Embodiment 1

[0069] Embodiment 1 of the present invention discloses a dispatching plan security check method, please refer to figure 1 , the dispatching plan safety check method includes:

[0070]S1: When a certain type of scheduling plan is received, according to the preset effective time range of fault screening, for each planning mode in the scheduling plan, it is judged whether the preset candidate fault screening section queue exists for Candidate fault screening sections for fault screening in the planning manner.

[0071] Wherein, the above-mentioned certain type of scheduling plan may specifically be any one of a real-time plan, an intraday plan, and a day-ahead plan.

[0072] In this embodiment, the section data included in the candidate fault screening sections in the preset candidate fault screening section queue is specifically the historical data of the result of the safety check of the scheduling plan, and more specifically, the section data of the above candidate fault scre...

Embodiment 2

[0114] Embodiment 2 of the present invention discloses a scheduling plan security check system, please refer to Figure 4 , the scheduling plan security checking system includes a judgment module 100, a screening module 200, a grouping module 300, an acquisition module 400, a first evaluation module 500, an update module 600, a second evaluation module 700 and a correction module 800, wherein:

[0115] The judging module 100 is configured to, when a certain type of scheduling plan is received, judge whether the preset candidate fault screening section queue is There are candidate fault screening sections for fault screening of said planned approach;

[0116] The screening module 200 is configured to use the candidate fault screening section to screen the predicted failure set of the planned method to obtain the predicted failure subset of the planned method, and to filter the predicted failure subset of the planned method if the judgment result is existence. Mark as a filtera...

Abstract

The invention discloses a scheduling plan security check method and system. When the method receives a certain type of scheduling plan, it can correspond to the planning mode in the scheduling plan according to the preset candidate fault screening section queue. After that, each planning method is grouped, and according to the distribution of the filterable planning methods in each group, the planning method that is prioritized for safety and stability assessment in each group is determined, and the planning method is evaluated, and based on the Carry out the evaluation result of the planning mode for evaluation, and perform fault screening and evaluation on other planning modes in the group, so as to realize the evaluation after fault screening of each planning mode in each planning mode group as much as possible; and the present invention utilizes safety checking The evaluation result data of the candidate fault screening section queue is updated synchronously to serve as the fault screening basis for the safety check of the dispatch plan, so that the present invention shortens the time-consuming rolling execution of the safety check of multiple dispatch plans.

Description

technical field [0001] The invention belongs to the technical field of power system operation control, and in particular relates to a dispatching plan safety check method and system. Background technique [0002] The power system dispatch plan directly serves the power system and provides necessary means for the safe and economical operation of the power system. Scheduling plans include real-time plans, intraday plans and day-ahead plans. Among them, real-time planning includes 12 planning methods, intraday planning includes 32 planning methods, and day-ahead planning includes 96 planning methods. [0003] In order to ensure the safety and stability of the planning method, it is necessary to check the safety of the dispatching plan. Specifically, when the power system is subject to various possible disturbances (a large number of expected failures), the safety and stability evaluation of the dispatching plan (that is, the simulation Calculation), check. However, if the sa...
