Problems solved by technology

Moreover, due to some uncertain factors in protection, circuit breaker misoperation, refusal and channel reasons, which are manifested as ambiguity, randomness and uncertainty, this makes the traditional evaluation based on probability theory and mathematical statistics theory Model is no longer applicable

Embodiment Construction

[0113] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0114] A real-time control device for power grid disasters based on intuitionistic fuzzy rough sets, such as figure 2 As shown, it includes data acquisition unit, monitoring unit, database unit, data processing unit and human-computer interaction unit.

[0115] The data collection and monitoring unit: used to collect meteorological data, power grid data, power grid equipment data and power grid dispatching data;

[0116] According to the collected data, the real-time status of the power grid and weather is monitored. When the power grid fails (such as short circuit, open circuit) or the weather is abnormal (such as extreme cold, extreme heat, severe drought, heavy rain, severe hail, strong typhoon, etc.) ) will send out an alarm message and record it, which includes weather data information, action information of relay protection devices and circuit ...

Abstract

The invention discloses a power grid disaster real-time regulating and control device and method based on an intuition fuzzy rough set. The method includes the steps that historical disaster data in a database unit are called; the collected historical disaster data are reduced through the method based on the intuition fuzzy rough set, and then disaster grade evaluation rules of a power grid are obtained; disaster data of the power grid are collected in real time, and the current disaster grade of the power grid is determined according to the formed historical disaster grade evaluation rules; the data which are evaluated in real time are updated to a historical database and used for addition and modification of a power grid disaster knowledge base; power grid disaster emergency responses are conducted, namely, corresponding emergency restoration measures are taken according to different disaster grades to regulate and control the power grid. According to the system and method, the situation that the data size used in the power grid disaster evaluation process has fuzziness, randomness, uncertainty, redundancy and other characteristics is taken into account, the defect that internal relations and potential relations of data attributes can not be acquired through a traditional probability theory and other method is successfully overcome by the utilization of the method based on the intuition fuzzy rough set, and evaluation accuracy is improved.

Description

technical field [0001] The invention belongs to the field of power grid disaster assessment and disaster level determination, and in particular relates to a power grid disaster real-time control device and method based on intuitionistic fuzzy rough sets. Background technique [0002] As a pillar industry of the national economy, the power system plays a very important role in supporting the sustainable development of the national economy and social progress. However, in recent years, there have been many large-scale blackouts caused by natural disasters at home and abroad, and the power system is facing severe challenges from various natural disasters. The paralysis of the power system has seriously affected the normal production and life of the society. One of the main reasons for such consequences is the failure to quickly and effectively evaluate the degree of damage to the power grid caused by natural disasters and identify the level of the power grid disaster, resulting...
