Summary of the invention
For overcoming above-mentioned deficiency, the invention provides a kind of feed line automatization system, its good stability, the reliability height can be realized troubleshooting at line layer, has the communication of many stipulations, remote monitoring function, and systems soft ware destructing compact and reasonable.
Feed line automatization system of the present invention comprises power distribution automation feed terminal unit, vacuum automatic distribution switch, network communication supervisor and real-time monitoring software.
The power distribution automation feed terminal unit is used to monitor the running status of panel switches on the post, finishes local troubleshooting, and real time data is passed to the network communication supervisor.The network communication supervisor is used for the real time data of power distribution automation feed terminal unit monitoring is handled, and then passes to the real-time monitoring software of power distribution automation.Monitoring software is analyzed the data that collect, judge in real time, to determine the running status of each panel switches.When distribution line broke down, the real time data analysis of monitoring software by uploading was used for the position and the displacement switch of failure judgement, realizes functions such as distant place communication, remote measurement.Feed terminal unit is made up of digital circuit, function circuit, initialization circuit, power supply, and line voltage, current signal that voltage, current transformer are gathered are given A/D converter after the amplification filtering.The conversion communication manager comprises computer, main treatment circuit, a plurality of upper communicating circuit, a plurality of the next communicating circuit, terminals and power supply.Main treatment circuit is connected with a plurality of the next communicating circuits with a plurality of upper communicating circuits by terminals, serial port circuit in the upper communicating circuit links to each other with computer by terminals, serial port circuit in the next communicating circuit is connected with apparatus output signal end on the distribution line by terminals, and upper communicating circuit has identical circuit structure with the next communicating circuit.Voltage-type vacuum automatic distribution switch comprise bushing current transformer, vacuum interrupter, switch and operating mechanism its.Its three-phase combined type, every phase vacuum interrupter serial connection isolation switch, and be in transmission connection by insulation axle and operating mechanism, operating mechanism and switch major loop are isolated by casing, and leave airtight passage, every phase two ends all are connected with lightning arrester, are penetrated with current transformer, pressure-fired gas is arranged in the seal case, be connected with the EP rubber seal on the casing.Monitoring software is made up of communication control module, power distribution automation real-time monitoring module, database management module, chart generation administration module, Real-Time Sharing Data Control module.
Compared with prior art, beneficial effect of the present invention is embodied in:
1, the characteristics of feed line automatization system dependence self voltage-type, realize troubleshooting by feed terminal unit at line layer, and carry out transfer of data by communication channel, implement remote monitoring, can accurately judge fault section and realize the automatic isolation of fault section at the distribution line layer, in time eliminate distribution network failure, improved grid automation level and power supply reliability.
2, the wireline audio communication modes is applied to power distribution automation, has not only improved the reliability of communication, and greatly reduce the construction investment of power distribution automation.
3, systems soft ware had both guaranteed the consistency of data because data sharing can be total to case between a plurality of modules, had also reduced redundancy; Data are in internal memory, and each module is quick to the operation of data, improved the execution speed and the efficient of system.This module has become to guarantee one of software systems key technology stable, reliable, efficiently operation.
