Achieving method of transformer substation functional redundancy

Abstract

The invention discloses an achieving method of transformer substation functional redundancy. A designing method through which double side operation and main standby states are judged via hard-wired interaction redundancy device state information is used, according to the classification principle of transformer substation operation information, station level equipment carries out data selecting based on the main standby states and the attribute of the transformer substation information class, and redundancy monitoring on a transformer substation monitoring system is achieved. In a control direction, through a station level central control server, the uniqueness of transformer substation control is guaranteed, meanwhile, control functional redundancy is achieved, and the reliability of transformer substation system operation is effectively improved.

Description

technical field [0001] The invention relates to the field of substation monitoring, in particular to a method for realizing redundancy of substation measurement and control functions. Background technique [0002] In the substation design, the measurement and control device is mainly used to measure and control the data and signals of the substation bay layer, so as to realize the monitoring of the whole substation. With the implementation of the integrated project of protection, measurement and control, according to the principle of dual configuration of protection devices, the redundancy of measurement and control functions has resulted. This results in all data in the system being duplicated. Operators need a certain amount of time to find the data they care about. But in actual operation, the operator of the substation pays attention to the information of the primary equipment. He should be able to get the information of the primary equipment when he sees the primary e...

[0003] Chinese patent (application number: 201010265470.2, patent name: dual-machine measurement and control main-standby online switching method), this patent discusses the data uploading of the monitoring direction and the command issuing of the control direction of the dual-machine measurement and control device, and provides a Switching method, but this method is mainly based on a state judgment and switching based on the hardware of the measurement and control device itself, and the monitoring data itself has a certain degree of independence, so the above method does not judge based on the characteristics of the data source itself, so substation design After the completion, it has some defects in the difference and the selection of data uploading when it is running, and it cannot complete the data comparison and uploading well.
