Detailed description of the invention
Fig. 1 is the flow diagram of the method for the present invention.
Specific embodiment
Below in conjunction with the attached drawing in the present invention, technical solution of the present invention is clearly and completely described, it is clear that
Described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the implementation in the present invention
Example, those of ordinary skill in the art's all other embodiment obtained under the conditions of not making creative work belong to
The scope of protection of the invention.
As shown in Figure 1, the present invention provides a kind of Dispatcher Power Flow calculation method based on cloud computing, include the following steps,
Step (1), user log in trend homepage, form independent Load flow calculation resource.
Further, for user before using Load flow calculation, on-line operation can be set out in scheduling controlling plateform system
Trend resource；User's selection is directly entered Load flow calculation, and system is equal according to the load of already existing trend resource and system
Weigh situation, starts new trend resource automatically in node and names the trend resource automatically, to guarantee each user's trend operation
Between it is unaffected.Alternatively, user can also be after logging in trend homepage, customized one new trend resource name, with
It is easy-to-look-up.New trend resource is mutually indepedent with existing trend resource.
Step (2) is embedded with the relevant information of region, plant stand and equipment in trend homepage, is used for user's quick search
It with positioning to relevant region, plant stand and equipment, and easily carries out trend mode and adjusts operation, obtain Load flow calculation information.
Further, it can be directly switch to region, plant stand and equipment in Load flow calculation homepage, do not need to carry out more
Secondary switching.
On corresponding region pel, user can check the power output and load of current region, and user can on this basis
The power output and load in the region are adjusted with the size of direct pull pel, and the area can also be directly switch into the pel of region
In plant stand catalogue under domain, the stoppage in transit that the power output load adjustment, route main transformer of generator load are carried out in plant stand figure puts into operation
Trend operation, and carry out Load flow calculation.
Step (3) zone of responsibility according to belonging to user and is pushed out use according to out-of-limit rate in trend homepage from high to low
Trend within the affiliated zone of responsibility in family is out-of-limit and transinformation.After the completion of Load flow calculation, duty that system is logged according to active user
Appoint area's information, out-of-limit and transfer the Power Flow Information being pushed out from high to low in the user responsibility area according to out-of-limit rate.Here
Out-of-limit rate refers to the out-of-limit severity of trend.
Step (4), user get over limit information according to the trend of Load flow calculation and are directly viewable out-of-limit adjustable strategies.User according to
The more limit information of current Load flow calculation clicks directly on the optimum apjustment strategy checked and eliminate the out-of-limit facility information, is rapidly performed by
Decision.
Step (5), after trend is not used for a long time or clicks cancellation by user, system discharges the Load flow calculation resource.It adjusts
Degree control system will record the time of each trend asset creation, if user is more than that regulation trend provides using the time of trend resource
Source longest time or user manually nullify this trend resource, and regulator control system will discharge this trend resource.
The present invention carries out the information of Load flow calculation acquisition after adjusting according to trend mode, directly list whole in homepage
The trend in region is out-of-limit and power flow transfer information, the trend of user's affiliated area get over clicked on limit information can check it is out-of-limit
Adjustable strategies need to switch in layer page lookup, effectively raise dispatching efficiency compared with traditional trend.
The present invention provides a kind of Dispatcher Power Flow calculation method based on cloud computing, should for traditional Dispatcher Power Flow
Method can support multi-user operation and mutually not by shadow according to the computing resource of the automatic allocation schedule person's trend of user information
It rings, calculation of tidal current that can be different according to user information pushing；It is out-of-limit, again in trend that cloud terminal pays close attention to dispatcher
The information such as load, transfer concentrate on a key frame, and inquiry, operation are integrated in same key frame, are using Load flow calculation
The operation of equipment, calculated result can be facilitated the functions such as to check when function, off-line calculation is more in line in use habit
The use habit of application requirement and user, therefore perfect in shape and function of this method as Load flow calculation, have a good application prospect.
Basic principles and main features and advantage of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
