Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments 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.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
First, the meaning of some terms related to the present invention is described:
testing a section: the test profile refers to a set of all possible operation processes and occurrence probabilities thereof under the combined action of a plurality of operators and participants. The method can reflect the possible branch processes and operation probability of the application under the common action of a plurality of operators or participants, and the influence and change generated by the interaction behavior of the application with other applications in the system under the condition of the functional requirement. The operating profile is the definition of the conditions of use of the system. I.e. the input values of the system are defined by their distribution over time or by their distribution of probability of occurrence over the range of possible inputs.
Scene: a scenario refers to a set of sequences of actions that a system implements a complete functional requirement specification, describing the interaction between a user, system components, and the environment to achieve a certain goal.
The invention is described in further detail below with reference to the accompanying drawings:
currently, the conventional test profile construction method for applying reliability test is generally the Musa operation profile. The construction method of the Musa operating profile is divided into two.
In the first method, the main use customers of the application product are firstly determined, and the probability of each customer is determined; secondly, determining the user type and the occurrence probability of each client; thirdly, defining a system operation mode and the occurrence probability of the system in the using process of each user; fourthly, determining the main function operation and the use probability of the system in each mode; and fifthly, fusing the information obtained in the previous four steps to determine the complete operation section of the whole application object. In the second method, the operating mode of the system is first determined, which is the same concept as the system mode in the first method of Musa, is a unique mode used by the system, and is a collection of environmental conditions that need to be tested separately. The second step determines the initiator of the operation, including the user of the system, the external systems and the control programs of the system itself. And selecting a representation method of the operation section, wherein the operation section can be represented by a table representation method or a graphic representation method. And fourthly, determining an operation list of each operation initiator based on each operation initiator, and determining each obviously different process as a different operation. Fifth, the occurrence rate of each operation is determined, the occurrence rate being the number of occurrences of the operation or attribute value per unit time, the occurrence rate preferably being determined using actual data. Such a measure of usage is often available from a log of the system. And sixthly, determining the occurrence probability of the operation, wherein the occurrence probability of the operation or the attribute value is calculated by the occurrence rate and can be obtained by dividing the occurrence frequency of the operation/attribute value by the total occurrence number of all the operation/attribute values.
However, the power grid dispatching application does not have obvious operation, has the main characteristics of system interactivity, environmental influence, activity time sequence and the like in the running process, and has special technical requirements when the application reliability test section structure is carried out on the power grid dispatching application.
Wherein, the system interactivity: for the interactivity of the application, on one hand, during the running process of the application, not only the operation process of a single operator is influenced, but also a running process of a certain activity of the application and a branch condition and a subsequent influence which may be generated by the running process may be jointly decided by a plurality of operation initiators or participants. On the other hand, the activity process of a certain application is not determined by the application itself, but in a real-time system where a certain function requirement is completed together, the interaction process of multiple applications may determine the respective possible operation process of each application together. Environmental impact: for the application, the application is often influenced by factors such as temperature, pressure, humidity and the like of the external environment of the system where the application is located in the operation process; when the system is applied to different operation modes, the system can enter different operation environments to form an operation process with a feedback loop. For the application of the dispatching automation master station system, various input circuit indexes of the dispatching automation master station system have different change rules along with different environmental seasons and different times of the day. Activity timing sequence: in the operation process, a certain operation process is not only a simple series relation of operation sequences, but also a limiting condition of a time factor. Different running processes may be generated under different time intervals between the application operations. Taking the application of the dispatching automation master station system as an example, due to the characteristic of long-time running monitoring, the complexity of activity timeliness is mainly reflected in the automatic data receiving and sending and automatic data processing processes and the manual operation which may be needed.
Therefore, the existing construction method of the Musa operation profile does not have all the factors described in the technical requirements, and cannot be applied to test profile modeling of power grid dispatching application.
