By simulation result be output to file include with common tree-like, enhanced edition is tree-like or console output type it is tree-like show it is imitative
Very as a result, and being output to text by corresponding simulation result and by the error-free final power grid logic control script preservation of emulation detection
Part.
After method and system provided by the invention can load script file, progress format error detection first is not asked
After topic again individually or batch load electric network model file or power flow files, so that it may carry out examining to script file for batch
Survey and shown in a manner of visual testing result ensure it is errorless after, carry out emulation and with visual means show simulation result,
Output result is finally subjected to text preservation
There are three types of script exhibition methods for software of the invention: 1) common tree-like result is shown；2) the tree-like result exhibition of enhanced edition
Show；3) the tree-like result of console output type is shown.Wherein shown in scripting editing and load using the tree-like result of enhanced edition.So as to
Hommization is shown and facilitates relevant operation
Here is one embodiment of the logic control script of dragon's fountain station security control device strategy:
IF $ (dragon bucket any line stoppage in transit mode)
THEN
<dragon's fountain station security control device strategy output=cutgen [] type=clb>
@！Conditions Condition output
@N/A $ (dragon bucket section) string ' kqjz', $ (abyb), " Three Gorges the first from left power plant " }
$-MW-
FAULT (state's tune dragon bucket I line)==enum@2500 > P of FaultK () >=2,100 1
FAULT (state's tune dragon bucket I line)==enum@2900 > P of FaultK () >=2,500 2
FAULT (state's tune dragon bucket III line)==enum@FaultK P () >=2,900 3
</Longquan Station Safety Control Device Strategy>
ENDIF
It struggles against under the method for operation that any line is stopped transport from knowing that its expression is meant in above-mentioned script in dragon, control is pacified at dragon's fountain station
If state's tune dragon bucket I line failure and power is between 2100MW and 2500MW in device Policy Table, Three Gorges the first from left power plant needs
Cut off a unit；If state's tune dragon bucket I line failure and power is between 2500MW and 2900MW, Three Gorges the first from left power plant is needed
Cut off two units；If state's tune dragon bucket III line failure and power are greater than 2900MW, Three Gorges the first from left power plant needs to cut off
Three units.It is steady to subsequent power grid that different unit output and number of units are cut off under different operating conditions after different faults in grid simulation
Determining simulation result can all make a difference, and need through script expressed intact power grid control logic.
Machine is such as cut in the behavior that equipment is controlled in power grid peace control strategy and the setting of cutting load control parameter can be with larger shadow
It rings to simulation result stable after electric network fault.By taking the parameter setting of cutting load as an example, cutting load parameter setting picture such as Fig. 3 institute
Show.
Delay time indicates the operating condition needs for meeting the criterion of action launching in power grid operating condition in cutting load judgement
Duration, this time needs and field device setting is consistent.If the setting time is too short, power grid more stable and
Load is cut off in the state of strong too early；If excision is too late, power grid be easy to cause low pressure and low frequency in the case where overload
Equal unsteady phenomenas.
The setting of starting and end time represents the intervention time section of the stabilization of power grids in effectual time, comprising steady
At the beginning of cutting off unit in devise a stratagem calculation, the end time, cut off the information such as rate.Peace control behavior simulation time started too early mistake
Evening, or the too fast correct emulation that all not can guarantee grid stability slowly excessively of excision rate, shape can be controlled with power grid actual motion
State has larger gap, to influence power grid control simulation accuracy.
Simulation result is as shown in Figure 4.A in Fig. 5 and B figure is respectively monopole receiving end in monopole sending end frequency diagram and day in day
Frequency diagram, ordinate are frequency, and unit is a hertz Hz, and abscissa is the time, and unit is a millisecond ms.It can be seen that straight in day
Stream monopole send end cutting machine when being latched in 200ms, receiving end cutting load changes, frequency in 200ms coordinate points mains frequency concussion trend
Curve B concussion trend is more obvious, becomes upward trend from low frequency downlink trend, and reach in subsequent concussion in 1800ms
Frequency stabilization.
The present invention also provides a kind of generations of power grid logic control script and result analogue system, as shown in figure 5, including
Script editor module, grid simulation module, parameter processing module and final script module；
Script editor module: for generating initial power grid logic control script file.It can by load electric network model file
To carry out electric network element selection, correlation combiner is carried out together with equipment working condition.According to grid operation mode and peace control policy depiction rule
Model carries out writing for associated script macrodefinition and logic control relation, and the sentence after combination is added in logical relation tree,
Final software can automatically generate the power grid logic control script file of reference format.
Grid simulation module: for writing from memory based on the power grid logic control script and in conjunction with the power grid logic control system
Recognize parameter to be emulated.Error detection and model checking carried out to script, and the result that will test and verify shown so as to
Modify, finally correct it is errorless after can carry out grid simulation.When grid simulation, power grid mould can be chosen individually or in bulk
It, can be to result of each data source after emulation after type file data or power flow files data and associated documents
It is presented respectively, and text can be carried out and save backup.
Parameter processing module: for handling power grid logic control system default parameters.By in parameter setting circle
Corresponding parameter is inputted or selected in face, is clicked and is generated grid configuration file after saving for using when emulation.The parameter of setting
Including cutting machine parameter and cutting load parameter.
