Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power quality treatment, and in particular to a power quality treatment application verification method, device, equipment and storage medium. BACKGROUND

[0002] With the rapid development of new energy technology and power electronics technology, a large number of distributed power sources and power electronic devices are connected to the distribution area, which reduces the inertia of the distribution area system and increases the uncertainty, seriously affecting the power quality of the distribution area. In order to ensure the safe and stable operation of the new distribution area, a reliable power quality treatment method is particularly important.

[0003] Common power quality problems in distribution networks include voltage fluctuation, low voltage at the end, three-phase imbalance, harmonic pollution, etc. There are many treatment devices and methods for common power quality problems in distribution networks at present, but there is a lack of mature power quality treatment application verification method, which cannot effectively test and verify the application effect of related devices and methods before actual network operation, which is not conducive to the improvement of the power quality of the distribution area and the stable operation of the distribution area. Especially in the new intelligent distribution network, the structure and function of the distribution network are more complex, and various new types of power equipment have higher requirements for power quality.

[0004] However, the existing technical scheme for power quality treatment application verification provides a test environment required for power quality treatment application verification by constructing a simplified distribution network model and simulating power quality interference of the distribution network, which has the following disadvantages: 1) in terms of reliability of test results, since the distribution network model constructed by the existing technical scheme is simulated for traditional distribution networks, it does not have key elements such as distributed power sources and AC / DC charging piles in new intelligent distribution networks, and it is also unable to construct typical scenarios of distribution Internet of Things, making it difficult to truly simulate the operating characteristics of the current actual distribution network, and the reliability of the test results cannot be guaranteed; 2) in terms of richness of test scenarios, due to the limitation of platform elements, the existing technical scheme is difficult to reliably simulate scenarios for power quality treatment applications such as three-phase imbalance of the distribution area and voltage drop at the end; 3) in terms of test convenience and ease of use, the existing technical scheme does not design the specific test processes such as test scenario arrangement, data collection and result analysis in a standardized manner, and the test efficiency is low. Therefore, a reliable power quality treatment application verification platform and method are urgently needed to effectively improve the power quality level of the distribution area. SUMMARY

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0070] Example 1

[0071] Please refer to Figure 1 The present invention provides a power quality management application verification method, which is implemented through a transparent transformer substation real-model platform, and includes the following steps S101-S104:

[0072] Step S101: Based on the test requirements and in conjunction with the transparent transformer substation model platform, edit and generate a test plan; wherein, the test plan includes: the treatment equipment to be tested or the treatment method to be evaluated, and the transparent transformer substation model platform is used to provide verification scenarios for several types of power quality treatment functions.

[0073] In this embodiment, the test plan is used to guide the overall test process, such as... Figure 2 As shown, the real-world platform management system has a typical case editing function, which can edit and preset typical test plans. The specific test plan content includes: test requirements analysis, test topology determination, test parameter determination, test detection data determination, and test result analysis.

[0074] As a preferred embodiment, the transparent distribution area real-world platform includes: traditional distribution area key equipment, new distribution area equipment, a power quality management area for accessing power quality management equipment through standardized interfaces, and a smart gateway for IoT networking of smart switches and smart sensing terminals within the distribution area.

[0075] It should be noted that the transparent distribution area simulation platform can realistically simulate the operating characteristics of new distribution areas with a high proportion of distributed power sources and power electronic equipment access. It can also set up typical test scenarios and connect the devices under test for different power quality problems, realizing diversified power quality governance scenario simulation. This supports the functional verification of power quality governance equipment and methods in distribution areas under the background of new power systems, and improves the power quality level of distribution areas.

[0076] In this embodiment, the transparent platform is a true-to-life model. Figure 3 As shown, this platform is used to simulate the operational characteristics of new distribution transformer substations, providing a verification environment for power quality management applications that conforms to actual field conditions. The transparent substation simulation platform includes key equipment from traditional distribution transformer substations such as distribution transformers, integrated distribution boxes (JP cabinets), branch boxes, household meter boxes, and user equipment; it also features characteristic elements of new distribution transformer substations such as distributed simulated power supplies and simulated charging piles, simulating typical operational scenarios of new distribution transformer substations; simultaneously, the simulation platform is configured with a power quality management area, providing standardized interfaces for actual connection of power quality management equipment such as smart capacitors, active power filters, and static var generators.

