Description

Power distribution network fault power failure recovery plan generation method
Technical Field
The invention relates to the technical field of distribution network operation and maintenance, in particular to a method for generating a power failure recovery plan of a power distribution network.
Background
In order to improve the reliability of power supply, the power distribution network often adopts a closed-loop design and an open-loop operation mode. When a local power failure occurs in the power distribution network, an operator usually transfers the power loss load of a non-fault area to the opposite side of a line through the interconnection switch after isolating the fault, so that power supply is restored to the non-fault area.
The whole recovery of the power loss load is the direction that power distribution network regulation and control are pursued in an effort continuously, and during the design of the existing power distribution network, due to the lack of comprehensive deep calculation of various transfer schemes, a quantitative scientific evaluation method is lacked for weak links of the power distribution network, the power distribution network is often excessively transformed according to line load rate indexes, the economic spread waste is caused, and sometimes the weak links of the power distribution network cannot be effectively improved.
The known feeder load rate index can only reflect the maximum power transfer and supply capacity which can be transferred to the opposite side after a single feeder is powered off, and can not comprehensively and objectively reflect the problem of insufficient capacity when a plurality of feeders are possibly transferred to a main transformer simultaneously when the transformer substation is completely stopped, and the main transformer load rate index only reflects the load bearing capacity of the main transformer and can not reflect the weak link which limits the load transfer and supply of the transformer substation after the transformer substation is completely stopped.
When a transformer substation is completely stopped, the problem of cross influence of the transfer capacity of a plurality of feeders and the load bearing capacity of a plurality of main transformers exists, and the weak link of the distribution network cannot be found comprehensively and accurately only by depending on the load rate indexes of the feeders and the main transformers, so that the improvement of the transfer capacity of the distribution network is limited, the transformation of the distribution network cannot be further quantitatively guided, when the transfer capacity is insufficient, part of power loss loads cannot be recovered effectively and quickly, and the customer satisfaction and the enterprise economic benefit are reduced.

(3.3) establishing an objective function
Figure BDA0002423841330000063
Wherein q is the number of main transformers to be supplied, XjThe load which can be recovered is supplied to the feeder j through multi-path transfer, d is the number of the multi-path feeders, and F' is the maximum load which can be recovered by the multi-path transfer of the power failure transformer substation; and (3.4) solving the optimal solution of the objective function, and solving by using a simplex method to obtain the maximum load F' which can be recovered by the power failure transformer substation through multi-path transfer. The expression of the objective function is established on the basis of the following conditions: a. different multi-path feeder lines can be transferred to the same main transformer; b. at least two multipath feeder transfer paths are provided. The distribution network operating the method of the embodiment should meet the above conditions.
(4) And establishing a plurality of multipath transfer schemes to obtain the transfer load quantity of each scheme. (5) And (5) evaluating and sequencing the multi-path transfer schemes to obtain an optimal multi-path transfer scheme, and taking the single-path feeder line transfer scheme and the optimal multi-path transfer scheme obtained in the step (2) and the step (5) as a power failure recovery plan.
If the optimal solution value is equal to the summary of all the single-path power failure loads of the transformer substation, the fact that weak links do not exist in the single-path feeder load supply of the transformer substation is shown. If the sum of the power failure loads of all the single paths of the transformer substation is less than the sum of the power failure loads of all the single paths of the transformer substation, it is indicated that weak links exist in some single-path feeder lines of the transformer substation.
(6) And (5) carrying out the steps (2) to (5) on all the substations in the power distribution network to obtain a power failure recovery plan of the power distribution network.
Whether the power loss load can be quickly transferred out after the power failure of the power distribution network is directly influenced by the transfer capacity of the power distribution network, and for a single feeder line, the transfer capacity is determined by the capacity of the feeder line and the margin after the transfer and is influenced by the load rate of a main transformer after the transfer. The load margin after the transfer generally determines whether a weak link exists in the feeder line. For a transformer substation, the load rate of a feeder line and the load rate of a main transformer cannot completely reflect the power transfer capacity of a power distribution network. The load rate index only indicates the acceptable ratio of load to capacity, and only reflects the capacity of a feeder line or a main transformer capable of bearing extra load; when a substation is completely stopped, even if all the load factors of the transfer lines are not overloaded, the main transformer after transfer is still overloaded. Whether the main transformer is overloaded or not is related to different transfer paths. Therefore, different transfer paths are transferred, and the allowed load amount is different, so that an optimal transfer scheme needs to be established.
Whether weak links exist in the power transfer capacity of the power distribution network or not is judged by taking the maximum value of the power transfer capacity of various power transfer schemes as an evaluation standard, if the maximum power transfer scheme still cannot meet the requirement of power loss load transfer, the weak links exist in the power distribution network, and targeted treatment measures such as transformation or change of a topological structure are required. The embodiment can effectively provide the power grid recovery plan under the most severe condition.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
