Description

Technical Field

[0002] Currently, common power system time-domain simulation software such as PSD, ADPSS, PSCAD, RTDS, MATLAB, etc. all monitor the simulation progress and analyze the simulation data through the curves output by the components. In the case of a large number of curves stacked, the vision can only compare the change trends of each curve and has no ability to obtain the detailed information of each curve. Only by observing the curves one by one can detailed numerical analysis be carried out, thus consuming a lot of time.

[0003] It can be seen that the current power system digital simulation software only provides a data visualization analysis tool, which can only mobilize human vision for analysis. However, the human vision analysis ability is limited, and there is no room for further improving the simulation analysis efficiency in the visual dimension. Moreover, the simulation analysis takes a long time. Therefore, how to reduce the simulation analysis duration and improve the simulation analysis efficiency has become one of the current research focuses.

They are used together with the embodiments of the present invention to explain the present invention, and do not constitute a limitation to the present invention. In the drawings: Figure 1 is a flowchart of a method for realizing the sound effect playback of the running state of a time - domain simulation component for a power system in an embodiment of the present invention; Figure 2This is a schematic diagram of a simulation example built in a time-domain simulation software in an embodiment of the present invention for demonstrating the use and effects of sound effect components. Detailed implementation manners

[0018] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0019] An embodiment of the present invention provides a method for realizing sound effect playback of the operating state of a time-domain simulation component for a power system, as Figure 1 shown, including: Step 1: Design a target sound effect component and set parameters for the target sound effect component; Step 2: Real-time monitor the operating state of the target electrical component in the time-domain simulation, and process the obtained operating state data and transmit it to the corresponding target sound effect component; Step 3: The target sound effect component plays the corresponding sound effect according to the received data.

[0020] In this embodiment, the target sound effect component refers to a sound effect component that plays a sound effect related to the operating state by obtaining the operating state of the electrical component in the time-domain simulation. The target sound effect component has a built-in sound effect library, set parameters, and input pins. Among them, the input pins include Enable, Volume, and Speed; the target electrical component refers to an electrical component selected for sound effect playback feedback in the time-domain simulation of the power system, such as a circuit breaker, a transformer, etc.; the operating state data refers to various operating state data that the electrical component generates in real time during the simulation, such as current, voltage, power factor, etc. After being processed, the data is transmitted to the target sound effect component through a pre-set communication protocol and interface.

[0021] In this embodiment, for example, a simulation example built in a certain time-domain simulation software for demonstrating the use and effects of sound effect components, as Figure 2 shown.

[0022] The beneficial effects of the above technical solution are: by designing the target sound effect component, real-time monitoring the operating state of the target electrical component in the time-domain simulation, and processing the obtained operating state data and transmitting it to the corresponding target sound effect component; the target sound effect component plays the corresponding sound effect according to the received data, which can realize the intuitive perception of the operating state of the power system, help reduce the number of simulation analysis times, and thus improve the simulation analysis efficiency.

[0023] An embodiment of the present invention provides a method for realizing sound effect playback of the operating state of a time-domain simulation component for a power system. Design a target sound effect component and set parameters for the target sound effect component, including: For the target sound effect component, an internal sound effect library is provided. The sound effect library is used to store preset audio files of electrical equipment and supports users to upload and store self-made audio files; Two setting parameters, namely the sound effect file and the playback mode, are deployed for the target sound effect component. The sound effect file is used to select an audio from the built-in audio files or user-uploaded audio files, and the playback mode is used to select a mode from two playback modes: loop playback and single playback; Three input pins, namely Enable, Volume, and Speed, are designed for the target sound effect component.

[0024] In this embodiment, the preset electrical equipment refers to electrical equipment with sound, including equipment such as motors, transformers, circuit breakers, and converters; The Enable input pin is used to control the playback and stop of the sound effect, and only receives two numbers, 0 and 1. When receiving 1, the sound effect starts to play, and when receiving 0, the sound effect stops playing; The Volume input pin is used to control the volume of the sound effect and receives any digital quantity between 0 and 1. 1 is the maximum volume, and 0 is the minimum volume; The Speed input pin is used to control the playback speed of the sound effect and receives any digital quantity greater than 0. Among them, 1 represents the normal playback speed, less than 1 represents decelerated playback, and greater than 1 represents accelerated playback.

[0025] The beneficial effects of the above technical solutions are: By designing the target sound effect component and setting parameters, the personalization and practicality of the simulation can be further enhanced, providing effective support for realizing the sound effect feedback of the operation state of the power system.

