Description
Technical field
The utility model relates to power domain, is specifically related to a kind of transformer station tele-control system.
Background technology
In prior art, transformer station of unit generally adopts traditional relay to carry out protecting, controlling, and centralized control of can not networking can not concentrated expression electric power system fault.
Prior art traditional relay carries out protecting, controlling, and electric power system stability, reliability are poor, and once break down, can not concentrated expression electric power system fault, is unfavorable for electric power system integrated dispatch.
Utility model content
The purpose of this utility model is to provide a kind of transformer station tele-control system, to solve the poor technical problem of prior art Substation control engineering reliability.
For achieving the above object, the utility model provides a kind of transformer station tele-control system, a kind of transformer station tele-control system, comprises remote dispatching center and is connected with modulator-demodulator, described modulator-demodulator connects multiple connection equipment, and this multiple connection equipment connection is linked with the local monitoring station of printer; Multiple connection equipment connects CAN by multiple communication processor, and protection measuring and controlling node connects RS485 bus and CAN respectively.
A kind of transformer station tele-control system that the utility model provides, can ensure power system stability and optimizing operation.
Accompanying drawing explanation
Transformer station's tele-control system structure chart that Fig. 1 provides for the utility model.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of transformer station tele-control system, comprises remote dispatching center and is connected with modulator-demodulator, and described modulator-demodulator connects multiple connection equipment, and this multiple connection equipment connection is linked with the local monitoring station of printer; Multiple connection equipment connects CAN by multiple communication processor, and protection measuring and controlling node connects RS485 bus and CAN respectively.
The application of the remote regulator control system of RTU in electric power system is the technological transformation project that my unit independent research improves, after this project implementation, the remote regulator control system of improved RTU can be monitored in real time to the electric parameters of operational outfit and state, timely faults, and action is in alarm or tripping operation; To voltage, electric current, power, temperature, direct current, gear, deciliter state such as circuit breaker, disconnecting link is monitored in real time; Remote control operation is carried out to circuit breaker, electric knife gate etc.; Ensure power system stability and optimizing operation.
Substation Micro-Computer Automatic System adopts layered distribution type structure design, and system is divided into three layers on the whole: wall, communication layers, substation level.
Comprehensive automation system of transformer substation is equipped with CAN-BUS fieldbus and the two Network Communication interface of RS485 string line, Shielded Twisted Pair is used to carry out equipment room interconnection, during connection, order wire can not cross branch, is positioned at start node and terminal node should access terminal build-out resistor (120 Ω) to reduce the capable wave reflection of terminal signaling.
Substation level complete transformer station and scheduling and local monitor between information transmission.
The standard serial port (sending and receiving, three lines) that communication manager has RS232 is monitored and dispatching and monitoring communication with local.
Outside primary voltage, electric current are first after a high-voltage mutual inductor, the analog quantity access device being transformed to specified 100V, 5A, 1A exchanges module, exchange module and this tittle is changed into weak electric signal after conversion, by backboard, weak electric signal is sent to mainboard again, mainboard is analyzed supplying CPU after weak electric signal analog-to-digital conversion, is simultaneously displayed on liquid crystal display screen.After CPU judges, if any fault, send out alarm or trip signal, and corresponding failure is presented on liquid crystal display screen.
2) device shows collected amount, analyze, judges.As fault amount reaches operating value, through adjusting time delay, send alarm or trip signal.(device shows once, secondary voltage and once, secondary current, power, power factor etc.).
3) how to control circuit breaker: generally, device and the linear quadratic control part of circuit breaker only need three lines to be connected, breaking coil, closing coil, from device draw negative supply to secondary loop of breaker.Negative supply needed for circuit breaker must be drawn from device, thus after ensureing to disconnect this device DC control supply when such as interruption maintenance, guarantees that associated loop non-transformer exists; Also prevent the generation of crosstalk source phenomenon, leaving hidden danger for running later, being also inconvenient to search earth point when there is DC earthing.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not depart from the spirit and scope of technical solutions of the utility model.
