Power grid wide area real time monitoring system and control method

Abstract

The invention discloses a power grid wide area real time monitoring system and a control method, and belongs to the power grid monitoring technical field; the power grid wide area real time monitoringsystem comprises a plurality of synchronization phasor measurement systems, a central monitoring control system, a Beidou satellite positioning system and a plurality of lightning arresters; the synchronization phasor measurement system is used for obtaining the power grid real time state information and sending the information to the central monitoring control system through the Ethernet; the central monitoring control system is used for analyzing and processing the power grid real time state information and carrying out scheduling early warning control; the Beidou satellite positioning system is used for emitting Beidou satellite positioning information to the synchronization phasor acquisition system, wherein the Beidou satellite positioning information comprises positioning information and authorization time information; the lightning arresters are used for providing the lightning arrester state information for the synchronization phasor acquisition system. The power grid wide area real time monitoring system and the control method can realize power grid wide area real time monitoring, thus alleviating the power system fault maintenance cost, accelerating the repairing speed,and fully intelligently scheduling and managing the power grid system.

Description

technical field [0001] The invention relates to a wide-area real-time monitoring system and a control method for a power grid, belonging to the technical field of power grid monitoring. Background technique [0002] Since the reform and opening up, my country's gross national product has continued to increase, people's social life has become more and more abundant, and the overall comprehensive national strength has also continued to increase. One of the very important factors for all these achievements is that our country is moving towards automation, informatization and intelligence at a high speed. Behind these major changes is that the production and life of the whole society are increasingly dependent on electricity and power grids. From ordinary home lighting, air conditioning, TV, computer and network equipment, to industrial production lines, power, office space, to large equipment, IT support systems, financial payment systems, without exception, all strongly depen...

Problems solved by technology

[0003] However, it is always inevitable that there will be problems of one kind or another in the power system. For example, at some special moments - high temperature and scorching summer, the power grid system of the whole country will be under tremendous pressure

In addition, some unforeseen natural factors and disasters, such as blizzards, mudslides, earthquakes, floods, lightning strikes, etc., may also have an uncertain impact on the power grid system at any time. Any possible impact will have a negative impact on social production and people's It will have a huge impact on all areas of life and society, and even cause huge economic losses
