Technical field
The invention belongs to electric system figure display technique field, be specifically related to a kind of sensitivity analysis for energy management system methods of exhibiting as a result.
Background technology
Energy management system (Energy Management System) is that to take computer technology and electric system application software technology be the modern power systems complex automatic system supported, and is also the integrated or integrated of energy system and infosystem." management " refers to the integrated management to different automated systems, and it is to replace the analog computation technology with Digital Computing, with software, realizes that most of function replacement is embodied as feature with hardware.The energy management of narrow sense specially refers to Generation Control and generation schedule.General EMS should comprise Data Collection, energy management and the large function of network analysis three.The EMS of broad sense also should comprise dispatcher training system DTS(Dispatcher Training Simulator) function.EMS is mainly towards generating and the dispatching center of transmission system Ji great district level electrical network and provincial power network.
In electric power system tide is analyzed, sometimes not only to try to achieve the trend solution, and when needing to analyze some variable and changing, can cause that great variation occurs other variable, at this moment just need to carry out sensitivity analysis.The various amounts of trend become sensitivity as the degree of influencing each other between line power and generated power, sensitivity analysis is actually for describing the amount of the linear relationship between the power flow equation variable, and it is widely used in fields such as Contingency Analysis of Power Systems, Optimal Power Flow and Electric Power Network Planning.
In existing energy management system, man-machine interface is browsed subsystem and is showed the sensitivity analysis result for every kind of sensitivity watch type by two lists, one of them list means the list of sensitivity monitored object, another list means sensitivity table as a result, when when a monitored object is selected in the list of sensitivity monitored object, the list meeting shows relative sensitivity analysis result, the exhibition method of this deflection word is very not directly perceived, can't directly effectively help the yardman to carry out assistant analysis.
Summary of the invention

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1, the invention provides a kind of sensitivity analysis for energy management system methods of exhibiting as a result, said method comprising the steps of:
Step 1: create the sensitivity analysis result and show pel;
Step 2: the sensitivity analysis result dynamically refreshes in real time;
Step 3: change the sensitivity analysis object, re-start the sensitivity analysis result and show.
Described step 1 comprises the following steps:
Step 1-1: enter tidal current chart, select the sensitivity watch type, and select the sensitivity analysis object;
Step 1-2: read the sensitivity analysis result of described sensitivity analysis object, and the sensitivity analysis result is sorted;
Step 1-3: read in configuration information, create the sensitivity analysis result according to the sensitivity analysis result and show pel, and the relevant position that is presented at tidal current chart adjusted equipment is (for conditioning equipment is generator, owing to generally only putting the plant stand schematic symbols on tidal current chart, so the position of conditioning equipment is exactly the center of plant stand under generator).
In described step 1-1, the sensitivity watch type comprises sensitivity watch type that line load exerts oneself to generated power, sensitivity watch type that the load of branch road group is exerted oneself to generated power and the busbar voltage sensitivity watch type to generator reactive.
Described sensitivity analysis object comprises circuit, branch road group and bus.
Described sensitivity analysis result comprises positive sensitivity analysis result and negative sensitivity analysis result; Align the sensitivity analysis result and negative sensitivity analysis result is sorted respectively; Described sensitivity analysis result is showed the digitized representation sensitivity sequence size in pel, and described sensitivity sequence size represents that the adjusting of conditioning equipment affects the big or small degree of institute's surveillance equipment.
In described step 1-3, from CONFIG.SYS, read in configuration information, described configuration information comprises the maximum number shown after positive and negative sensitivity analysis sort result, positive sensitivity color, negative sensitivity color and sensitivity analysis exploded view elemental size size as a result.
Described sensitivity analysis result shows that pel comprises positive sensitivity analysis result displaying pel and negative sensitivity analysis result displaying pel;
Described sensitivity analysis result is showed the direction of arrow representative adjusting direction in pel;
The direction of arrow that described positive sensitivity analysis result is showed pel under sensing, when surface modulation equipment is regulated by large toward minor adjustment (for the meritorious sensitivity analysis that generated power is exerted oneself of circuit, reduce circuit if need meritorious, gaining merit of conditioning equipment generator must be regulated toward little direction).
The direction of arrow that described negative sensitivity analysis result is showed pel from sensing, when surface modulation equipment is regulated from little toward large the adjusting (for the meritorious sensitivity analysis that generated power is exerted oneself of circuit, reduce circuit if need meritorious, gaining merit of conditioning equipment generator must be regulated toward large direction).
For the maximum number after positive and negative sensitivity sequencing display, positive and negative sensitivity corresponding color all can configure separately.
Described conditioning equipment is generator, and the position of conditioning equipment is plant stand residing center in the tidal current chart picture under generator.
In described step 2, obtain the sensitivity analysis result relevant to selected sensitivity analysis object table as a result from sensitivity analysis, positive and negative sensitivity analysis result is resequenced, and again create the sensitivity analysis result and show pel, and be presented at the corresponding position of tidal current chart adjusted equipment, realize that the sensitivity analysis result dynamically refreshes in real time.
In described step 3, while changing the sensitivity analysis object, sensitivity analysis result is before showed to pel removes from picture, and again obtain the sensitivity analysis result, and positive and negative sensitivity analysis result is sorted, create the sensitivity analysis result and show pel, and be presented at the corresponding position of tidal current chart adjusted equipment.
When mouse-over is on visual pel, application program is judged the visual pel hovered, and the detailed visual information in buffer memory (title, the level of sensitivity that comprise analytic target and controlled plant) is pointed out by Tip.
Showed the sensitivity analysis object information by visual pel, specific features: for each selected monitored object creates a series of visual presentation pel, by unified system load flow figure, showed, the pel created has dynamically, gradual change, transparent, three-dimensional texts feature, be provided in addition the function of hovering on pel, can check more detailed information.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment, the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of claim scope of the present invention.
