Problems solved by technology

However, due to the incomplete and inaccurate information read in, the current distribution network automation system cannot read non-automated distribution network information, main network model and alarm information, and credit system information, etc.
In addition, the distribution network lacks reliable accident plans and auxiliary decision-making support, resulting in untimely and inaccurate handling of accidents by relevant personnel in the distribution network, and sometimes even requires manual investigation and location of faults, which seriously affects the power supply reliability of the distribution network

Embodiment Construction

[0027] Such as figure 1 As shown, the distribution network comprehensive intelligent alarm and processing method based on deployment integration includes the following steps:

[0028] S1, start

[0029] Start the distribution network comprehensive intelligent alarm system based on deployment integration.

[0030] S2. The distribution network reads the main network information

[0031] The distribution network EMS system reads the model information and measurement data of the main network EMS system, specifically including 10-20kV and above busbars, main transformers, switches and other physical and connection relationship information, which are used for online model reconstruction and power flow matching in step S3 ; In addition, the distribution network EMS system also needs to read the accident alarm information, relay protection action information, graphic files and accident briefing information of the main network EMS system for the integration of the alarm information i...

Abstract

The invention discloses a distribution network intelligent alarm and processing method based on integrated allocation. The method comprises the following steps: a distribution network reads main network information; models are merged and reconstructed to match flow; alarm information is integrated; an alarm model is constructed; safety assessment and intelligent analysis are conducted; comprehensive intelligent alarm is generated; and auxiliary recovery control decisions are automatically made. The method employs comprehensive safety state estimation technology, intelligent fault alarm technology, auxiliary decision making technology and the like, finds fault information of the distribution network automatically in real time, merges, analyzes and processes alarm information effectively, and instructs related persons of the distribution network to make correct decisions to ensure safe and reliable operation of the distribution network.

Description

technical field [0001] The invention relates to a distribution network comprehensive intelligent alarm and processing method based on deployment integration, and belongs to the technical field of distribution network automation. Background technique [0002] In the power system, once an accident occurs in the distribution network, it is required that the control personnel can quickly and accurately judge and screen out the real cause of the fault in a short period of time when a large amount of alarm information floods in, and make correct accident handling and fault recovery decisions based on the scope of the fault. , to restore the user's power supply as soon as possible. In the prior art, distribution network intelligent alarm and processing mainly depend on distribution network automation system (referred to as distribution network DMS system). However, due to the incomplete and inaccurate information read in, the current distribution network automation system cannot r...