[0077] It should be noted that the low-voltage simulation platform is configured with intelligent gateways and various sensing devices for IoT networking in the distribution area. The intelligent gateway is an IoT edge computing terminal applied to the low-voltage intelligent distribution area, integrating functions such as distribution area power supply information collection, equipment status monitoring and communication networking, local analysis and decision-making, and master station communication.

[0078] In this embodiment, the terminal adopts a platform-based hardware design and edge computing architecture, supporting local data storage and decision analysis. The data transmission stream of the smart gateway is as follows: Figure 4 As shown, the gateway uses the MQTT protocol as the data bus. Various monitoring data in the distribution area are accessed by the smart gateway through different protocols and then distributed to different apps for edge computing or storage via the MQTT bus. The smart gateway interacts with the Internet of Things (IoT) platform through the MQTT protocol, receives instructions from the IoT platform and sends the monitoring data information of the distribution area. In this invention, the IoT platform function is implemented by the real-model platform test management system.

[0079] In this embodiment, the smart gateway serves as the core, enabling the Internet of Things (IoT) networking of smart switches and smart sensing terminals within the distribution area to construct a system as follows: Figure 5 The illustrated intelligent monitoring system for the full-scale platform can realize real-time monitoring of various data such as electrical protection and control of the distribution area, environmental monitoring, video surveillance, and security alarms, creating a transparent full-scale test platform with panoramic status awareness. In the power quality management application verification technology solution proposed in the invention, the data of the entire test process can be collected and displayed in real time through the distribution network Internet of Things, intuitively demonstrating the test results.

[0081] In this embodiment, the test parameter settings are based on the one-key generated test scheme, and the specific test parameter settings include platform parameter settings and scene parameter settings. The platform parameter settings are based on the topology model in the test scheme to configure the true model platform grid, construct a true model platform test topology grid that meets the test requirements, and complete the access and initialization of the corresponding equipment. The scene parameter settings are used to set the platform equipment parameters and access and set the to-be-tested equipment parameters to realize different power quality abnormal operation condition simulation and to-be-tested equipment network operation. The specific parameter setting contents are the contents determined in the "test parameter determination" in step S1.

[0082] Step S103: Test the Internet of Things platform constructed by the intelligent gateway, each intelligent switch and intelligent sensing terminal in the transparent substation true model platform after the parameter settings, and monitor the test data during the test to obtain terminal sensing data.

[0083] In this embodiment, the test data online monitoring can be realized through the power distribution Internet of Things constructed with the intelligent gateway as the core. The intelligent sensing terminals and power quality analyzers in the true model platform sense the key equipment states and key node parameters in the test process in real time and collect them to the intelligent gateway. The intelligent gateway directly forwards or forwards after edge computing the collected terminal sensing data to the Internet of Things platform for data display and advanced application analysis.

[0084] Step S104: Analyze and evaluate the test results of the to-be-tested treatment equipment or to-be-evaluated treatment method according to the terminal sensing data through the Internet of Things platform, and generate a test analysis report.

[0085] In this embodiment, the Internet of Things platform automatically analyzes and evaluates the test results of the to-be-tested treatment equipment or to-be-evaluated treatment method according to the test process state sensing data, and automatically generates a test analysis report.

[0086] The implementation of the above embodiments has the following effects:

[0087] The technical scheme of the present application can accurately and reliably build a platform for simulation running by editing the test scheme and setting parameters of the transparent transformer area real platform and verifying the scene parameters, so as to have the new intelligent power distribution system simulation running capability, support various power quality treatment application function verification under the background of new power system, build the Internet of Things to realize platform state panoramic perception and transparent test process display, intuitively display the test effect, accurately and reliably collect and acquire the simulated data, provide a systematic real test environment, the test result has high reliability, finally analyze the test result, improve the test efficiency and easy operation, and based on the terminal perception data collected by the Internet of Things platform, automatically perform hierarchical analysis, improve the accuracy and efficiency of power quality analysis, and improve the operation experience of users in power quality analysis and detection.

[0089] The present embodiment provides preferred embodiments of each step (including steps S101-S104) in embodiment one.

