Embodiment Construction

[0031] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0032] The power grid equipment of the present invention is divided into two types of load and other equipment. The so-called load lines refer to those 10kV (and a small amount of 35kV) lines that directly carry loads. First, the load model is expanded. In order to calculate and count outage users, it is necessary to expand the model and add four attributes: "number of users", "number of important users", "important users" and "level of important users".

[0033] A load may correspond to multiple "important users" (similarly, there may be multiple corresponding "important user levels"), and 5 important users and user levels may be reserved by default. The user level ma...

Abstract

The invention discloses a topology analysis-based regional power grid fault loss consequence calculation method. A "load" of a regional power grid intelligent dispatching main station system is subjected to model expansion, and attributes including "a power failure affected user number", "a power failure affected important user number", "important users" and "important user levels" are added; the regional power grid intelligent dispatching main station system stores data sections and divides power grid fault devices into loads and other devices, and the system can accurately calculate fault loss loads based on topology analysis and load models regardless of faults, judge power failure devices, analyze a power failure range and perform statistics on the power failure affected users; and by adopting the method, a fault loss load calculation result is more accurate, and relatively rich power failure affected user information and a power failure range analysis function are provided, so that the technical requirements of an intelligent power grid are better met, and the method has very high engineering practicality and very wide application prospects.

Description

technical field [0001] The invention relates to the field of electric power system automation, in particular to a method for calculating the consequences of faults in regional power grids based on topology analysis. Background technique [0002] Power grid failure will cause losses, and the consequences of grid failure losses are highly valued by grid operators. The loss consequences of grid failure include loss of load, outage equipment and outage users. in: [0003] (1) Fault loss load = fault removal load + low voltage tripping loss load; [0004] (2) Power outage equipment includes faulty equipment and other equipment that is out of power due to this failure, and finding out outage equipment is to analyze the scope of power outage; [0005] (3) Power outage users include the number of power outage users, the number of power outage important users, the level of power outage users (the most serious level among all power outage users) and the power outage important users...
