The role of supercapacitors is becoming increasingly prominent. However, in order to give full play to the performance advantages of supercapacitors and ensure their reliability and stability in practical applications, it is particularly important to conduct comprehensive performance tests on supercapacitors. Traditional testing methods often focus on a single performance indicator, such as capacity, internal resistance or charge and discharge efficiency, which is difficult to fully reflect the comprehensive performance of supercapacitors under complex working conditions.

[0029] In order to solve the above technical defects, the inventor provides a supercapacitor testing method, system and computer equipment.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: In a first aspect, an embodiment of the present invention provides a supercapacitor testing method, such as Figure 1 As shown, including: S101. Configure test equipment and build a test environment. For example, first prepare supercapacitor cells or modules, bidirectional power conversion devices, energy management devices, high-precision current and voltage testers, oscilloscopes, and temperature sensors. Then build a test environment that simulates the frequency modulation of a thermal power unit, and set up an AC power supply, a signal generator that simulates grid frequency fluctuations, and a data acquisition device. Specifically, during the preparation process, a 2.7V supercapacitor monomer or a 300V supercapacitor module can be selected. The capacity unit of the 2.7V supercapacitor monomer is 100F~3000F, and the capacity range of the 300V supercapacitor module is 10KF~100KF, and the temperature tolerance range is -40℃ to +65℃; the power level of the bidirectional power conversion device is 50KW~1MW, and its control interface supports CAN / Modbus communication protocol; the energy management device must support charging and discharging strategy configuration, and the communication protocol is compatible with IEC61850 or DNP3.0; the accuracy of the high-precision current / voltage tester is ±0.1%, and the bandwidth is ≥100kHz; the sampling rate of the oscilloscope is ≥1GS / s, and the bandwidth is ≥200MHz; the accuracy of the temperature sensor is ±0.5℃, and the response time is <1s. During the test environment construction process, the positive and negative poles of the supercapacitor module are connected to the DC side of the bidirectional power conversion device (PCS) through copper bars, and the AC side of the PCS is connected to the power grid simulator or the real power grid (an isolation transformer is required). A high-precision shunt (for current measurement) is connected in parallel to the DC bus, and the voltage test point is directly connected to the supercapacitor terminal. The signal output end of the current / voltage tester is connected to the oscilloscope and data acquisition card, and the temperature sensor is attached to the surface of the supercapacitor monomer and evenly distributed at least 3 measurement points; the signal line is connected to the data acquisition system, and the EMS communicates with the PCS and the test instrument through the CAN bus to receive real-time data and issue control instructions. Install circuit breakers and fuses, with a rated current of 1.5 times the maximum test value, and all equipment shells are connected to independent grounding piles, with a grounding resistance of ≤4Ω. Use a megohmmeter (500V gear) to detect the insulation resistance of the DC bus to the ground (required to be ≥10MΩ). Furthermore, the configuration parameters are set, the working mode of the bidirectional power conversion device is set to constant current charging and discharging and constant voltage charging, and the protection thresholds are overvoltage (1.2 times the rated voltage), overcurrent (1.5 times the rated current), and overtemperature (≥65°C). During the whole process, the supercapacitor monomer or module is used as the test object to directly evaluate its performance; the bidirectional power conversion device simulates the charging and discharging process of the supercapacitor in the frequency modulation application; the energy management device controls and manages the energy flow of the supercapacitor; the high-precision current and voltage tester accurately measures the current and voltage changes of the supercapacitor; the oscilloscope is used to capture and analyze fast transient events in the circuit. The temperature sensor monitors the temperature changes of the supercapacitor during operation.The test environment simulating the frequency modulation of thermal power units provides a test scenario close to actual application; the AC power supply is set to provide a stable power supply for the test system; the signal generator simulating the frequency fluctuation of the power grid can simulate the frequency fluctuation in the actual power grid to test the response ability of the supercapacitor; the data acquisition device automatically collects and records all data during the test. By building a test environment simulating the frequency modulation of thermal power units, the working conditions of supercapacitors in actual applications can be simulated more realistically, thereby improving the accuracy and reliability of the test; secondly, the prepared test equipment can comprehensively evaluate the performance of supercapacitors, including charging and discharging characteristics, response speed, temperature stability, etc., to ensure that there are no omissions in performance, and the use of high-precision current and voltage testers and temperature sensors can accurately measure and record various parameters of supercapacitors during operation, providing an accurate basis for subsequent data analysis; through the data acquisition device, all data during the test can be automatically collected and recorded, reducing human errors and improving test efficiency; finally, the oscilloscope can capture fast transient events in the circuit, which helps to diagnose potential performance problems or faults.