[0026] An embodiment of the present invention provides a method for realizing the sound effect playback of the operation state of a time-domain simulation component in a power system, which real-time monitors the operation state of a target electrical component in the time-domain simulation and transmits the obtained operation state data to the corresponding target sound effect component after processing, including: Real-time monitor the operation state of the target electrical component in the time-domain simulation to obtain the first operation state data; Obtain the set sound effect logic-data list and the set target sound effect component list according to the component type of the current target electrical component; According to the component number of the current target electrical component, obtain the corresponding first target sound effect component and the corresponding key setting parameters from the set target sound effect component list; Use the key setting parameters to set the setting parameters of the first target sound effect component; Use the set sound effect logic-data list to divide the first operation state data to obtain the logic-state data under different sound effect playback logics; Process the obtained logic-state data according to the set data processing scheme of the corresponding sound effect playback logic to obtain the key logic data under different sound effect playback logics; Pin-label the key logic data to the input pins corresponding to the associated sound effect playback logic. Input the key logic data into the corresponding input pins of the first target sound effect component that is consistent with the labeled pins.

[0027] In this embodiment, the first operating state data refers to the real-time operating data of the target electrical component monitored in real time during time-domain simulation, such as current, voltage, power factor, etc.; the component type refers to the classification of the target electrical component in the power system, such as load, transformer, circuit breaker; the set sound effect logic-data list is composed of the preset sound effect playback logic and the corresponding associated operating state data. Among them, the sound effect playback logic includes the Enable pin logic (the associated operating state data includes the opening and closing of the circuit breaker, voltage change, etc.), the Volume pin logic (the associated operating state data includes load current, etc.), and the Speed pin logic (the associated operating state data includes grid frequency, etc.).

[0028] In this embodiment, the set target sound effect component list refers to the preset list of target sound effect components associated with each component type; the key setting parameters refer to the configuration of the setting parameters of the first target sound effect component; the logic-state data refers to the data obtained by dividing the first operating state data according to the sound effect playback logic; the set data processing scheme refers to the preset data processing flow for each sound effect playback logic. For example, the operating state data associated with the Enable pin logic generates a pulse signal that lasts for a certain period of time through a logic circuit (such as an edge detector, a monostable flip-flop, etc.); the operating state data associated with the Volume pin logic (such as load current) is converted into a digital quantity between 0 and 1; the operating state data associated with the Speed pin logic (such as grid frequency) is converted into a digital quantity greater than 0; the key logic data refers to the data that matches a specific sound effect playback logic after being processed by the set data processing scheme, and is used to trigger the sound effect component to play the corresponding sound effect.

[0029] In this embodiment, for example, there is a sound effect component 1 for playing the sound effect of the circuit breaker. The playback mode is set to single playback. The sound effect file is selected as "circuit breaker sound effect". The Speed pin and the Volume pin input the constant 1, indicating that the sound effect is played at the normal speed and the maximum volume. The Enable pin receives a signal related to the states of the three phases A, B, and C of the circuit breaker, so that any phase state change causes the Enable to receive a pulse signal lasting for 0.5 s. (Logical explanation: BRK_status is the states of the three phases A, B, and C of the circuit breaker, outputting 1 when closed and 0 when open. The edge detector outputs a spike pulse with an amplitude of 1 when detecting a transition from 0 to 1 or from 1 to 0. The monostable flip-flop converts the narrow pulse into a wide pulse lasting for 0.5 s. The three monostable flip-flops are input to the Enable pin through an OR gate, achieving the effect that any phase state change of the three phases A, B, and C starts the sound effect component 1.) There is a sound effect component 2 for playing the sound effect of the transformer. The playback mode is set to repeat playback (this can ensure continuous playback when the simulation time is greater than the sound effect file time). The sound effect file is selected as "transformer sound effect". The Volume pin inputs the constant 1, indicating that the sound effect is played at the maximum volume; the Speed pin inputs a signal related to the power grid frequency. When the frequency is 50 Hz, the sound effect is played at the normal speed, but when the frequency deviates from 50 Hz, the playback speed also deviates from 1, so that the change of the system frequency can be distinguished from the sound effect; the Enable pin receives a signal related to the voltage. When the voltage is higher than 0.3, the sound effect component 2 is started to simulate the operating sound effect after the transformer is energized. (Logical explanation: The output signal VT of the voltmeter is the three-phase voltage at the access point. The PLL can measure the frequency from the three-phase voltage VT.) There is a sound effect component 3 for playing the sound effect of the load. The playback mode is set to repeat playback (this can ensure continuous playback of the sound effect when the simulation time is greater than the sound effect file time). The sound effect file is selected as "load sound effect". The Volume pin inputs the constant 1, indicating that the sound effect is played at the maximum volume; the Speed pin inputs the constant 1, indicating that the sound effect is played at the normal speed; the Volume pin inputs a signal related to the load current. The rated load current is 0.577 kA, and IL_rms is the current measured from the load component. When the load current changes, the volume of the sound effect component 3 also changes accordingly, so that the magnitude of the load current can be distinguished from the sound effect; the Enable pin is connected to the Enable pin of the transformer sound effect component because the load will be energized after the transformer is energized.

