Description

Technical Field

[0001] This application relates to the field of power grid control technology, and in particular to a real-time electromagnetic transient simulation device. Background Technology

[0002] Photovoltaic, wind power and other new energy power generation systems have become the main source of incremental power grid growth. With the high proportion of new energy connected to the grid, the transient processes of the power grid are becoming more complex and the sudden changes in faults are becoming faster. Traditional electromechanical transient simulation can only describe slow dynamic processes such as generator speed and grid frequency, and it is difficult to capture the microsecond-level electromagnetic transient phenomena caused by high-frequency switching of converters. Electromagnetic transient simulation has become an important tool for the analysis of new energy grid connection. It can analyze the switching characteristics of power electronic devices and the instantaneous changes of transient current / voltage in microsecond-level steps, accurately restore the interaction dynamics between new energy systems and the power grid, and provide data support for the optimization of grid connection performance.

[0003] However, the actual switching changes in power grid systems are instantaneous, occurring on the order of microseconds or even sub-microseconds. This makes it difficult to integrate electromagnetic transient simulations into hardware-in-the-loop testing. Therefore, real-time electromagnetic transient simulations are gradually replacing conventional offline electromagnetic transient simulations. Current technologies typically implement real-time simulation calculations using a "task distribution - FPGA calculation - CPU parsing" model. However, the CPU's processing speed is difficult to match the FPGA's calculation speed, resulting in a time difference in data interaction between the two. Typically, the FPGA calculation step size is on the order of microseconds, while the interaction step size is on the order of tens of microseconds. This leads to a large number of FPGA calculated values ​​remaining unobtained and unobservable, hindering transient analysis of the power grid.

[0004] Currently, no effective solution has been proposed for improving the reliability of electromagnetic transient simulation of power grids in related technologies. Summary of the Invention

[0022] This application provides an electromagnetic transient real-time simulation device. Figure 1 This is a structural block diagram of an electromagnetic transient real-time simulation device according to an embodiment of this application, such as... Figure 1 As shown, the device includes a small-step simulation calculation device, a global data acquisition device, and a data processing device; The small-step simulation computing device is equipped with an FPGA processing unit, which is used to perform micrometer-level or sub-microsecond-level step-level calculations on the data acquired from the external physical controller to obtain electromagnetic transient simulation results. The full-domain data acquisition device is equipped with an FPGA processing unit, which is used to acquire the electromagnetic transient simulation results of each step obtained by the small-step simulation calculation device in real time and transmit them to the data processing device. The data processing device is equipped with a CPU processing unit, which is used to perform simulation analysis on the electromagnetic transient simulation results and display the simulation analysis results to the host computer or user terminal.

[0023] It should be noted that in existing technologies, to achieve real-time electromagnetic transient simulation, a "simulation task issuance - FPGA calculation mode - CPU parsing" model is typically adopted. However, the processing speed of the CPU is slower than that of the FPGA, especially for small-step calculations at the microsecond or even nanosecond level. The CPU struggles to acquire data for each small step, and typically uses interval data acquisition, for example, the CPU acquires data every 50µs. This model cannot perform data analysis and judgment for each step calculation value in actual data acquisition and observation, resulting in the loss of high-frequency transient data and insufficient hardware-in-the-loop simulation accuracy. For example, the response of the physical controller (such as protection command triggering) depends on real-time simulation data. The loss of high-frequency data will cause a "time lag" in the interaction between the controller and the simulation system, and the simulation results cannot reflect the true transient characteristics of the converter, affecting the accuracy of grid-connected performance testing of new energy power generation systems.

[0024] Therefore, this application proposes an electromagnetic transient real-time simulation device with a full-domain data acquisition function. The full-domain data acquisition function is used to acquire and cache the data of all step-size calculations of the FPGA, and the data is uploaded to the CPU to form a file and cached. This enables the acquisition of data for each step-size and the observation of the waveform.

[0025] In some embodiments, the small-step simulation computing device supports microsecond-level data interaction communication, cooperating with the real-time output of the full-domain data acquisition device to achieve microsecond-level data interaction communication between the small-step simulation computing device and the data processing device. The external physical controllers supported by the small-step simulation computing device for simulation calculations include power controllers, switch controllers, resistor controllers, capacitor controllers, and inductor controllers.

