Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] see figure 1 As shown, a method for coordinating a power outage plan of the main distribution network includes the following steps:

[0020] Step S101, obtain basic data from the main network EMS system (Energy management system, energy management system), distribution network GIS system (geographic information system, geographic information system), metering automation system, and main and distribution network production systems, and then enter step S103 ; The basic data mainly includes: power grid topology information, quasi-real-time data, and business data.

[0021] Such as figure 2 As shown, in the embodiment of the present invention, the data of various business systems are integrated. As a better embodiment, the process of obtaining basic data from the main network EMS system, distribution network GI...

Abstract

The invention provides a method and a system for coordinating power-cut plans of a main network and a distribution network. The method includes the steps: acquiring basic data from a main network EMS (enhanced message service) system, a distribution network GIS (geographic information system), a metering automation system and a main network and distribution network production system; analyzing the influence of power-cut of main network equipment on distribution network equipment according to the basic data; and coordinating the power-cut plans of the main network and the distribution network according to analysis results. The basic data include power network topology information, quasi real-time data and business data. The business data are shared by integrating the basic data of business systems, and then the influence of power-cut of the main network equipment on the distribution network equipment is analyzed, so that the power-cut plans of the main network and the distribution network are automatically coordinated. According to the method and the system, manual intervention is omitted, communication costs of power network decision makers are reduced, and automatic coordination is higher in efficiency as compared with manual coordination.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method for coordinating a power outage plan of a main distribution network and a system for coordinating a power outage plan of a main distribution network. Background technique [0002] In the field of power system, the main network refers to the 110kV substation and above power grid, and the distribution network refers to the 10kV line. Due to the correlation between electrical and management, the blackout plan of the main distribution network needs to be considered as a whole, that is, the blackout plan of the main distribution network should be coordinated. [0003] The traditional method of coordinating the power outage plan of the main distribution network is mainly carried out manually. Power grid decision-makers determine annual and monthly power outage plans through meetings and negotiations. This method of conference negotiation has high communication costs and relative...
