Technical Field
[0001] This invention belongs to the field of energy storage power station testing technology, and particularly relates to an integrated testing device and method for energy storage power stations. Background Technology
[0002] Electrochemical energy storage power stations are costly to build, exhibit significant electrochemical characteristics, and possess abundant monitoring points, generating large volumes of data with extremely high analytical value. Currently, data acquisition in energy storage power stations primarily relies on traditional computer servers for data collection and analysis, lacking dedicated acquisition terminals and lightweight analysis tools. Traditional computer servers have stringent requirements regarding usage scenarios, spatial environments, and network conditions, and are often fixed in place, resulting in large size and weight, making them unsuitable for mobile environments. While server-based acquisition devices are suitable for long-term, uninterrupted daily early warning analysis of power stations, different power stations have varying early warning cycle requirements. Therefore, more flexible terminal devices are needed to meet the power station's need for continuous equipment monitoring and early warning analysis in its daily operating environment.
[0003] However, existing testing equipment for energy storage power stations has the following problems: Distributed architecture: Traditional detection relies on multiple independent devices (sensors, data loggers, servers), which are complex to deploy and have poor coordination.
[0004] Insufficient mobility: Fixed servers are difficult to adapt to the flexible testing needs of distributed power stations, and manual handling costs are high.
[0005] Poor hardware compatibility: Different power plants have different interface protocols and communication standards, making it difficult for existing equipment to adapt to multiple scenarios.
[0006] Data processing delay: Data needs to be transmitted back to the cloud for analysis, resulting in low real-time performance and dependence on network stability.
[0007] Insufficient algorithm-hardware coordination: Existing equipment lacks dedicated analysis algorithms tailored to the characteristics of energy storage power stations, and the algorithm execution is disconnected from the hardware data acquisition process, making real-time early warning impossible.

[0033] like Figure 2 As shown, this invention proposes an integrated testing method for energy storage power stations. It achieves adaptive connection with different power station equipment through the multi-protocol interface array of a portable device and the protocol recognition capability of an FPGA chip; utilizes the device's signal conditioning unit and sensor expansion slots to complete the acquisition and preprocessing of multi-dimensional raw signals; achieves real-time edge computing by executing dedicated analysis algorithms for key equipment in the energy storage power station in parallel through a CPU+GPU heterogeneous computing unit; finally, it generates a detailed testing report and ensures the integrity of data transmission and storage through a multi-mode communication module and a breakpoint resume mechanism. The steps include... S1. Transport the portable testing equipment to the target power station. After connecting the communication interface, the equipment automatically identifies the protocol and establishes a communication connection through the FPGA chip.
[0034] S1.1 Transport the portable testing equipment to the target energy storage power station site by a single person; and select a dedicated cable according to the interface type of the power station equipment to connect the communication interface of the power station EMS (Energy Management System) to the multi-protocol interface array of the equipment.

Match the key features of the extracted handshake signal one by one with the internally stored protocol feature library (which includes feature parameters of commonly used power plant protocols such as RS-485 / 232, CAN, and Modbus-TCP) and load the corresponding driver configuration file.
[0040] In this embodiment, if the match is successful, the FPGA chip automatically identifies the corresponding protocol type, calls and loads the driver configuration file corresponding to the protocol from the device storage module, and completes the protocol parsing and communication parameter configuration. If a match fails, the FPGA chip initiates a machine learning classification model (based on the random forest algorithm), inputting the collected unknown protocol features into the model for classification and identification. The model's training set contains features of various power plant protocols, giving it a strong ability to identify unknown protocols. Through multi-dimensional analysis of the features, a temporary driver configuration file is generated and loaded to achieve communication adaptation with devices using unknown protocols.
[0041] S1.5 After the driver configuration file is loaded, a data acquisition request command is sent to the power station EMS, and the response signal from the power station EMS is received to verify the stability and effectiveness of the communication connection.
[0042] In this embodiment, if a normal response signal is received, it indicates that the communication connection is successful and the device enters the data acquisition preparation state; if no response signal is received or the response signal is abnormal, the device will re-execute the protocol identification process, repeating it up to 3 times. If effective communication still cannot be established, an alarm message will be sent.
[0043] S2. Collect multi-dimensional power plant equipment operation data and use edge computing algorithms to analyze equipment status in real time and provide real-time early warning.

At the same time, the weak signal is amplified to a suitable acquisition range. The amplification gain can be automatically adjusted according to the signal strength, up to 100 times.
[0048] 2. Filtering Process: An 8th-order Butterworth low-pass filter is used for anti-aliasing filtering of the signal. The cutoff frequency can be adjusted via FPGA programming (adjustment range: 10Hz~100kHz), effectively filtering out high-frequency noise and interference signals in the signal. The filter circuit consists of an OPA227 operational amplifier and precision resistors and capacitors to ensure the stability and reliability of the filtering effect.
[0049] 3. AD Conversion: The conditioned analog signal is converted into a digital signal using a 24-bit high-precision ADC. Differential sampling is employed during the conversion process to improve anti-interference capability and conversion accuracy. The digital signal is connected to the FPGA chip via the SPI bus, and then transmitted from the FPGA chip to the main control module.
[0050] S2.4. Using edge computing algorithms, the mathematical signals of the energy storage power station are analyzed and processed in real time to obtain the analysis results.
[0051] In this embodiment, the edge computing algorithm used in this invention mainly includes: 1.

