A method for intelligent transformation of conventional substations

Abstract

The invention belongs to the technical field of a power system, in particular to an intelligent transformation method of a conventional substation. The intelligent transformation method comprises the following steps of additionally arranging a monitoring system based on a panorama data integrated information platform in a traditional station control layer; unifiedly applying IEC61850 stipulation by a full-station communication protocol; substituting a traditional main transformer protection device in a separation layer by a post-main integrated intelligent protection device; applying a multi-functional measurement and control device by a measurement and control device; applying a mode of a traditional switch and an intelligent terminal to complete intelligent transformation by a switching device; and additionally arranging a one-time device on-line monitoring system in a process layer. By proceeding two aspects of building of a new substation and intelligent transformation on the conventional substation, a three-layer and two-network standard structure of the intelligent substation is taken as a target, and intelligent transformation is carried out on the process layer, the separation layer and a device and the function of the station control layer. By the transformation method, the operation and maintenance cost of the substation can be reduced, resource configuration is optimized, the operating index is improved, and the transformation method is profound significance to the power system.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a method for intelligent transformation of conventional substations. Background technique [0002] With the development of the economy, the demand for power is getting stronger and stronger, the scale of the power grid is constantly expanding, the structure of the power grid is becoming more and more complex, and the requirements for power supply reliability are getting higher and higher. Today, the principle and technology of microcomputer protection in my country are quite mature. The main causes of accidents in conventional substations are misoperation caused by aging and grounding cables, failures caused by deterioration and inconsistency of CT characteristics, and error-prone seasonal switching of pressure plates. In the past few years, the quality of domestic intelligent primary equipment products has improved very rapidly. From the recent feedback of some...

Problems solved by technology

[0004] 1. Smart substations can achieve a good low-carbon environmental protection effect. In smart substations, traditional cable connections are no longer used in engineering, replaced by optical fiber cables, which are widely used in various electronic devices. Electronic components with low consumption. In addition, the traditional oil-filled transformer has not escaped the fate of being eliminated, and the electronic transformer will replace it

[0005] 2. The working characteristics and responsibilities of the smart substation make it necessary to have good interaction

The network 103 protocol of conventional substations is greatly different from the understanding of each equipment manufacturer, and the information interaction ability between equipment is poor, which is not conducive to information sharing
