Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 1, an online checking and intelligent compiling method for a failure handling plan includes the following steps:
step 1: the method comprises the steps of obtaining an E-format electronic plan file of a general description language of the power system, realizing analysis and identification of plan contents by means of a plan electronic analysis module, obtaining key elements such as expected faults of the plan, an initial operation mode of a power grid, an operation mode and influence after the faults, fault handling measures, stability control requirements and the like, and storing the key elements in a database.
The key elements of the fault handling plan are as follows:
a) the expected faults are disturbances which are generated when a plan is used for dealing with a power grid, such as alternating-current and direct-current line faults, main transformer faults, bus faults, plant station full stop and the like;
b) the power grid initial operation mode mainly describes key operation characteristic information of a power grid before a fault occurs, and the key operation characteristic information comprises power generation and load levels, regional exchange power, system standby levels, key equipment operation states, key section or element tidal currents, safety automatic device states and the like;
c) the operation mode and the influence after the fault mainly describe the operation state of the power grid after the expected fault occurs, and the existing operation risk and influence, such as the problems of system frequency out-of-limit, power oscillation, section tidal current out-of-limit, equipment overload, bus voltage out-of-limit, accident disconnection, new energy off-grid, load loss and the like;
d) the stability control requirement is a constraint condition which is required to be met by the safe operation of the power grid after the expected fault occurs, such as section tidal current constraint, generator operation constraint, voltage and reactive power constraint, system standby constraint, safety automatic device strategy constraint and the like, and is mainly used for obtaining boundary conditions for subsequent calculation of specific adjustment quantity of treatment measures and auxiliary decision calculation;
e) the disposal measures are summary control means for solving various problems of the power grid, and include information such as disposal areas or adjusted equipment, adjustment sequences and the like, such as unit output adjustment, load adjustment, capacitive reactance device switching, equipment switching, direct current modulation and the like.
Step 2: and evaluating the adaptability of the initial operation mode of the pre-arranged power grid by comparing and analyzing the real-time mode data and the initial operation mode of the pre-arranged power grid based on the real-time operation mode data of the power grid and the initial operation mode of the power grid defined by the pre-arranged plan.
The adaptability evaluation of the initial operation mode of the pre-planned power grid is distinguished from the following aspects:
a) specific state quantities such as the running state of key equipment, the state of a safety automatic device and the like are judged whether to be strictly consistent or not;
b) judging whether the actual deviation amount is within a specified range or not according to tidal current values such as power generation and load levels, regional exchange power, system standby levels, key section or element tidal current levels and the like;
and if any judgment result does not meet the requirement, the initial operation mode of the pre-planned power grid is not suitable for the real-time operation mode data.
And step 3: and (4) performing safety and stability analysis on the planned expected faults on the real-time mode data, analyzing information such as primary frequency modulation characteristics, system protection strategies, safety control strategies and third line defense strategies of the power grid, which are accrued in the analysis, comparing the analysis result with the operation mode and influence after the planned faults, and evaluating the rationality of the operation mode and influence after the planned faults.
The rationality evaluation of the operation mode and the influence after the predetermined fault is judged from the following aspects:
a) whether the specific devices or areas affected by the fault are consistent;
b) whether the action conditions of the safety automatic device are consistent or not;
c) whether the running states of the power grid are consistent or not.
If any result is found, the operation mode and influence after the predetermined fault are unreasonable if the operation mode and influence after the predetermined fault cannot cover the data analysis result in the real-time mode.
And 4, step 4: and according to the severity and the handling stage of the safety and stability problem after the fault, checking the fault handling measures in stages, judging whether the fault handling measures can ensure the safe and stable operation of the power grid after the occurrence of the predetermined fault, and evaluating the rationality of the fault handling measures. The fault handling measures only give the conditions of the adjusting direction, such as which adjusting units or which stations but do not give specific adjusting amount of the units or stations, and then the specific adjusting amount of the handling measures is automatically calculated according to the sensitivity or the priority.
The rationality evaluation principle of the fault handling measures is as follows:
a) whether the given stability control requirement in the plan is met;
b) whether the abnormal operation state of the power grid is eliminated or not;
c) whether the grid operation meets the relevant standard specification requirements.
If any of the above conditions cannot meet the requirements, the fault handling measures are considered to be unreasonable.
And 5: and if the power grid can not safely and stably operate after the fault handling measures are executed or the fault handling measures are not given in the plan, performing auxiliary decision control measure calculation, and determining an auxiliary decision additional result meeting the power grid safe operation requirement, wherein the auxiliary decision additional result comprises control equipment and specific control quantity.
