Technical Field
The invention relates to a power distribution network self-adaptive reconstruction strategy considering the power restoration benefits, and belongs to the technical field of power distribution networks.
Background
With the continuous expansion of the scale of the power distribution network and the improvement of the requirement of the power load on the power supply reliability, the realization of the quick and effective fault power restoration operation becomes an important target of the power distribution network. Reclosing is an important way for realizing power restoration, and in some power distribution networks, a power supply switching way is also provided for realizing power restoration. How to select the appropriate power supply switching mode is the key to conducting the power recovery operation.
In the existing method, the situation of failure rate is considered, the proportion of instantaneous failure of the overhead line is high, and the reclosing mode is often adopted to realize the power recovery operation; the proportion of the instantaneous fault of the cable line is small, and when the cable line has a switching condition, the power supply is recovered without adopting a reclosing mode, and the power failure time is shortened by adopting a rapid switching strategy. The disadvantages of the prior art mainly include two aspects: firstly, under the condition of the hybrid connection of an overhead line and a cable line, the evaluation of how to select a complex power mode lacks a standard; secondly, the switch configuration levels are uneven, the switch with controllable conditions influences the influence range of fault power failure, and the load level distribution also influences the decision of power restoration. Considering the switch configuration condition, the load level change and the actual operation mode, a self-adaptive complex power decision selection method needs to be formed.
