Embodiment Construction
[0016] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0017] A power real-time data acquisition system based on multi-machine balanced simultaneous online mode, such as figure 1 As shown, it includes four front-end servers (up to six) and two substation remote control devices. In this embodiment, four front-end servers are installed, and four front-end servers (up to six) are installed at the same time. Connected to two monitoring main networks, of which two front-end servers (up to four) are connected to two substation remote control devices through the dispatch data private network to form a local area network composed of the dispatch data private network. The set servers are connected to the dispatch data private network in the form of network card binding. The two front-end servers and the substation remote control device adopt the IEC60870-5-104 communication protocol for data communication; th...

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 ...
