Description

Technical Field

[0001] This invention relates to the field of power distribution business application testing technology, and specifically to a smart converged terminal power distribution business application testing system and method. Background Technology

[0002] The intelligent converged terminal is the core edge computing node of the distribution transformer area. By deploying relevant power distribution business applications on the terminal, it can realize data collection, aggregation, remote control and other functions of intelligent power distribution equipment in the transformer area (such as low-voltage intelligent circuit breakers, intelligent reactive power compensation capacitors, etc.). Through edge computing and coordinated control, it can achieve transformer area autonomy and meet the needs of power distribution related businesses. For example, it can analyze power outage and restoration information on-site to improve fault handling efficiency and enhance power supply reliability. Or, based on the operating status of the transformer area, it can coordinate and control reactive power compensation devices, on-load tap changer tap positions, phase switching switches, line voltage regulators, distributed photovoltaic inverters, charging piles, transformer area energy storage, etc. on-site to carry out online power quality adjustment, transformer overload management, etc. Or, by monitoring the operating status of transformers and other equipment in real time, it can calculate and evaluate the health status of transformers in real time, handle abnormal transformer conditions in advance, and ensure the safe operation of equipment.

[0003] Conducting complete and accurate testing on the power distribution business applications of intelligent converged terminals is a necessary step and basic requirement to verify whether they meet the relevant technical requirements and functional design. It is related to whether they can operate reliably and stably in the field and whether they can meet business needs.

[0004] However, there is currently no unified standard for testing intelligent converged terminal power distribution business applications, and existing testing methods mainly have the following problems: First, the testing scenarios are not fully covered. Traditional testing methods often use real equipment for testing, but due to limitations such as space and cost, it is difficult to configure a full range of intelligent power distribution equipment, resulting in some business application scenarios not being covered.

[0005] Second, the stability of test data is insufficient. In actual operation, real equipment is affected by factors such as environment and load, resulting in fluctuations in output data, making it difficult to guarantee the consistency and repeatability of test results.

[0006] Third, the testing efficiency is low. Building a real testing platform requires a lot of time and cost, and the equipment debugging and troubleshooting processes are time-consuming.

[0007] Fourth, the test results are inaccurate. If pure digital simulation testing is used, the test data will be inaccurate and the deviation will be large.

[0008] Fifth, there is a lack of collaborative testing capabilities. Existing testing methods struggle to effectively combine real equipment operating data with simulated equipment data, failing to create a complete operational data scenario. Summary of the Invention

When the real equipment data is incomplete or inaccurate, the simulator is started to generate stable simulated data, ensuring the consistency and repeatability of the test results. (3) This embodiment adopts a modular design, with no upper limit on the number of transformer substation power distribution function cabinets.

The platform coordination control and test analysis subsystem can automatically generate test scenarios and automatically analyze test data, improving test efficiency.

This embodiment can realize the automation of communication protocol consistency testing and power distribution business application testing through the multi-module collaboration of the platform coordination control and test analysis subsystem, reducing manual intervention and improving the objectivity of testing.

[0048] Example 2 This embodiment uses a low-voltage reactive power compensation application test as an example to explain in detail the working principle of the present invention.

[0049] The testing procedure for low-voltage reactive power compensation applications is as follows: Q1: The platform coordination control and test analysis subsystem starts the real-world platform and sets up the business operation data for the low-voltage reactive power compensation operation scenario. The platform coordination control and test analysis subsystem sets up the reactive power compensation scenario through the power distribution business scenario generation module of the test platform, including adjusting the load parameters of the adjustable load function cabinet in the transformer area, setting the compensation capacity of the reactive power compensation cabinet, etc., to simulate the operating condition of insufficient reactive power in the transformer area.

[0050] Q2: The low-voltage reactive power compensation application within the intelligent converged terminal acquires operational data, processes it, and uploads it to the business main station's test subsystem and platform coordination control and test analysis subsystem. The low-voltage reactive power compensation application collects parameters such as transformer area voltage, current, active power, and reactive power, calculates the power factor, determines whether reactive power compensation devices need to be activated, and uploads the collected and processed data.

[0051] Q3: The platform coordination control and test analysis subsystem conducts data comparison and analysis by acquiring low-voltage reactive power compensation application data from intelligent converged terminals and data from the business main station test subsystem.

[0052] Q3.1: The test content includes: (1) 645 protocol and Modbus communication protocol conformance test: The intelligent power distribution equipment communication protocol conformance test module tests whether the communication protocol between the intelligent fusion terminal and the reactive power compensation equipment conforms to the standard, and verifies whether the communication frame format, data definition, transmission mechanism, etc. are standardized.

[0053] (2) Low-voltage reactive power compensation performance application test: The active power measurement error of the test voltage and current shall not exceed ±0.5%, and the reactive power measurement error shall not exceed ±2%. The test data analysis and display module compares the voltage, current, active power, and reactive power data uploaded by the intelligent fusion terminal with the standard measurement values ​​and calculates the measurement error.

[0054] (3) Low-voltage reactive power compensation function application test: The remote signaling uptime is tested to be within 1 second and the remote control response time is tested to be within 5 seconds. The remote signaling uptime refers to the time from the change of the state of the intelligent device to the intelligent fusion terminal receiving the state change information; the remote control response time refers to the time from the intelligent fusion terminal issuing the control command to the intelligent device executing the command.

[0055] Q3.2: If the test results do not meet the above requirements, possible reasons include real equipment failure, communication anomalies, and data fluctuations. In this case, the platform's coordination, control, and test analysis subsystem will run the low-voltage reactive power compensation communication data interaction simulator in the control area, generating simulated low-voltage reactive power compensation service interaction data and interacting with the corresponding low-voltage reactive power compensation application in the intelligent converged terminal. The data generated by the simulator is stable and controllable, eliminating the influence of factors such as real equipment failure and communication anomalies, and accurately testing the performance and functionality of the low-voltage reactive power compensation application. Return to Q2 and repeat data collection and analysis until the test results meet the requirements.

[0056] Example 3 This embodiment uses a phase-switching switch application test as an example to illustrate the application of the present invention in other business scenarios.

[0057] The platform's coordination, control, and testing analysis subsystem sets up operating scenarios for the commutator switches, including setting three-phase load imbalance and triggering commutation conditions. The commutator switch application within the intelligent fusion terminal monitors the three-phase load imbalance in real time. When the imbalance exceeds a threshold, it issues a commutation command to control the commutator switch's operation. The platform's coordination, control, and testing analysis subsystem collects three-phase current data before and after the commutator switch operation, analyzes the commutation effect, and simultaneously tests the consistency of the communication protocol and the application's performance and functionality.

[0058] If the actual commutation switch equipment malfunctions or communication is abnormal, the platform's coordination control and test analysis subsystem will start the commutation switch communication data interaction simulator to generate stable simulated commutation data, which will then interact with the intelligent fusion terminal commutation switch application to complete the test.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention.
