System and method for realizing multidirectional issuing of relay protection operation information in smart grid

Abstract

The invention relates to a system for realizing multidirectional issuing of relay protection operation information in a smart grid. The system comprises a universal Internet area, a mobile accessing management area, a power office affair handling management area and a power production large area, wherein the universal Internet area, the mobile accessing management area, the power office affair handling management area and the power production large area are successively connected. The power production large area comprises the components of a transformer substation terminal station which is used for acquiring and uploading information of relay protection equipment in real time; and a scheduling end main station which is connected with the transformer substation terminal station through a power data network and is furthermore connected with the power office affair handling management area for performing analysis, processing and multidirectional issuing on the received data of each substation. The system and the method for realizing multidirectional issuing of the relay protection operation information the smart grid have advantages of greatly improving grid scheduling operation management efficiency, reducing workload and technical difficulty of operation personnel in professional maintenance, ensuring safe and stable operation of the transformer substation, realizing an advantages in efficiency, practicability and economic benefit, and laying the basis for high-efficiency operation of relay protection.

Description

technical field [0001] The present invention relates to the field of smart grids, in particular to the technical field of relay protection operation and maintenance management in smart grids, and specifically refers to a system and method for realizing multi-dimensional release of relay protection operation and maintenance information in smart grids. Background technique [0002] With the rapid advancement of the smart grid construction of the State Grid Corporation of China, the degree of intelligence of the relay protection equipment in the substation is getting higher and higher, and the corresponding installation, commissioning and operation and maintenance methods of the relay protection equipment have also undergone major changes. The relay protection operation and maintenance management system mainly collects the panoramic data of the relay protection equipment and its circuits in the substation remotely, and uses big data, intelligent diagnosis and other technologies ...

AI Technical Summary

Problems solved by technology

This method mainly has problems such as high manual participation, low efficiency in finding and handling abnormalities, difficulty for relevant professionals to grasp the operation status of equipment in time, high cost investment, and low economic benefits.

There is a certain degree of contingency and randomness in the occurrence of abnormalities in the operation of the equipment. Human labor needs to be on duty around the clock. After discovering the problem, the relevant personnel will be notified one by one. The handling of abnormalities involves the cooperation of multi-professional operation and maintenance personnel, and it is easy to miss the situation of notifying relevant professionals

If workstations are set up for each major, the number of on-duty personnel will increase significantly, and the operation and maintenance costs will increase

With the increasing scale, the workload of secondary equipment operation and maintenance has increased sharply, and this operation mode can no longer meet the requirements of the rapid development of smart grid

[0006] At the same time, in the era of universal application of mobile communication, various abnormalities and fault information that appear during the operation of relay protection equipment in substations cannot be quickly pushed to different professional operation and maintenance personnel in a universal and convenient way, resulting in accidents and accidents. It is difficult to achieve timely and effective cooperation between various departments during the processing process, and the transportation inspection business does not yet support paperless operations. These problems need to be resolved urgently
