Step S212, by the device type factor, fault category factor, history of the power distribution network included by history data
Data statistics factor, weather influence factor, equipment deficiency influence factor, overhaul management factor, repair time factor, site operation
Factor is multiplied with control measure factor, obtained product value as power distribution network cyclization threat probability values；That is,
The influence of cyclization threat probability values=device type factor * fault category factor * historical data statistical considerations * weather because
Plain * equipment deficiencies influence factor * overhaul managements factor * repair time factor * site operation factor * control measure factors
The acquisition of above-mentioned history data can refer to correlation technique realization, will not be repeated here.
Step S214, Loop Closing Operation consequence value is multiplied with cyclization threat probability values, and obtained product value is as power distribution network
Cyclization powered operation risk risk assessment value；That is,
Risk assessment value=Loop Closing Operation consequence value * cyclization threat probability values
Step S216, divides table according to risk class set in advance, determines the corresponding risk class of risk assessment value, with
Staff is set to judge whether to cyclization powered operation according to risk class.
For example, risk assessment value is divided as follows：
A. value-at-risk >=1200, are I grade of risk；
B.1200 ﹥ value-at-risk >=600, are II grade of risk；
C.600 ﹥ value-at-risk >=200, are III grade of risk.
These are only can divide other risk class forms in example, concrete application, such as rudimentary risk, intermediate wind
Danger, senior risk, highest risk etc., will not be repeated here.
Risk evaluation result can more intuitively be shown to the powered cyclization behaviour of execution power distribution network by the division of risk class
The relevant staff of work, can allow staff to have an entirety understanding to the risk for performing Loop Closing Operation, contribute to quick
Decide whether to perform powered Loop Closing Operation.In addition, can further include in the above method according to risk class provide whether
Perform the suggestion of powered cyclization powered operation.For example, when risk class is senior, then it is not recommended that performing powered cyclization data.
Further, the above method can also include generation cyclization powered operation Risk Assessment Report, and this report is sent
To server so that server is analyzed and handled to this report, be easy to staff have to the running status of power distribution network into
The understanding of one step, is adjusted according to this report to power distribution network, to lift the safety and reliability of distribution network operation, and then drops
The low cyclization powered operation risk to the power distribution network.
In the above method of the present embodiment, carrying out theory analysis by specific data, there is provided detailed theoretical calculation
