Description
Technical field
The utility model relates to a kind of distribution network failure process, load safeguards system.
Background technology
In prior art to the precautionary measures of power distribution network and troubleshooting all fairly simple, be all utilize power distribution automation main station system to carry out remote monitoring, operation mostly, and practicality is not good enough, and for the treatment measures that some special circumstances do not have some complete.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, provide a kind of fault section and isolation accurately, the distribution network failure process of good stability, load safeguards system.
It is that a kind of distribution network failure process, load safeguards system, comprise data acquisition system, fault processing module, load assurance module and the equipment that restores electricity that the utility model solves the technical scheme that its technical problem adopts;
The coordination and control of the network topology data of described data acquisition system power distribution network, distribution network failure current data, power distribution network 10kV busbar voltage data and statistics, functional module;
Described fault processing module can carry out breakdown judge for the data of data acquisition system, and carry out fast processing, and can ensure that more load is powered and the power supply of important load as far as possible, can guarantee that system safety and the normal electricity consumption of user are not affected substantially;
Described load assurance module carries out according to the troubleshooting that fault processing module is made the load mating corresponding power distribution network;
The described equipment of restoring electricity takes appropriate measures when can recover after the process of load assurance module the safe and stable operation of safeguards system.
Further, described fault processing module comprises for power distribution network internal fault, and the fault current information collected by terminal is accurately located power distribution network internal fault, and the switch at rapid open failure two ends, fault is isolated; For power distribution network 10kV busbar fault, judge whether power distribution network 10kV bus breaks down by judging whether 10kV busbar voltage sharply declines, if broken down, the connecting valve disconnecting power distribution network and bulk power grid makes power distribution network and bulk power grid depart from.
Further, described load assurance module is for power distribution network internal fault, and by cut-offfing of operation interconnection switch, the load that power distribution network is lost is minimum; For power distribution network 10kV busbar fault, ensured the power supply of load by the islet operation of distributed power source.
Compared with prior art, the utility model structure is simple, low cost of manufacture; Fault section and isolation, distributed generator islanding run and combine, fault section and isolation can be carried out fast, dead electricity load can be recovered to greatest extent, accomplish not dead electricity of trying one's best, lack dead electricity as far as possible, the safe and stable operation of the safeguards system that simultaneously can take appropriate measures when service restoration, agrees with the needs of power distribution network actual motion.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
With reference to accompanying drawing 1, this enforcement comprises data acquisition system 1, fault processing module 2, load assurance module 3 and the equipment 4 that restores electricity;
Data acquisition system 1 gathers the coordination and control of the network topology data of power distribution network, distribution network failure current data, power distribution network 10kV busbar voltage data and statistics, each functional module;
The data that fault processing module 2 can gather for data acquisition system 1 carry out breakdown judge, and carry out fast processing, and can ensure that more load is powered and the power supply of important load as far as possible, can guarantee that system safety and the normal electricity consumption of user are not affected substantially; By the data that data acquisition system 1 gathers, carry out breakdown judge, if collect distribution network failure current data, power distribution network inside there occurs fault, if the 10kV busbar voltage data gathered are far below numerical value under normal circumstances, namely there occurs voltage collapse, then power distribution network 10kV bus there occurs fault; Crucial part of the present invention is that distribution network failure electric current and the rapid drawdown of 10kV busbar voltage can not occur simultaneously, utilizes this feature well can carry out the judgement of fault.
Load assurance module 3 carries out according to the troubleshooting that fault processing module 2 is made the load mating corresponding power distribution network;
Restore electricity the safe and stable operation of safeguards system of taking appropriate measures when equipment 4 can recover after the process of load assurance module.
Fault processing module 2 comprises for power distribution network internal fault, and the fault current information collected by data acquisition system 1 is accurately located power distribution network internal fault, and the switch at rapid open failure two ends, fault is isolated; For power distribution network 10kV busbar fault, judge whether power distribution network 10kV bus breaks down by judging whether 10kV busbar voltage sharply declines, if broken down, the connecting valve disconnecting power distribution network and bulk power grid makes power distribution network and bulk power grid depart from;
Load assurance module 4 is for power distribution network internal fault, and by cut-offfing of operation interconnection switch, the load that power distribution network is lost is minimum; For power distribution network 10kV busbar fault, ensured the power supply of load by the islet operation of distributed power source.
The utility model integrates distribution network failure process and load ensures, fault section and isolation can be carried out as early as possible, dead electricity load can be recovered to greatest extent, accomplish not dead electricity of trying one's best, lack dead electricity as far as possible, the safe and stable operation of the safeguards system that simultaneously can take appropriate measures when recovering, agrees with the needs of power distribution network actual motion.
