Power real-time data acquisition system based on multi-machine balanced synchronous on-line mode

Abstract

The invention relates to a power real-time data acquisition system based on a multi-machine balanced synchronous on-line mode, which comprises at least two prepositioned servers and two transformer station telecontrol devices. The prepositioned servers and the two transformer station telecontrol devices are connected together through a dispatching data special network. The system has the main technical characteristics that the prepositioned servers connected with the dispatching data special network are synchronously connected to two monitoring main networks, the two monitoring main networks are also synchronously connected to other two prepositioned servers, and the other two prepositioned servers are connected with the two transformer station telecontrol devices through the special line network. By combining at most 6 prepositioned servers and the two transformer station telecontrol devices into a double local area network system through the dispatching data special network and the special line network, the problems of one telecontrol device fault, one prepositioned server fault in a monitoring center, and data loss and beyond control during cross faults are effectively solved; and the reliability and stability of a data acquisition processing system are enhanced.

Description

Technical field [0001] The invention belongs to the field of electric power automatic control, in particular to a power real-time data acquisition system based on a multi-machine balanced simultaneous online mode. Background technique [0002] With the continuous development of computer networks and automatic control technology and the in-depth application in the power system, the automation degree of the power system is getting higher and higher, providing a reliable guarantee for the safe and stable operation of the power system, and at the same time for the intensification of substations Management, the realization of fewer people, no one on duty provides technical support. The construction of a monitoring center is an inevitable result of the realization of a small number of people and unattended power systems. In the operation mode of unattended substations and centralized monitoring and control of the monitoring center, the centralized control system must be required to be ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and propose a real-time power data acquisition system based on multi-machine balanced simultaneous online mode. The substation remote control device divided into active and standby forms a dual local area network through dispatching data private network and dedicated line network, which solves the problem of data loss and uncontrollability in the event of a remote control device failure in the substation, a front server failure in the monitoring center, and cross faults problems, enhance the reliability and stability of the data acquisition and processing system