[0090] As a preferred scheme of the present embodiment, the test scheme is edited and generated according to the test requirements and in combination with the transparent transformer area real platform, specifically including:

[0091] The test requirements are analyzed to determine the type of power quality problem to be simulated, and the test type is obtained; based on the test requirements and the configuration of the transparent transformer area real platform, test topology modeling is performed to confirm the source-load equipment and data acquisition equipment to be input in the test topology; based on the test requirements, the degree of power quality abnormality to be simulated for the test is determined, and the test data to be monitored is determined; according to the degree of power quality abnormality and the test data to be monitored, a typical verification scene is edited, and a test result analysis process is set, so as to plan the test implementation process in combination with the typical verification scene, determine the test execution steps; the test type and the corresponding edited test topology, test data to be monitored, typical verification scene and test execution steps are pre-stored as a typical implementation case, as the edited and generated test scheme.

The evaluation basis is the key data collected in the test data acquisition step.

[0094] As a preferred scheme of the embodiment, the parameter setting of the transparent distribution area real platform and the parameter setting of the verification scene according to the test scheme specifically include:

[0095] According to the platform network configuration of the test topology in the test scheme, a real platform test topology network frame meeting the test demand is constructed, and the to-be-tested treatment equipment is accessed and initialized, so that the parameter setting of the transparent distribution area real platform is completed; according to the source-load equipment and data acquisition equipment to be input in the test topology in the test scheme and the to-be-monitored test data, the parameter setting of the verification scene is performed in combination with the to-be-tested treatment equipment accessed and initialized, and the to-be-tested treatment equipment is operated together with different power quality abnormal operating condition simulation.

[0096] In the embodiment, the test parameter setting is based on the one-key generated test scheme, and specific test parameter setting is performed, including platform parameter setting and scene parameter setting. The platform parameter setting configures the true platform network frame according to the topology model in the test scheme, constructs a true platform test topology network frame meeting the test requirements, and completes the access and initialization of the corresponding equipment; the scene parameter setting is used for platform equipment parameter setting and the access and parameter setting of the to-be-tested equipment, so as to realize different power quality abnormal operation condition simulation and the online operation of the to-be-tested equipment.

[0097] In the embodiment, the specific parameter setting content is the content determined in the "test parameter determination" in step S1 of the embodiment. The source-load equipment, data acquisition equipment and test data to be monitored required by the test topology in the test scheme are combined with the to-be-tested treatment equipment after access and initialization, the parameters of the corresponding verification scene are set, and the accuracy of the simulation simulation scene is improved.

[0098] As a preferred scheme of the embodiment, the Internet of Things platform constructed by the intelligent gateway, the intelligent switch and the intelligent sensing terminal in the parameter-set transparent substation true platform is tested, and test data monitoring is performed during the test to obtain terminal sensing data, specifically including:

[0099] The to-be-tested treatment equipment accessed and initialized after parameter setting is connected and accessed to each corresponding intelligent switch, and each intelligent switch connected and accessed is set with a corresponding intelligent gateway, so as to construct an Internet of Things platform; after constructing the Internet of Things platform, based on the test scheme and different power quality abnormal operation condition simulation of the to-be-tested treatment equipment respectively, the power treatment test of the transparent substation true platform is performed; wherein, the power treatment test includes the power quality abnormal operation condition simulation stage and the treatment stage; based on the intelligent sensing terminal in the Internet of Things platform and the power quality analyzer, test data monitoring is performed during the test, so as to collect key equipment states and key node parameters in real time as terminal sensing data and then collect the terminal sensing data to the intelligent gateway; wherein, the terminal sensing data includes abnormal stage data, treatment stage data and post-treatment data; the terminal sensing data collected to the intelligent gateway is directly forwarded or forwarded to the Internet of Things platform after edge computing, so as to perform data display and advanced application analysis.

[0100] In this embodiment, the test data online monitoring can be realized by the power distribution Internet of Things constructed with the intelligent gateway as the core. The various types of intelligent sensing terminals in the real platform and the power quality analyzers sense the key equipment states and key node parameters in the test process in real time and then collect them to the intelligent gateway. The intelligent gateway directly forwards or forwards after edge computing the terminal sensing data to the Internet of Things platform for data display and advanced application analysis.

