Detailed Description
To further describe the technical features and effects of the present invention, the present invention will be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1-4, a specific intelligent power restoration research and judgment method for a power distribution network based on multi-source information, the invention comprises the following steps: (a) aiming at a power failure event, when a corresponding fault switch receives a closing signal, the corresponding fault switch can directly trigger the power restoration research and judgment, and a dispatcher interface automatically pops up related prompt information and pushes a field emergency worker palm; (b) the dispatcher or the on-site emergency personnel initiatively initiates a power restoration study and judgment request, the self-system background power restoration study and judgment software carries out power restoration study and judgment according to the relevant information of the work order to be studied and judged, and the relevant information is pushed to the relevant personnel after the study and judgment is finished, such as interface or palm prompt. The research and judgment information comes from a plurality of systems such as a distribution network automation system, a GIS system, an electricity utilization information acquisition system and the like.
The method specifically comprises the following steps:
(1) trigger type retest study and judgment
The triggered power restoration study and judgment is mainly configured to assign a whole process that an own system (distribution automation system) receives a switch closing signal, actively triggers power restoration study and judgment and feeds back study and judgment results, as shown in fig. 2.
Description of the flow: when the distribution system receives a closing signal of the intelligent switch, the distributed power failure emergency repair items are actively traversed, and if the power failure emergency repair items can be inquired, specific power restoration research and judgment are carried out. Firstly, it is determined whether the switch (the switch is the first switch in the feeder power failure range) of the feeder and all the intelligent switches at the downstream of the switch are electrified or not, if the switch is not electrified, the information description of the power restoration failure and the specific switch non-electrification is fed back to related personnel, such as dispatcher interface display, pushing and controlling personnel, and the like. When all the intelligent switches are determined to be powered back, data follow-up reading verification is carried out on all distribution transformers at the downstream of the intelligent switches of the research and judgment feeder line, if the distribution transformer follow-up reading verification is normal, the success of power back of related personnel is fed back, otherwise, relevant information of power back failure and power distribution transformer non-power back is displayed on a dispatcher interface and a palm of the dispatching personnel is pushed
(2) On-demand type retest
The requested power restoration study and judgment mainly refers to a whole process that a power distribution first-aid repair worker initiatively initiates a power restoration study and judgment request through a palm machine or a dispatcher through an operation interface, and a self-system study and judgment module starts power restoration study and judgment and feeds back study and judgment results, and is specifically shown in fig. 3.
Description of the flow: after the self-distribution system receives a power restoration work order to be researched and judged, a feeder line power failure first switch is obtained through work order information, whether the switch and all the downstream intelligent switches of the power restoration research and judgment feeder line are electrified or not is determined firstly based on the first switch, if the condition that the switch is not powered, power restoration failure and the detailed switch non-power restoration information description are fed back to related personnel, such as dispatcher interface display, pushing of a palm of the power distribution and robbery personnel and the like. And when all the intelligent switches are determined to be power restoration, performing data follow-up reading verification on all the distribution transformers at the downstream of the switch of the research and judgment feeder line, if the distribution transformer follow-up reading verification is normal, feeding back the success of power restoration of related personnel, and otherwise, displaying the relevant information of power restoration failure and power restoration failure of the distribution transformer on a dispatcher interface and pushing a palm of the dispatching personnel.
In the process of the retelling judgment, data interaction is required to be carried out through an interface.
The power restoration study and judgment interactive interface is a communication interface designed for the power restoration study and judgment worksheet data interaction of the power restoration study and judgment system and the power restoration system, when the triggered power restoration study and judgment is adopted, the power restoration study and judgment system only needs to push study and judgment results to the power restoration system, and the process is shown as the second process in fig. 4; when the demand-type power restoration study and judgment is adopted, the power restoration study and judgment is initiated by the power allocation and rescue system, the power restoration work order to be studied and judged is actively pushed, the power allocation system combines the power allocation information and the load control information, the result of the power restoration study and judgment work order is returned after the analysis, and at the moment, the processes of the first step and the second step in the figure 4 are executed. Taking the whole process of the requested re-telegram study and judgment as an example, the self-service system and the service interface (re-telegram study and judgment result receiving interface and re-telegram study and judgment work order receiving interface) of the emergency system are respectively designed, and the triggered re-telegram study and judgment only needs to be performed by the re-telegram study and judgment result receiving interface.
The distribution system and the distribution and robbery system are communicated by adopting a WebService protocol, the distribution system provides a receiving service for a power restoration to-be-researched work order, and when the distribution and robbery system generates the power restoration to-be-researched work order, the interface of the distribution system is called to push the power restoration to-be-researched work order; the matching and robbing system provides a receiving service for the power restoration study and judgment worksheet, and when the matching and robbing system completes the study and judgment of the power restoration to-be-examined worksheet, the interface of the matching and robbing system is called to push the results of the power restoration study and judgment worksheet.
