Embodiment 1

[0024] see figure 1 As shown, it is a schematic flowchart of an embodiment of the method for assessing the main network N-1 risk based on the power grid outage plan of the present invention. Such as figure 1 As shown, the main network N-1 risk assessment method based on the power grid outage plan in this embodiment includes the following steps:

[0025] Step S101: Obtain business data, power grid topology, and equipment ledger information. The business data includes power outage plan data, and enter step S102, where the power grid topology includes main network equipment topology information and distribution network equipment topology information, and equipment ledger information. It is divided into main network ledger information and distribution network ledger information. Outage plan data can be obtained from the main network production system, main network device topology information is generally obtained from the main network EMS system, and distribution network device t...

Embodiment 2

[0036] According to the method for assessing the main network N-1 risk based on the power grid outage plan of the present invention, the present invention also provides a main network N-1 risk assessment system based on the power grid outage plan. The specific embodiment of the main network N-1 risk assessment system based on the power grid outage plan will be described in detail below.

[0037] Such as figure 2 As shown, it is a schematic structural diagram of an embodiment of the main network N-1 risk assessment system based on the power grid outage plan of the present invention, which includes:

Abstract

The invention provides a power network power-cut scheme based major network N-1 risk assessment method and a system. The method includes steps that business data, power network topologies and device standing book messages are acquired, wherein the business data contain power-cut scheme data; new power network topologies are generated according to the power network topologies and the power-cut scheme data; supposition fault sets are established through the device standing book messages and the new power network topologies, and each element in the supposition fault sets corresponds to power network devices which meet pre-suppositional conditions in the device standing book messages respectively; and the elements in the supposition fault sets are traversed, the devices corresponding to the elements in the supposition fault sets are regarded as supposition fault devices, and supposition fault analysis is performed according to the new power network topologies to obtain analysis results. By means of the power network power-cut scheme based major network N-1 risk assessment method and the system, a large amount of labor is saved, simultaneously, the analysis results are accurate, and efficiencies for examining and approving a power-cut scheme are greatly improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and system for assessing the main network N-1 risk based on the power grid outage plan. Background technique [0002] With the continuous development of power business, various power business systems are also constantly improving. The existing more mature power business systems include main network EMS system (energy management system), distribution network GIS system, main network asset system, main network Production systems, metering automation systems, etc., these power business systems store various data of power grid operation. With the development of power business, application business integration, integrated platform and unified portal have become a trend. How to make full use of the massive data stored in these power business systems to obtain better application effects has brought about changes in marketing business management. In order to achieve sig...