[0101] In this embodiment, the to-be-tested governance equipment as the intelligent sensing terminal needs to be connected to the system after parameter setting. These devices will be connected with the corresponding intelligent switches respectively to realize data collection and control signal transmission. After the intelligent switches are connected with the intelligent sensing terminals, the corresponding intelligent gateways need to be set for these connections. The intelligent gateway as the key equipment for data collection, transmission and processing is responsible for collecting and preliminarily processing the data of the front-end equipment. Thus, an Internet of Things platform can be constructed, which integrates functions such as device access, data transmission, data processing and application services. This platform will support the connection of a large number of devices and provide data services such as data access, analysis, storage and analysis. Based on the test scheme, different power quality abnormal operating conditions will be simulated to test the performance of the to-be-tested governance equipment. This includes the simulation of power quality indexes such as voltage deviation, frequency deviation, harmonic, three-phase voltage unbalance degree, etc. The power governance test includes the simulation stage of power quality abnormal operating conditions and the governance stage. In the simulation stage, we will simulate various abnormal conditions in the power grid; in the governance stage, the to-be-tested governance equipment will try to compensate and adjust these abnormalities. In the test process, the intelligent sensing terminals and the power quality analyzers will monitor and collect the key equipment states and key node parameters in real time. These data will be used as terminal sensing data, including abnormal stage data, governance stage data and post-governance data. The terminal sensing data will be collected to the intelligent gateway, and then directly forwarded or forwarded after edge computing to the Internet of Things platform. Edge computing can process data near the data source, reduce delay and improve response speed. On the Internet of Things platform, the collected data will be used for data display and advanced application analysis, including evaluation of the effect of power governance, monitoring of equipment performance and formulation of optimization strategies and other extended functions.

[0102] As a preferred scheme of this embodiment, the analysis and evaluation of the test results of the to-be-tested governance equipment or the to-be-evaluated governance method according to the terminal sensing data through the Internet of Things platform and the generation of the test analysis report specifically include:

[0103] By the Internet of Things platform, the actual scene is parsed according to the collected terminal perception data; the actual scene is verified and compared with the verification scene, when the actual scene is consistent with the verification scene, the abnormal stage data in the terminal perception data is analyzed, the corresponding actual abnormal working condition is obtained, and the actual perception device is judged; if the actual perception device corresponds to the to-be-tested management device, and the actual abnormal working condition of the actual perception device is the same as the power quality abnormal operation working condition corresponding to the to-be-tested management device, the management stage data and the post-management data in the terminal perception data are analyzed, and according to a preset evaluation model, the management stage data and the post-management data are automatically analyzed, so as to automatically generate a test analysis report.

[0104] In this embodiment, the Internet of Things platform automatically analyzes and evaluates the test results of the to-be-tested management device or the to-be-evaluated management method according to the test whole-process state perception data, and automatically generates a test analysis report. According to different test types, the basis for test result analysis is obviously different, and the detailed judgment basis is each parameter determined in the "test data collection".

[0105] In this embodiment, through the Internet of Things platform, a large amount of data from intelligent perception terminals is collected. These data include voltage, current, frequency and other electric energy parameters, as well as the running state of the device and environmental conditions. Using big data analysis technology, the actual running scene can be parsed from these complex data, providing a basis for subsequent verification comparison. The parsed actual scene is compared with the pre-set verification scene. If they are consistent, it means that the collected data accurately reflects the actual power quality condition. On this basis, the abnormal stage data in the terminal perception data is further analyzed to determine the actual abnormal working condition and identify the device that occurs abnormality.

[0106] In this embodiment, once the actual abnormal condition is determined, it is necessary to determine whether the device that has experienced the abnormal condition is the device under test. If the actual sensing device corresponds to the device under test and its abnormal condition matches the pre-set abnormal operating condition of the device under test, it indicates that the device under test is experiencing the expected test condition. After confirming the abnormal condition, the analysis terminal sensing data in the governance phase, including the response and compensation measures of the device under test to the abnormal condition, and the effect of these measures. After the governance phase, continue to collect and analyze the post-governance data to evaluate the performance and effect of the device under test, including the recovery of power parameters and the stability of the device. According to the pre-set evaluation model, the Internet of Things platform can automatically analyze the governance phase data and post-governance data. The pre-set evaluation model may include the improvement degree of power quality indicators, the response time of the device and the compensation efficiency, etc. Through these analyses, the platform can automatically generate a test analysis report, which will include a detailed description of the abnormal condition, an evaluation of the effect of the governance measures and suggestions for subsequent improvements.