Based on the above, referring to fig. 1, in an embodiment of the present invention, a method for modeling a test profile of a power grid dispatching application is provided, in which a modeling process of a power grid system scenario is added to a characteristic of the power grid dispatching application, and modeling is performed from two perspectives of the power grid system scenario and an application scenario by using extracted system characteristics, that is, a plurality of elements that affect the operation of the power grid dispatching application, so as to jointly form a test profile for an application reliability test. Specifically, the test profile modeling method for the power grid dispatching application comprises the following steps:
s1: and acquiring a plurality of elements influencing the operation of the power grid dispatching application and the service logic relationship of the power grid dispatching application.
Specifically, before modeling a test profile of a power grid dispatching application, a set of elements affecting the operation of the power grid system needs to be analyzed on the basis of the outside of the power grid system, and preferably, the elements include user classifications, different operation modes, different operation environments, different use conditions and the like.
When the test profile modeling of the power grid dispatching application is performed, a plurality of elements in a preset element set and a service logic relationship of the power grid dispatching application need to be obtained, wherein the service logic relationship of the power grid dispatching application is necessary content when the power grid dispatching application is constructed, and corresponding information can be obtained from a management system of the power grid dispatching application. Based on the service logic relationship of the power grid dispatching application, each element can be a condition relationship or an independent relationship, and a plurality of combinations can be divided according to the closeness degree of the relationship between the elements.
S2: obtaining an incidence relation among a plurality of elements according to a service logic relation of power grid dispatching application, and constructing a plurality of power grid system scenes according to the incidence relation among the plurality of elements.
Specifically, the association relationship between the plurality of elements is obtained according to the service logic relationship of the power grid dispatching application, for example, the power grid dispatching application includes different operation modes and different use conditions under different user classifications, and if the administrator has more application permissions than the users.
Referring to fig. 2, in the embodiment, a real-time monitoring and control (SCADA) system in an intelligent power grid dispatching control system is taken as an example to establish a power grid system scene. The SCADA system has three types of users, wherein a bidirectional relationship is established between a dispatcher, an operator and the SCADA system, namely the SCADA system provides information for the users, and the users have control authority over the SCADA system; the operation and maintenance personnel and the SCADA system have a one-way relationship and are responsible for operating and maintaining the SCADA system.
Referring to fig. 3, which represents a power grid system scenario modeling process for different operating modes of a power grid system, the SCADA system can be described as three usage modes, namely a switch module usage mode, a telemetry signal control module usage mode, and a disconnecting link module usage mode. From the perspective of different users, different types of users have different purposes for the use of the application, such as dispatchers and operators may be more concerned about the switch module usage pattern and the telemetry signal control module usage pattern, since they need to receive monitoring information and alarm information from the SCADA system.
Preferably, the power grid system scene includes one or more of a power grid use scene, a power grid operation continuous scene and a power grid operation concurrent scene.
The continuous power grid operation scene is used for describing the situation that some input variable changes continuously in the manual power grid operation, and can also be understood as the continuous operation of a power grid use scene, and the description of each variable in the continuous power grid operation scene is composed of coordinates of which the horizontal axis is time and the vertical axis is value size (Boolean type, floating point type, integer type) or character string (enumeration type). The power grid operation concurrency scene is used for representing the starting time and duration of power grid manual operation and the description mode of concurrency operation in the application running state, and can also be understood as continuous running of a plurality of power grid use scenes for representing the concurrency relation among the internal power grid use scenes. The manual operation of the power grid comprises each use mode, each function and each operation of the power grid dispatching application.
S3: in each power grid system scene, all usage modes contained in the power grid dispatching application, all functions contained in each usage mode, incidence relations among the functions, all operations contained in each function and operation flows of each operation are obtained according to the service logic relations of the power grid dispatching application, and the logic relations of the power grid system scenes are obtained.
