Embodiment Construction

[0094] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0095] An auxiliary decision-making method for online power system recovery, which can automatically generate the black-start power supply to the activated power supply by selecting a suitable black-start power supply according to the actual operation status of the power outage accident in the interconnected power system or the artificially set simulated power outage environment The path with the best comprehensive performance is used to start the entire power grid through this path, thereby realizing the restoration of the entire power system.

[0096] The terms are described below:

[0097] 1) Black start: After the entire system is out of service due to a failure, it does not rely on the help of other networks. Through the start-up of units with self-starting capabilities in the system, the units without self-starting...

Abstract

The invention relates to an auxiliary decision-making method for on-line power system restoration. The auxiliary decision-making method comprises the following steps: reading electric grid initial data; setting imitation environment; choosing a black-start power source; generating a black-start restoration route; restoring an electric grid based on an optimum restoration route; and managing computing results. The system and the method fully utilize real-time data such as remote signaling, remote measuring and electric grid topological information in a dispatching automation system and quickly generate the power system restoration route and a restoration scheme, and therefore when power system serious power cut accidents happen, the system and the method can assist dispatching operational workers to carry out system restoration operation, shorten time of power cut to the maximum and reduce loss caused by the power cut. In addition, the system and the method have an important in national economic stability and also reduce working intensity and working pressure of the dispatching workers to the maximum.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an auxiliary decision-making method for online power system restoration. Background technique [0002] In recent years, with more and more new technologies and new equipment being put into the power system, while improving the operation capability and efficiency of the power system, it also brings great challenges to the safety and stability of the system. Individual problems in local power grids can easily expand the scope of influence if they are not handled properly, and even cause large-scale power outages. How to quickly restore power supply after a major power outage in the power grid is of great significance. [0003] At present, the common practice of domestic and foreign power system black start is that experienced dispatching and operation experts study and formulate a feasible black start plan in advance according to the specific conditions of the system, or calculate a f...