[0107] In this embodiment, the generated test analysis report will provide key insights that can help users and operators understand the performance of the device under test and guide them to make necessary adjustments. The report may include the following: detailed description of the actual abnormal condition and the time of occurrence, response time and compensation effect of the device under test, improvement of power quality after governance, comprehensive evaluation of device performance and optimization suggestions.

[0108] As a preferred embodiment of the present embodiment, the method for constructing the pre-set evaluation model comprises:

[0109] Obtain sample data corresponding to the governance phase data and post-governance data of the device under test during power governance, and labeled data corresponding to the sample data; construct an initial pre-set evaluation model, take the sample data and the labeled data as training data of the initial pre-set evaluation model respectively, train the initial pre-set evaluation model until the loss function of the initial pre-set evaluation model tends to fit, and obtain the final trained pre-set evaluation model.

[0110] In this embodiment, in order to build an evaluation model, first of all, the sample data of the to-be-tested treatment equipment in the electric energy treatment process needs to be obtained. These sample data include real-time electric energy parameters in the treatment stage (such as voltage, current, frequency, harmonic content, etc.), and data of the system recovery state after treatment. At the same time, the corresponding labeled data, that is, the data marked by experts or known results, are also needed to guide model learning. Before using the sample data for training, preprocessing is needed to improve data quality and make it suitable for model training. The preprocessing steps may include data cleaning (removing outliers and noise), normalization (making data on the same scale), feature engineering (extracting features that help model learning), etc. An initial preset evaluation model is built, which can evaluate the effect of electric energy treatment according to the data before and after treatment. This model may be based on machine learning algorithms such as random forest, support vector machine, neural network, etc., and the specific choice depends on the data characteristics and problem complexity. Then, the initial evaluation model is trained using the preprocessed sample data and labeled data. During the training process, the model learns the features of the sample data and the output of the labeled data, and gradually adjusts the internal parameters to reduce the prediction error. During the training process, the loss function of the model (such as mean square error, cross-entropy, etc.) is used to measure the difference between the predicted results and the actual labels. The goal of training is to minimize this loss function so that the model's predictions are as close to the actual results as possible. During the model training process, the performance of the model needs to be evaluated regularly to ensure that it does not overfit (i.e., performs well on training data but poorly on unseen test data) or underfit (i.e., the model is too simple and cannot capture the complex relationships in the data). Model performance can be optimized through cross-validation, adjustment of hyperparameters, etc. After multiple iterations of training and parameter adjustment, when the loss function tends to be stable and the model's performance on the validation set reaches a satisfactory level, the final trained preset evaluation model is obtained, which can accurately evaluate the effect of electric energy treatment and provide decision support for operators.

[0111] It can be understood that the preset evaluation model can accurately predict the effect of electric energy treatment and provide reliable data support for subsequent device optimization, while the preset evaluation model has good generalization ability and can work stably under different grid conditions and treatment scenarios. Through the evaluation of the automated preset evaluation model, manual intervention is reduced, evaluation efficiency and objectivity are improved, and the model can continuously learn and adapt with the addition of new data to cope with changes in power quality treatment grid conditions.

[0112] It can be understood that the embodiment constructs a transparent transformer area real platform, has a new type of intelligent power distribution system operation simulation capability, can support the development of intelligent transformer area power quality treatment application verification under the background of new type of power system, has comprehensive transformer area power quality abnormality simulation capability of transformer area voltage quality abnormality, three-phase imbalance, harmonic pollution, photovoltaic reverse delivery, etc., supports the development of various power quality treatment application function verification; at the same time, by constructing the real platform Internet of Things intelligent monitoring system, realizing platform state panoramic perception and test process transparent display, directly showing the test effect, adopting real simulation mode to develop power quality treatment function verification, providing a systematic real test environment, the test result has high reliability, and based on the platform management system, the scheme editing and parameter setting, process management and other functions can realize one-key generation of typical cases, improve the test efficiency and easy operation.