[0031] S102. Using the test environment, perform a composite test on the equipment to be tested to obtain test data; illustratively, using the test environment, perform a charge and discharge characteristic test, a response speed test, a stability test, and a compatibility test on the test equipment; wherein the stability test includes a long-term charge and discharge test and a temperature stability test, and the compatibility test includes a compatibility test with a thermal power component control system and a compatibility test with other energy storage devices. In the charge and discharge characteristic test, the supercapacitor is charged and discharged by the test equipment, and its voltage and current changes are recorded to evaluate its charge and discharge efficiency and energy storage capacity; the response speed test tests the response speed of the supercapacitor to the frequency fluctuation of the power grid, that is, the time required for it to switch from a charging state to a discharging state or from a discharging state to a charging state; the stability test tests the performance stability of the supercapacitor under long-term operation and at different ambient temperatures to evaluate its reliability in practical applications; the compatibility test tests the compatibility of the supercapacitor with the thermal power component control system and other energy storage devices to ensure that it can be seamlessly integrated with other systems in practical applications. Through composite testing, we can comprehensively and systematically understand the performance of supercapacitors in various aspects such as charging and discharging, response speed, stability and compatibility, and provide data support for further optimization of products; at the same time, the test data can verify whether the supercapacitor meets the design requirements and reveal its potential performance bottlenecks. Secondly, through stability testing and compatibility testing, we can ensure the reliability and compatibility of supercapacitors in actual applications and reduce the risk of system failure.

[0032] Furthermore, during the long-term charge and discharge test, the durability of the supercapacitor can be effectively evaluated through long-term charge and discharge cycles, simulating the long-term charge and discharge conditions that the supercapacitor may encounter in actual use, thereby predicting its service life; and the long-term charge and discharge test can monitor the performance degradation of the supercapacitor during continuous use. By observing the trend of performance degradation, potential problems can be discovered in time, providing a basis for product maintenance and replacement. During the temperature stability test, the temperature stability test can verify the working stability and performance of the supercapacitor under different temperature environments, ensuring that the supercapacitor can maintain reliable performance under various climates and working conditions; in addition, under extreme conditions of high or low temperatures, the supercapacitor may face performance degradation, damage or even safety risks. Through the temperature stability test, these potential problems can be discovered and solved in time to ensure the safety of the supercapacitor under various temperature conditions.

[0033] During the compatibility test of the thermal power component control system, the compatibility test with the thermal power component control system can ensure that the supercapacitor can be seamlessly connected to the existing thermal power system, realizing the mixed use of the energy system, which not only improves the flexibility and efficiency of energy use, but also reduces the cost of system transformation and upgrade; the compatibility test can discover and solve the possible conflicts or mismatches between the supercapacitor and the thermal power component control system, reduce the possible failures or interruptions in actual operation, and thus enhance the stability of the entire energy system. Through compatibility testing, potential problems can be identified and solved in advance, reducing the frequency of later maintenance and repairs, thereby reducing maintenance costs.

[0034] The compatibility test with other energy storage devices helps to achieve complementary advantages among various energy storage devices and improve energy efficiency and reliability. For example, during peak power demand periods, different types of energy storage devices can work together to ensure stable power supply.

Through systematic data collection and processing and analysis, the actual performance of supercapacitors in frequency modulation applications can be more accurately evaluated to avoid subjective assumptions and misjudgments; at the same time, data analysis helps to promptly discover the shortcomings and problems in the performance of supercapacitors and provide targeted improvement directions.
