The special communication server apparatus is provided with 28 communication ports, which is far more than the number of the PC ports, thereby more RTU apparatuses can be connected.
Description
One, technical field:
Substation automation supervisory control system of the present invention, what relate to is distributed, layering watch-dog technical field at substation data collection and control.Be used for transformer station and subordinate electric substation.
Two, background technology:
At present, automatic monitoring system of transformer substation mainly contains dual mode, one is realized the data acquisition of whole transformer station, is finished the controlled function of transformer station by the supervisory control system PC by configuration analog quantity, semaphore input and output facility, promptly concentrate collection, centralized control, the main limit that lacks of this mode is; Poor reliability, the operation of whole electric substation all may be influenced when data acquisition equipment breaks down; It is two at inlet wire, female connection, feed configuration RTU equipment; finish data acquisition, protection, controlled function by RTU equipment; PC directly and RTU equipment inlet wire communication modes finish whole substation automation function; this side's the main limit that lacks is: when RTU equipment more for a long time; the load of PC can increase; cause the PC operation slowly, influence the normal operation of whole system.
Three, summary of the invention:
The objective of the invention is to overcome the defective of prior art; design a kind of communication server connection line protective device or motor protecting device or soft starter of passing through also by they access users separately, form the automatic monitoring system of transformer substation of the installation layered distribution type of complete Automatic monitoring systems.Its technology is to realize like this, comprise PC, line protective devices, motor protecting device, soft starter, measuring circuit, control circuit, the protection loop is in interior structure, it is characterized in that: the set background PC computer of transformer station connects communication server by Ethernet, communication server can the connection line protective device, motor protecting device, soft starter, line protective devices connect the measuring circuit module respectively, control circuit, the protection loop, a communication server in the whole device is provided with 28 communication ports, can insert wall protective device or motor protecting device or soft starter as required, advantage and the effect implemented after this technology are: reliability height: adopted the layered distribution type network configuration, each interlayer connects by communication modes, the interlayer function clearly gradually, any one deck equipment fault all can not influence the realization of the basic distributing function of electric substation; Response speed is fast: adopted special-purpose communication server equipment, finished communication with RTU equipment by communication server, after communication server collects the RTU device data, through calculating with filter after be forwarded to PC, can reduce the amount of calculation and the transmission volume of PC; Power system capacity is big: special-purpose communication server equipment has 28 communication ports, far more than the PC port number, can connect more RTU equipment.
Four, description of drawings
Fig. 1 is a structural representation of the present invention;
Wherein, 1-background PC computer, 2-communication server, 3-line protective devices, 4-motor protecting device, 5-soft starter, 6-measuring circuit, 7-control circuit, 8-protection loop, 9-measuring circuit, 10-control circuit, 11-protect loop, 12-motor;
Five, embodiment
Is example below in conjunction with accompanying drawing with the motor protection, and the present invention is further described;
See accompanying drawing 1; the set background PC computer (1) of transformer station connects communication server (2) by Ethernet; (2) three interfaces of communication server are connection line protective device (3) respectively; motor protecting device (4); soft starter (5); line protective devices (3) connect measuring circuit module (6) respectively; control circuit (7); protection loop (8); motor protecting device (4) is through measuring circuit module (9); control circuit (10); protection loop (11) connects motor (12); line protective devices (3) connect auxiliary power consumption equipment, and soft starter (5) connects motor (12).
