Embodiment
Below in conjunction with accompanying drawing, preferred embodiment is elaborated.Should be emphasized that following explanation only is exemplary, rather than in order to limit the scope of the invention and to use.
1, the monitoring method that combines of friendship/stream:
High-tension current source schematic diagram is seen Fig. 2, when distribution generation singlephase earth fault, at first inject direct current signal to faulty line, promptly adopt the direct current monitoring method, because the direct current monitoring method is not subjected to the influence of circuit branch, line mutual-ground capacitor, stake resistance, so can determine fault branch and section fast.
And then adopt the interchange monitoring method, and promptly inject AC signal to faulty line, because the AC signal monitoring can be adopted the magnetic induction method, promptly adopt instrument at ground monitoring, easily the localization of faults.
2, digital line terminal:
Schematic diagram is seen Fig. 3, finishes data acquisition, fault judgement and remote data and transmits, and mainly adopts 16 single-chip microcomputer MSP430 of little power consumption, micro power consumption wireless communication module nRF2401, and two-way, how main wireless communication network technology is provided; Realize direct current and AC sampling; Realized two-part phase-to phase fault current protection; One-phase ground protection based on signal injects reports short-circuit current, load current and line-to-ground electric field simultaneously.
3, data acquisition unit (DCU):
Bear the communication contact of digital line terminal and monitor supervision platform, schematic diagram is seen Fig. 4, mainly constitute by 16 single-chip microcomputer MSP430 of little power consumption, micro power consumption wireless communication module nRF2401, GPRS communication module etc., two-way, how main wireless communication network and long-range GPRS mechanics of communication are provided, possess on-line monitoring and distribution automation interface function.
4, localization of fault and monitoring system (monitor supervision platform)
Constitute by background computer and special software, adopt ethernet communication, receive, show, analyze and upload data, show the distribution line topological relation,, determine fault branch and section by comprehensive criterion.Also can adopt network to be connected with scheduling station power distribution network data acquisition and monitoring/Geographic Information System SCADA/GIS (Supervisor Control And Data Acquisition/Geographic Information System), it is more directly perceived that fault section is shown.
With Fig. 5 is example explanation localization of fault and on-line monitoring system embodiment:
The installation configuration of automatic station-keeping system:
Digital line terminal: basic routing line is according to the installation that distributes of distance equipartition principle, and every group is three.Every branched line is installed one group at least, and long branched line is again according to the installation that distributes of distance equipartition principle.
Data acquisition unit: the minimum one group of track data terminal (three) of being with of data collector, be with ten groups (in 100 meters scopes, do not have and block thing) at most.
Localization of fault and monitoring system (monitor supervision platform): a cover is installed in duty room.
When circuit normally moved, this system can show and write down load current and line voltage distribution in real time; When system's generation singlephase earth fault, open-circuit line isolating switch DL at first, then, the high-tension current source is dropped into, at first give faulty line input dc power stream, data terminal DT (Digital Terminal) uploads to control desk with the DC current data by data acquisition unit DCU (Data Collection Unit), control desk " localization of fault and supervisory system ", the path of flowing through according to DC current, carry out topological analysis, determine the event of failure information of fault section and fault-time, and record trouble information, can also abort situation information be sent on related personnel's mobile phone by the mode of global system for mobile communications GSM (Global System for Mobile Communications) short message simultaneously, help the maintenance personal to rush towards the scene rapidly.After the maintenance personal is on the scene, change signal source output into interchange output, output current is remained unchanged, the field staff adopts the magnetic induction method, uses the AC signal monitoring equipment, continues to search earth point along fault section, can find earth point easily, fix a breakdown.
