Embodiment
[0052] The distribution network damage probability assessment method under typhoon disaster based on analytical method, such as figure 1 shown, including the following steps:
[0053] Step 1, collect the attribute data of each component affected by the typhoon in the distribution network, and determine the failure probability of each component under typhoon weather conditions;
[0054] Step 2, according to the failure probability of each component in typhoon weather, determine the damage degree of the user's electricity consumption, and then determine the damage of the system in typhoon weather;
[0055] Step 3. Determine the power consumption damage level assessment based on the user's power consumption damage degree and the system damage situation, match the power consumption damage level with the historical data, and retrieve the same power consumption damage level in the historical data. Measures to repair the damage to the user's electricity consumption.

The invention discloses a method for evaluating the damage probability of a power distribution network under typhoon disasters based on an analytical method, which overcomes the defects in the prior art and comprises the following steps: step 1, collecting attribute data of each element influenced by typhoon in the power distribution network, and determining the fault probability of each element under the typhoon weather condition; 2, according to the fault probability of each element under the typhoon weather condition, determining the power utilization damage degree of the user, and then determining the damage condition of the system under the typhoon weather condition; and step 3, determining power utilization damage grade evaluation according to the power utilization damage degree of the user and the damage condition of the system, matching the power utilization damage grade with the historical data, and taking measures adopted by the same power utilization damage grade in the historical data to repair the power utilization damage condition of the user.
Description
technical field [0001] The invention relates to the technical field of power distribution systems, in particular to a method for evaluating the probability of damage to a power distribution network under a typhoon disaster based on an analytical method. Background technique [0002] The rapid development of social economy has made users increasingly dependent on electricity. The power distribution system connects the transmission system and users in the power system and plays an important role in the level of user reliability. Extreme weather has a huge impact on the power system, especially the widely distributed power distribution system. Therefore, it is necessary to evaluate and predict the possible losses of the power distribution system under typhoon disasters, so as to provide a theoretical reference for the government, power grid companies and other relevant departments and users to take countermeasures. At present, there is no clear and clear method to predict or e...
