure 1 A schematic flowchart of a power grid fault level publishing method provided by the first embodiment of the present invention is shown.

[0052] The method is applied to an electricity dispatching system, and the method flow shown in this embodiment includes the following steps:

[0053] Step S110, acquiring fault information of the electricity dispatching system.

[0054]Monitor the main network and distribution network faults of the electricity dispatching system. In this embodiment, the power dispatching system is connected with the EMS system and the DMS system through data fusion and model splicing technology, and the main network failure of the power dispatching system is monitored through the EMS (energy management system), and the power dispatching system is monitored through the DMS (power distribution system). management system) monitors the faults of the distribution network of the electricity dispatching system. In some other embodiments, other s...

Embodiment 2

[0101] figure 2 It shows a schematic flowchart of a power grid fault level publishing method provided by the second embodiment of the present invention.

[0102] The method is applied to an electricity dispatching system, and the method flow shown in this embodiment includes the following steps:

[0103] Step S210, monitoring the faults of the main network and the distribution network of the electricity dispatching system.

[0104] Step S220, judging whether the splicing of the main network and the distribution network is successful.

[0105] Since the topology of the main network of the power dispatching system and the topology of the distribution network are not directly related, the topology of the main network and the topology of the distribution network are mutually blocked. Therefore, the main network and the distribution network of the power dispatching system are first Splicing, to obtain the fault information of the main network and distribution network of the enti...

Abstract

The invention discloses a method for releasing a fault level of a power network, which is applied to a power dispatching system. The method comprises the following steps: obtaining fault information of the power dispatching system; Calculating data information of the power network fault according to the fault information; Evaluating a fault grade of the power network fault according to the data information of the power network fault and a predetermined rating standard; Setting a fault receiving range of a corresponding receiving object according to the fault level; According to the receiving object range, the fault level and the data information are sent to the corresponding receiving object according to a predetermined format to start the emergency plan of the corresponding level. The invention analyzes the power network fault according to the power network fault information and quickly prejudges the power network fault grade according to the rating standard, and sends the power network fault grade information to the corresponding receiving object, so as to provide technical support for the rapid response of the power network fault.

Description

technical field [0001] The invention relates to the technical field of power grid automation, in particular, to a method for issuing power grid fault levels. Background technique [0002] Laws and regulations such as the New Safety Production Law have put forward higher management requirements for accidents (events) that affect the normal power supply of users. When an abnormality occurs in the power grid, the dispatcher has to screen, analyze, and judge a large amount of alarm information, and also perform corresponding fault handling and operations. At the same time, it is necessary to carry out the collection and statistics of abnormal impact information, and conduct a preliminary "qualification" of the accident (incident) level, so as to provide a reference for the emergency command organization to start the corresponding level of emergency response or plan. Due to the lack of sufficient management and technical support, the "qualification" is often inaccurate and the r...