[0113] The above embodiment has the following effects:

[0114] The technical scheme of the application can accurately and reliably build a platform for simulation running by editing the test scheme and setting parameters of the transparent transformer area real platform and the verification scene, so as to have a new type of intelligent power distribution system operation simulation capability, support the development of various power quality treatment application function verification under the background of new type of power system, construct the Internet of Things to realize platform state panoramic perception and test process transparent display, directly show the test effect, accurately and reliably collect and acquire the simulated data, provide a systematic real test environment, the test result has high reliability, finally analyze the test result, improve the test efficiency and easy operation, at the same time, based on the terminal perception data collected by the Internet of Things platform, automatically perform hierarchical analysis, can improve the accuracy and efficiency of power quality analysis, improve the operation experience of users in power quality analysis and detection.

[0117] As a preferred scheme of the embodiment, the power quality treatment function verification scene includes: voltage quality treatment function verification scene, three-phase imbalance treatment function verification scene, harmonic treatment function verification scene and photovoltaic reverse delivery treatment function verification scene.

[0118] In the embodiment, based on the transparent transformer area real platform, the intelligent transformer area operation characteristics in the new type of power system can be completely simulated to provide a real transformer area test environment for developing transformer area power quality treatment application function verification.

[0119] As a preferred scheme of the embodiment, the parameter setting of the voltage quality treatment function verification scene specifically includes:

[0120] The transparent transformer and voltage regulator combination is used for overall transparent substation real platform power supply. The substation voltage is controlled by setting the voltage regulator parameters, thereby generating and providing substation voltage fluctuation and overvoltage operation scenarios. The line impedance parameters are adjusted by the line simulation device to simulate different feeder lengths, and the combination of different feeder lengths and different loads is performed in combination with the controllable simulation load in the platform, thereby reproducing the low voltage operation condition at the end of the substation. Based on the Internet of Things during low voltage power distribution, the substation voltage is obtained in real time as the initial voltage data of the substation voltage fluctuation test, and the change of the substation voltage during the test is continuously monitored as the test data under the voltage quality management function verification scenario, thereby completing the setting of the voltage quality management function verification scenario.

[0121] In this embodiment, the transparent transformer and voltage regulator combination is used for overall real platform power supply. The substation voltage is controlled by setting the voltage regulator parameters, thereby providing substation voltage fluctuation and overvoltage operation scenarios. The line impedance parameters are adjusted by the line simulation device to simulate different feeder lengths, and the combination of different feeder lengths and different loads is performed in combination with the controllable simulation load in the platform, thereby reproducing the low voltage operation condition at the end of the substation.

[0122] It should be noted that the substation voltage quality problem mainly focuses on voltage fluctuation, overvoltage and low voltage at the end. The transparent real experiment platform adopts the combination of the isolation transformer and the voltage regulator for overall real platform power supply. The rapid and accurate control of the substation voltage can be realized by setting the voltage regulator parameters, thereby providing the substation voltage fluctuation and overvoltage operation scenarios. The low voltage at the end of the substation is usually caused by unreasonable substation line length or feeder load configuration. In the real platform, the line impedance parameters can be flexibly adjusted by the line simulation device to simulate different feeder lengths, and the combination of different feeder lengths and different loads can be performed in combination with the controllable simulation load in the platform, thereby truly reproducing the low voltage operation condition at the end of the substation.

[0123] As a preferred scheme of this embodiment, the substation voltage is controlled by setting the voltage regulator parameters, specifically including:

[0124] The brush and coil contact position in the voltage regulator is adjusted to change the primary and secondary coil turn ratio, thereby adjusting the output voltage to control the substation voltage.

[0125] In the embodiment, the three-phase voltage regulator is a contact type autotransformer voltage regulator connected to the output end of the isolation transformer. After confirming the reliability of the connection, the output voltage is adjusted by adjusting the voltage regulator knob to change the contact position of the brush and the coil to change the turns ratio of the primary and secondary coils.