Specifically, in each grid system scenario, how the grid system is used is described by modeling, taking into account the uses that can be implemented at the level of the grid system scenario, and the relationship between each use, which represents the use of the grid scheduling application by the user in a specific range, which is essentially a dynamic simulation of the use of the user. Firstly, all the use modes contained in the power grid dispatching application are obtained and used as a layer of structure, then all the functions contained in each use mode and the incidence relation among the functions are obtained and used as a next layer of structure, and finally all the operations contained in each function and the operation flow of each operation are obtained and used as a bottom layer structure, and the logical relation of a power grid system scene of a layered nested structure is formed.
In this embodiment, referring to fig. 4, a switch module usage mode of the SCADA system is taken as an example, and a logical relationship of a power grid system scene is constructed for the switch module usage mode. For the use mode of the switch module in the SCADA, the main functions of the switch module include setting a signboard, remote control inspection, remote control, preposition information, remote control test, alarm suppression/recovery, remote signaling blocking/releasing, point information refreshing, remote signaling contraposition, station remote signaling contraposition, interval remote signaling contraposition and the like, wherein a next-level nested structure is established for the functions of setting the signboard, the remote control inspection, the remote control, the preposition information and the like. Referring to fig. 5, taking the telemetry control function as an example, the main workflow is to perform login operation at an input window after a user selects a remote control reason and a monitoring type, perform remote control presetting and remote control execution operation after correct login, and cancel existing telemetry control with a certain probability in the execution process.
S4: and under each power grid system scene, according to the logical relation of the power grid system scene, combining the execution probability and the constraint condition preset by each use mode, the execution probability and the constraint condition preset by each function and the execution probability and the constraint condition preset by each operation to obtain a power grid system scene profile.
After establishing the logical relationship of the grid system scenarios, the probability of possible use, i.e. the execution probability, of each usage pattern, each function and each operation needs to be assigned, which is the possibility of using other or own grid manual operations after one grid manual operation, and is a relative probability.
In this embodiment, the execution probability of each usage pattern, the execution probability of each function, and the execution probability of each operation are set in advance. Preferably, the execution probability of each usage pattern, the execution probability of each function, and the execution probability of each operation are obtained by statistics according to historical data of the same or similar applications, or by statistics according to user research data. Specifically, the execution probability of each usage pattern includes a probability of directly executing the usage pattern, and an execution probability of continuing to execute the usage pattern after executing a higher-level usage pattern associated with the usage pattern. Similarly, the execution probability of each function and the execution probability of each operation respectively include the probability of directly executing the function or operation and the probability of continuing to execute the function or operation after executing the function or operation associated therewith. And, starting from one grid manual operation, the sum of the execution probabilities of all the grid manual operations which can be executed continuously is equal to 1.
After the logical relationship of the power grid system scenarios of each power grid system scenario is established, the constraint conditions of each usage mode, each function and each operation also need to be set. Specifically, the constraint condition is set based on a business logic relationship of the power grid dispatching application, and the implementation of each use mode, each function and each operation needs to be limited to prevent the application from running indefinitely. The constraint is another use determinant of grid manual operation, which is usually reflected in a precondition in grid manual operation. The source of the constraint condition may be the value of the previous input variable, time, or the output value of the tested system whose value is unknown.
Referring to fig. 6, in the present embodiment, taking an alarm suppression/recovery operation in the telemetry control function in the SCADA system as an example, in the alarm suppression/recovery operation, a user may initially click an alarm suppression button and an interval alarm suppression button. When the selected telemetering value is in the alarm suppression state, the user can select to click the alarm recovery button, when the selected telemetering value is in the interval alarm suppression state, the user can select the alarm recovery of the single telemetering value in the interval or the interval alarm recovery of the full interval, and if the alarm recovery of the single telemetering value is selected, the user can still continue to select the next alarm recovery button and the interval alarm recovery button until all the alarm suppression signals in the interval are reset.
And embedding the execution probability and the constraint condition preset by each use mode, the execution probability and the constraint condition preset by each function and the execution probability and the constraint condition preset by each operation into the logic relation of the power grid system scene to obtain the power grid system scene profile.