[0030] The beneficial effects of the above technical solutions are as follows: By real-time monitoring the operating states of various target electrical components in the time-domain simulation and transmitting the obtained operating state data to the corresponding target sound effect components after processing, the operating states of the electrical components can be intuitively reflected, improving the intuitiveness and interactivity of the simulation.

[0032] In this embodiment, the set of state threshold lists refers to a series of preset operating state threshold ranges for each type of target electrical component, and the operating state threshold ranges are used to determine whether the operating state of the electrical component is normal; abnormal state data refers to the first operating state data that does not belong to the corresponding operating state threshold range; the state abnormality coefficient is used to characterize the degree of state abnormality of the current target electrical component; the state abnormality level is obtained from a set abnormal level table with the state abnormality coefficient as the matching condition, where the set abnormal level table consists of an abnormal coefficient value range and the corresponding abnormal levels, and the abnormal levels include three levels: slight abnormality, normal abnormality, and special abnormality; the abnormal-setting parameters are a combination of the sound effect file and playback mode matched from the preset abnormal setting mapping table according to the state abnormality level and the component type.

[0033] The beneficial effects of the above technical solution are: By comparing the operating state data with the set of state threshold lists, abnormal state data can be accurately identified, thus timely issuing a fault warning; According to the state abnormality coefficient and the component type, intelligently adjusting the sound effect file and playback mode of the target sound effect component can make the sound effect feedback more in line with the actual operating state of the electrical component, improving the fault warning ability of the simulation system.

[0034] An embodiment of the present invention provides a method for realizing sound effect playback of the operating state of a time-domain simulation component in a power system, and the calculation formula of the state abnormality coefficient is as follows: ; where, represents the state abnormality coefficient of the current target electrical component; It represents the upper limit of the corresponding operating state threshold for the i-th abnormal state data of the current target electrical component, where i = 1, 2, 3, , n; n represents the total number of abnormal state data of the current target electrical component; It represents the value of the i-th abnormal state data of the target electrical component at the current time t; It represents the lower limit of the corresponding operating state threshold for the i-th abnormal state data of the current target electrical component; It represents the contribution weight of the i-th abnormal state data of the current target electrical component to the operation of the component; e represents a constant with a value of 2.7; It represents the value of the i-th abnormal state data of the current target electrical component at the time t - 1; It represents the value of the i-th abnormal state data of the current target electrical component at the time t - 2; It represents the value of the i-th abnormal state data of the current target electrical component at the time t - 3.

[0035] In this embodiment, the weights assigned to different abnormal state data are obtained by solving the matrix constructed after pairwise comparison and relative importance scoring using the analytic hierarchy process.

[0036] The beneficial effects of the above technical solution are: By calculating the state anomaly coefficient, it can provide a data basis for obtaining the anomaly level of the target electrical component, and then realize the intelligent adjustment of the sound effect file and playback mode of the corresponding first target sound effect component of the target electrical component.

[0039] In this embodiment, the second adjustment element refers to the target electrical component with a priority lower than the reference priority in the volume - priority list; the second level difference refers to the difference between the priority of the second adjustment element and the reference priority.

[0040] In this embodiment, for example, there is a first adjustment element r1 with a priority of level 6, a second adjustment element r2 with a priority of level 2, and the current reference priority is level 4; at this time, the first level difference b1 is +2 levels, and the second level difference b2 is -2 levels; The volume of the sound effect played corresponding to the first adjustment element r1 is increased based on the first level difference, and the calculation formula for the first adjusted volume is expressed as ; in the formula, represents the first adjusted volume of the sound effect played corresponding to the first adjustment element r1; represents the volume before adjustment of the sound effect played corresponding to the first adjustment element r1; represents the total number of priorities of the target electrical components; represents the first level difference; ln represents the natural logarithm; e represents a constant with a value of 2.7; The volume of the sound effect played corresponding to the second adjustment element r2 is increased based on the second level difference, and the calculation formula for the second adjusted volume is expressed as ; in the formula, h represents the first adjusted volume of the sound effect played corresponding to the second adjustment element r2; h represents the volume before adjustment of the sound effect played corresponding to the second adjustment element r2; It is expressed as the second level difference.