[0126] As a preferred scheme of the embodiment, the parameter setting of the three-phase imbalance treatment function verification scene specifically includes:

[0127] Based on the test scheme, the load imbalance degree of the transformer area is determined, and the controllable energy feedback load capable of imbalance operation is configured to set the three-phase power according to the load imbalance degree of the transformer area, so that the feeder of the transparent transformer area real platform runs in an imbalance state. The imbalance state running in the transparent transformer area real platform is treated by configuring an intelligent phase change switch, and a standardized interface is provided by the intelligent phase change switch, so that the three-phase imbalance treatment demonstration is carried out, and the to-be-tested equipment is connected and function tested, so that the setting of the three-phase imbalance treatment function verification scene is completed.

[0128] In the embodiment, the three-phase imbalance of the transformer area will increase the line loss of the line and the distribution transformer, reduce the operation efficiency of the power supply, and possibly endanger the safety of the distribution transformer and the user's electrical equipment. The controllable energy feedback load capable of imbalance operation is configured in the transparent transformer area real platform, which can set the real platform feeder to run stably within a certain imbalance degree range. The intelligent phase change switch is a commonly used device for treating the three-phase imbalance of the transformer area. The intelligent phase change switch is configured in the real platform and provides a standardized interface, which facilitates the connection and function test of the to-be-tested switch device while carrying out the three-phase imbalance treatment demonstration.

[0129] In the embodiment, the controllable energy feedback load capable of imbalance operation is configured in the transparent transformer area real platform. The controllable energy feedback load can independently set the ABC three-phase power. According to the specific needs of the three-phase imbalance treatment function test, various load imbalance degrees of the transformer area can be flexibly set to provide different power and different imbalance degrees for the test scene of the intelligent phase change switch. The intelligent phase change switch is configured in the real distribution transformer area, and the intelligent phase change switch is a commonly used device for treating the three-phase imbalance of the transformer area. After the real platform realizes the setting of the imbalance operation state of the transformer area based on the controllable energy feedback load, the intelligent phase change switch is communicated, and the load phase change of the transformer area is controlled through the intelligent phase change switch control panel to ensure the overall three-phase balanced operation of the distribution transformer area, and the three-phase imbalance treatment function demonstration is completed.

[0130] As a preferred scheme of the embodiment, the harmonic management function verification scene parameter setting specifically includes:

[0131] Based on the positive direction harmonic output of the energy feedback type controllable simulation load, the harmonic is injected into the power grid in the transparent transformer station real model platform through the energy feedback mode, so that the transparent transformer station real model platform simulates the harmonic pollution scene; the interface of the transformer station reserved harmonic management device accesses the to-be-tested equipment, and the Internet of Things of the transformer station power distribution is used to monitor the change of the transformer station harmonic in real time, so that the setting of the harmonic management function verification scene is completed.

[0132] In the embodiment, based on the harmonic output capability of the energy feedback type controllable simulation load, the harmonic is injected into the power grid through the energy feedback mode, so that the harmonic pollution typical scene simulation of the transparent transformer station real model platform is realized.

[0133] It should be noted that the energy feedback type controllable simulation load in the transparent transformer station real model platform has a harmonic output capability, and specific harmonics are injected into the power grid through the energy feedback mode, so that the harmonic pollution typical scene simulation of the real model platform is realized.

[0134] In the embodiment, the energy feedback type controllable simulation load has a bidirectional energy flow function, can realize automatic seamless switching in the forward and reverse directions, and supports customized generation of different frequency harmonics injected into the real model platform, so as to realize the construction of transformer station harmonic pollution operation scenes with different frequencies and different contents. After the harmonic pollution scene construction is completed, the interface of the transformer station reserved harmonic management device accesses the to-be-tested equipment, and the Internet of Things of the transformer station power distribution is used to monitor the change of the transformer station harmonic in real time, so as to complete the harmonic management function verification of the to-be-tested equipment.

[0137] In the embodiment, by configuring a programmable analog photovoltaic cell, the characteristics of photovoltaic modules under different light intensities, different temperatures, and different shadow conditions are simulated, and a photovoltaic curve editing function is set. The transition of the photovoltaic system from a normal operating state to a photovoltaic reverse feeding state is set through a preset photovoltaic characteristic curve, thereby providing a test field for photovoltaic reverse feeding management function verification.

