Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Power system operation mode is the core of power network safety operation.Under integrated scheduling method, the equipment of electrical network is adjusted pipe by multi-stage scheduling unit, China be divided into from top to bottom state's tune, network regulation, province adjust, adjust, county adjusts 5 grades.Because the method for operation need to be considered the factors such as workload demand, power station water situation, following weather condition of the whole province and even the whole network, therefore need to carry out between the superior and the subordinate's scheduling mode mutual, the reliability of calculating in assurance mode.When the mutual general mutual form of text that adopts of previous mode, inefficiency, and easily make mistakes.The present invention proposes under multi-stage scheduling pattern, upper and lower level scheduling mode issues and the method merging, by higher level's dispatching down distributing mode, subordinate, dispatched alter mode and be committed to higher level and dispatch, the Update Table of submitting to according to subordinate, integrates mode data automatically.
The basic thought of this programme is to adopt strict authority to control the data based Qi Tiaoguan mechanism in the method for operation, and each scheduling institution can only be adjusted the equipment operating data of its pipe of adjusting.
Set up basic data maintenance database, by the data maintenance of electrical network computing equipment, in basic database, as shown in Figure 1, higher level's scheduling is in charge of its straight tune equipment and is managed each subordinate's scheduling of its jurisdiction, and it oneself adjusts the equipment of pipe subordinate's management and running.
According to the corresponding relation of equipment and card, determine the network model parameter (being BPA card) that Ge Tiaoguan unit can directly manage.
Higher level scheduling, according to operation of power networks demand, is adjusted the operational factor of its tube apparatus of adjusting, and then selects to walk abreast or serial strategy is issued to each subordinate's scheduling institution by mode.
On the basis of the mode issuing higher level, subordinate's scheduling is according to operation of power networks demand, network model data are adjusted, because each equipment has clear and definite tune pipe authority, each subordinate's scheduling can only be modified to the equipment operational factor of its pipe of adjusting, and can not revise the equipment of higher level's scheduling or other subordinate's dispatching office tune pipe.
As shown in Figure 3, the mode issuing for paralleling tactic, each subordinate's scheduling can be modified to network model parameter simultaneously, subordinate's scheduling institution is in self adjusts the extent of competence of tube apparatus, on the mode basis issuing in higher level's scheduling institution, according to operation of power networks requirement, revise the corresponding method of operation, when the method for operation is revised in subordinate's scheduling, according to user's operation, automatically the model parameter that the model parameter of subordinate's scheduling operation being crossed and higher level issue compares, recording subordinate's scheduling increases, delete, the model data changing, after pass-through mode trend stability Calculation, to increase, delete, change model data and be committed to higher level's scheduling, it is the just differentiation content of relatively basic mode that subordinate's scheduling is submitted to higher level's scheduling, due to according to thread-equipment-network model corresponding relation, set each its corresponding Tiao Guan unit of network model data, only have its corresponding Tiao Guan unit just to there is authority and revise corresponding data, so the mode that each subordinate's scheduling institution is submitted to does not have data collision.When the merging of network model data is carried out in higher level's scheduling, the differentiation content of one by one each subordinate's scheduling being submitted to merges, and concrete steps are:
1) extract the differentiation content that the scheduling of Yi Ge subordinate is submitted to, and trend is separately processed with stable
2) if current merging be the content of first subordinate scheduling, the mode of higher level dispatching down distributing is benchmark mode; Otherwise the mode having merged before of take is benchmark mode;
3) for the content increasing, search the position of a last card of network model card that in benchmark mode, current merging tube apparatus that scheduling institution is adjusted is corresponding, and after adding the card of increase to this card position;
4) for the content of deleting, search each and delete card each card in benchmark mode, adopt the card annotate method of PSD-BPA, before this card, add ". " and comment out this card, to represent deletion;
5), for the content of revising, find the card that each revises card correspondence in benchmark mode, and the card in benchmark mode is replaced with to the card after revising;
6) after trend and stable file operation are completed increasing, delete, change, dat file after the trend calculation command PFNT.exe file that calls PSD-BPA is combined carries out trend calculating, if trend is calculated, pass through, the swi file further calling after stability Calculation order SWNT.exe is combined calculates.If trend and stability Calculation can be passed through, forward step 7) to; If trend is calculated not restrain maybe, cannot carry out stability Calculation, remind higher level's despatching work personnel, network model parameter is adjusted, until can complete trend and stability Calculation, then forward step 7) to;
7) if also have scheduling institution not merge, get back to step 1) and continue to merge next scheduling institution, otherwise merge, finish.
As shown in Figure 4, mode for serial policy distribution, the order that each subordinate's scheduling of determining while issuing according to mode is made, the subordinate's scheduling ranking the first can be modified to mode, after calculating by PSD-BPA, mode is committed to higher level's scheduling, after subordinate submits to successfully, automatically open the authority of next scheduling alter mode, be so progressively modified to last subordinate's scheduling way of submission.
When equipment operating data is revised in scheduling at different levels, according to the data area requirement to each card in BPA, the data that detect an operational outfit card whether in effective range, if not in effective range or recommend in numerical range, sub-category prompting.As exerted oneself for generated power, be greater than the maximum meritorious situation about processing of generator, remind as mistake, the load or burden without work that burden with power is less than 2 times for node, warn, for wrong situation, must modify to corresponding data, to guarantee data in the reasonable scope, thus the validity of assurance user Update Table.
Below in conjunction with an example, the invention will be further described.
1. higher level's dispatching of power netwoks starts power system operating mode network model integration system;
2. select corresponding mode, click " issuing ", select corresponding distributing policy (take paralleling tactic as example), be set the closing time that subordinate's scheduling institution is submitted to, click and determine, power system operating mode is issued to subordinate's scheduling.
3. subordinate's scheduling institution enters system, according to system alert, open the mode of higher level's dispatching down distributing, and according to adjust pipe area power grid practical operation situation, alter mode network model data, after PSD-BPA trend, stability Calculation, click and submit to, mode network model data can be committed to higher level's scheduling.
4. after subordinate's scheduling institution has been submitted to, higher level's scheduling institution enters system, choose the mode having issued, click and merge, system is issuing the mode that merges the scheduling institution submission of all subordinates on the basis of mode automatically, network model data are slightly adjusted, after PSD-BPA trend, stability Calculation, complete power system operating mode network model Data Integration.