The steps include: a. Data input: Extract daily, monthly, and yearly temperature data sequences of transformers and converters from the storage module to form temperature trend curves.
[0052] b. Calculation of characteristic parameters: Based on the temperature trend curve, calculate the temperature change rate k (unit: ℃ / day or ℃ / month) and the heat dissipation coefficient λ (unit: W / ℃); where the temperature change rate k reflects the rate of change of equipment temperature over time and is calculated by a linear fitting algorithm; the heat dissipation coefficient λ reflects the heat dissipation capacity of the equipment and is calculated based on the heat conduction equation and equipment structural parameters, i.e., λ=Q / ΔT, where Q is the heat dissipation power of the equipment and ΔT is the temperature difference between the equipment and the environment.
[0053] c. Aging coefficient calculation: Based on the calculated temperature change rate and heat dissipation coefficient, the equipment aging coefficient S is calculated, and its formula is expressed as follows: S = k × (1 / λ) Among them, the aging coefficient S comprehensively reflects the impact of the equipment temperature change rate and heat dissipation capacity on equipment aging. The larger the S value, the more serious the degree of equipment aging.
[0054] d. Early warning judgment: Compare the calculated aging coefficient S with the preset threshold. Compare. Threshold Custom settings can be configured based on equipment type, service life, and power plant operation and maintenance requirements. Default values are available. =1.
[0055] Optionally, when When this occurs, an aging warning is triggered, generating the warning message "The transformer / converter is at a high level of aging; it is recommended to shorten the inspection cycle and perform targeted maintenance." When this time is reached, it indicates that the equipment is in normal aging condition and no warning information is generated.
[0056] 2. Cell Thermal Runaway Prediction Algorithm: An LSTM-based time-series prediction model is used to predict the probability of thermal runaway risk by analyzing historical operating data of the battery cell. The steps include: a. Data Input: Extract the cell voltage difference ΔV (unit: mV), internal resistance change rate ΔR (unit: % / day), and temperature gradient from the storage module over a certain period (e.g., 30 days). Key parameter data such as T (unit: ℃ / cm) are used to form a time series data sequence.
[0057] b. Model Construction and Optimization: An LSTM time series prediction model is constructed, which includes an input layer, three hidden layers (128 neurons per layer) and one output layer. During training, the adaptive moment estimation (Adam) optimization algorithm is used to minimize the prediction error (cross-entropy loss function).
[0058] c. Calculation of thermal runaway risk probability: Calculate the thermal runaway risk probability using the trained LSTM time series prediction model.
[0059] In this embodiment, the present invention converts time-series data sequences into feature vectors that the model can process; and uses the ReLU activation function to enhance the nonlinear fitting ability of the model, and effectively captures long-term dependencies in time-series data through gating mechanisms (input gate, forget gate, output gate); and uses the Sigmoid activation function to map the prediction results to the [0,1] interval and output the probability P of thermal runaway risk.
[0060] Optionally, during device operation, the model parameters can be updated via a cloud platform to continuously optimize prediction accuracy.
[0061] d. Early warning judgment: Based on the calculated probability P of thermal runaway risk, an early warning judgment is made. Optionally, when the probability of thermal runaway risk P>0.7, a thermal runaway warning is triggered, and a warning message "The risk of thermal runaway of the battery cell is high, please stop the machine immediately for inspection" is generated; when P≤0.7, it indicates that the battery cell is operating normally and no warning message is generated.
[0062] 3. Battery Cluster Consistency Assessment Algorithm: By analyzing the voltage and SOC data of each cell within the battery cluster, the consistency status of the battery cluster is assessed. The steps include: a. Data input: Extract daily and monthly voltage trend data and SOC data of battery clusters from the storage module to form voltage sequence and SOC sequence of each cell.
[0063] b. Characteristic parameter calculation: Calculate the voltage standard deviation σ and SOC deviation ΔSOC of the cells within the battery cluster; where the voltage standard deviation σ is calculated using the overall standard deviation formula, which is expressed as follows:
[0064] Where n is the number of cells in the battery cluster that are included in the calculation; Let be the measured voltage value of the i-th cell; The average voltage value of the cells involved in the calculation within the battery cluster.
[0065] Optionally, the voltage standard deviation σ reflects the dispersion of the voltage of each cell. The larger the value of σ, the worse the voltage consistency. The SOC deviation value ΔSOC is the difference between the maximum and minimum SOC values of each cell in the battery cluster. The larger the value of ΔSOC, the worse the SOC consistency.
[0066] c. Consistency Coefficient Calculation: The consistency coefficient C of the battery cluster is calculated using the consistency coefficient formula, where the consistency coefficient formula is expressed as: C = 1 / (σ×ΔSOC) Among them, the consistency coefficient C is positively correlated with the consistency of the battery cluster. The larger the C value, the better the consistency of the battery cluster; the smaller the C value, the worse the consistency of the battery cluster.
[0067] d. Early warning judgment: Compare the calculated consistency coefficient C with the preset threshold. Comparison; where the threshold Custom settings can be configured based on battery cluster type, service life, and power plant operation and maintenance requirements. Default values are available. =0.5. When When this occurs, a consistency warning is triggered, generating the warning message "Battery cluster consistency is poor; it is recommended to perform cell balancing or replace abnormal cells." When this occurs, it indicates that the battery cluster consistency is normal and no warning information is generated.
