Technical field
The present invention relates to electric power network technique field is and in particular to a kind of distribution network failure of distribution network failure detection method detection side
Method.
Background technology
China's power distribution network has that line construction is complicated, the various changeable, spy such as faults frequent is complicated, maintenance workload is big of environment
Levy.A certain section of distribution line breaks down, and needs to investigate fault generation position paragraph by paragraph, not only working strength is big, but also can prolong
By mistake emergency repair time, affects power supply reliability, and in actual use, line voltage is to household electrical appliance, industrial automation equipment, medical
The normal use of the electric network terminal equipment such as instrument and meter and service life have a very big impact.At present, the fluctuation of line voltage
Larger, especially in rural area, the fluctuation of line voltage is bigger；Too high line voltage often shortens making of electric network terminal equipment
With the life-span, sometimes even electric network terminal equipment can be made to burn；And too low line voltage is then likely to result in electric network terminal
Equipment cisco unity malfunction.Currently used detecting system and its detection method, can only be rough fault coverage is detected, and
Timely and effectively failure cause and trouble point can not be confirmed and be analyzed and processed.
Content of the invention

（2）The current information of acquisition, status information of equipment and switch motion information are analyzed processing；
（3）By the current information after processing, status information of equipment and switch motion information and distribution terminal pre-set threshold value information phase
Relatively, if exceeding setting range, warning device is reported to the police, if it is not, then continuing next step；
（4）Obtain switch motion information, judge the multiple action of switch, the multiple action of switch is integrated into a switch motion
Information；
（5）Switch motion information and power distribution network being preset desired value compare, if exceeding preset value, judging distribution network failure；
（6）In the case of detecting that power distribution network breaks down, display screen shows the faulty line in power distribution network, and obtains
Terminal corresponding to faulty line；And send fault cues message to distribution terminal.
Described step（5）With（6）Between further comprising the steps of：
（7）Detection power distribution network in whether foreign matter occurs just on the circuit of distribution, wherein, detect described just distribution line
In the case of foreign matter occurring on road, determine that power distribution network breaks down；
（8）In detection power distribution network, whether the electric current just on the circuit of distribution undergos mutation, prominent detecting that described electric current occurs
In the case of change, determine that power distribution network breaks down.
The invention has the beneficial effects as follows：Present invention achieves effectively being monitored to whole station secondary device running status, have
Effect reduces artificial regular inspection project, reduces the maintenance power off time of equipment, improves reliability and operating efficiency.Can accurately judge simultaneously
Whether power system is broken down or is had unusual service condition, therefore, it is possible to reliably carry out relay protection to power system.