[0138] It should be noted that the rapid development of new energy technology has led to a large number of distributed photovoltaic access in low-voltage distribution areas, which brings convenience to users while posing a risk of photovoltaic reverse feeding. Photovoltaic reverse feeding is caused by factors such as shadow, uneven local illumination, or temperature gradient of the photovoltaic power generation system, resulting in the output voltage of the photovoltaic module being lower than the voltage at the load end, causing current to flow from the load end to the photovoltaic module. Photovoltaic reverse feeding can cause the voltage at the load end of the distribution area to be too high and the bus voltage to rise, seriously affecting the power quality of the distribution area.

[0139] The programmable analog photovoltaic cell configured in the real-type distribution area can simulate the characteristics of photovoltaic modules under different light intensities, different temperatures, and different shadow conditions, and support the photovoltaic curve editing function. The transition of the photovoltaic system from a normal operating state to a photovoltaic reverse feeding state can be set through a preset photovoltaic characteristic curve, thereby providing a test field for photovoltaic reverse feeding management function verification.

[0140] In the embodiment, a high-power programmable photovoltaic simulation system is configured in a real-type distribution area, including a programmable analog photovoltaic cell and a photovoltaic inverter. The photovoltaic simulation cell can simulate the characteristics of photovoltaic modules under different light intensities, different temperatures, and different shadow conditions. The photovoltaic inverter can set different active and reactive power outputs and support power curve setting. Combined with the photovoltaic simulation cell, a variety of photovoltaic power generation system operating characteristics can be simulated in the real-type platform in the distribution area. Based on the photovoltaic simulation system, the photovoltaic output curve in the real-type platform is set, and the programmable simulation load power curve in the distribution area is set. The photovoltaic power generation capacity in the distribution area and the load power in the distribution area can be flexibly matched, the real operation simulation of the photovoltaic normal operation to photovoltaic reverse feeding scenario in the distribution area is completed, and the photovoltaic reverse feeding management function verification scene simulation is provided. During the function verification process, the smart meters and smart sensors in the distribution area acquire the distribution area voltage, current, and power generation data in real time, providing data support for evaluating the management effect.

[0141] The above embodiments have the following effects:

[0142] The technical scheme of the present application can accurately and reliably build a platform for simulation running by editing the test scheme and setting parameters of the transparent transformer area real platform and verifying the parameter setting of the scene, so that it has the running simulation capability of the new intelligent power distribution system, can support the verification of various power quality treatment application functions under the background of the new power system, and can realize panoramic perception of platform state and transparent display of test process through the construction of Internet of Things, directly display the test effect, accurately and reliably collect and acquire the simulated data, provide a systematic real test environment, the test result has high reliability, finally analyze the test result, improve the test efficiency and easy operation, and based on the terminal perception data collected by the Internet of Things platform, automatically perform hierarchical analysis, which can improve the accuracy and efficiency of power quality analysis, and improve the operation experience of users in power quality analysis and detection.

[0151] ​​(3) Test data monitoring

[0152] During the test, the power quality monitoring device obtains real-time three-phase current data at the outlet T1 of the distribution transformer (including the voltage regulator), and transmits the data to the Internet of Things management platform based on the Internet of Things for data display and analysis through the intelligent gateway. Similarly, the measured switch SB' uploads its own switch state to the Internet of Things platform in real time through the intelligent gateway.

[0153] (4) Test result analysis

[0154] Based on the three-phase current data at T1 and the state data of the measured commutating switch SB', the three-phase imbalance treatment function of the commutating switch can be analyzed. In this embodiment, it is mainly reflected that after the three-phase simulation load enters an unbalanced operating state at 1 min, the three-phase unbalanced current data at T1 will be detected, and at the same time, the commutating switch SB' controller also obtains the three-phase unbalanced current of the feeder. After that, the commutating action will be triggered without power interruption, and the single-phase simulation load Load3 will be switched from B phase to A phase for operation, so that the detected three-phase current data at the outlet T1 of the transformer returns to a balanced state. By observing whether the commutating switch acts and the action delay during the test, the three-phase imbalance treatment application function can be evaluated.