[0026] It should be noted that the small-step simulation computing device is equipped with a high-performance FPGA processing unit (with a built-in electromagnetic transient simulation kernel), supporting simulation calculations with sub-microsecond step sizes; it works in conjunction with a global data acquisition device to support microsecond-level data interaction and communication with the data processing device (CPU); and it supports simulation calculations for various components such as power supplies, switches, resistors, capacitors, and inductors. Furthermore, it also supports functions such as built-in PWM switch control and external physical controller switching control.

[0027] In some embodiments, based on the global data acquisition device, the waveform sampling frequency of the data acquired by the small-step simulation computing device is not controlled by the data interaction step size between the small-step simulation computing device and the data processing device; the waveform sampling frequency is only controlled by the calculation step size of the small-step simulation computing device, that is, if the calculation step size of the small-step simulation computing device is 1µs, then the waveform sampling frequency is 1000kHz.

[0028] It should be noted that the output of the small-step simulation computing device is real-time. After being parsed by the data processing device, the waveform is displayed to the host computer / user terminal in real time. In the prior art, the waveform sampling frequency of the data acquired by the small-step simulation computing device is controlled by the data interaction step size between the FPGA and the CPU. If the interaction step size between the data processing device (CPU) and the small-step simulation computing device (FPGA) is 10µs, then the maximum data sampling frequency is 100kHz. In this embodiment, based on the global data acquisition device, the waveform sampling frequency of the FPGA is "decoupled" from the control of the data interaction step size. The waveform sampling frequency of the FPGA is only controlled by its own simulation calculation step size. That is, if the calculation step size of the small-step simulation calculation device is 1µs, then the waveform sampling frequency is 1000kHz. The global data acquisition device, as a supplement to the output module of the small-step simulation calculation device, avoids the inability to accurately observe waveform anomalies within a single interaction step size during calculation, thus preventing abnormalities in the power grid system analysis.

[0029] In some embodiments, the feature is that the full-domain data acquisition device supports file output to Windows and Linux systems, and outputs the real-time electromagnetic transient simulation results acquired in real time across the entire time domain within the target output time period, provided that the target output time period is determined by the host computer or user terminal.

[0030] It should be noted that the full-domain data acquisition device is equipped with a high-performance FPGA processing unit. It communicates with the small-step simulation calculation device via fiber optic cable to acquire the simulation calculation results for each step. It supports file output to both Windows and Linux systems. The target time period for output is determined by the host computer / user terminal. If sufficient memory is available, full-time domain output is possible. Based on user-configured parameters, the host computer can output the required memory amount. After configuring the full-domain data acquisition device, the required memory amount will be returned, providing further feedback to the user on memory sufficiency. Furthermore, the host computer / user terminal allows for specific vector observation configurations of the full-domain data acquisition device, such as observing a single variable or configuring the observation time period, preventing data overwriting due to memory overload.

[0031] In some embodiments, the data processing device receives simulation tasks from a host computer or user terminal to perform topology analysis on the electromagnetic transient simulation results, forming simulation calculation data; then, it performs standardized analysis on the simulation calculation data to obtain simulation analysis results, and displays the simulation analysis results to the host computer or user terminal. Specifically, Figure 2 This is a flowchart illustrating the steps of operating a data processing apparatus according to an embodiment of this application, such as... Figure 2 As shown, it includes the following steps: Step (1): Initialize parameters, read data and send parameters, and send the data collection time period [T1, T2]; Step (2): Time domain judgment. If the simulation time is in [T1, T2], the small step size simulation calculation will output and store data for all steps. The storage format is "frame header + voltage data + current data". If it is not in this time period, it means that the data acquisition is over. Step (3) Data parsing: After the data acquisition is completed, data parsing is performed. The data format is double-precision floating-point number, which needs to be parsed into the decimal number corresponding to each component according to the format of "frame header + voltage data + current data". Step (4) Waveform drawing: After parsing the data for each step, draw the data into a waveform in the format of increasing time.

[0032] It should be noted that the data processing device is equipped with a high-performance CPU processing unit, and includes integrated circuits such as large-capacity high-speed memory and large-capacity solid-state drives that support high-speed read and write, which can cache data for a long time. In addition, (1) it has a built-in electromagnetic transient simulation processing system, which receives simulation tasks and data interaction instructions issued by the host computer / user terminal, performs calculation topology analysis on the electromagnetic transient simulation results, and forms simulation calculation data; (2) it is equipped with a data parsing system, which performs standardized parsing on the simulation calculation data and forms tables or waveforms to be displayed to the host computer / user terminal; (3) it has a visual operating system, which can perform visual parsing on the data. The host computer / user terminal builds the simulation tasks and models into APP application form based on the visual operating system, and the system combines data and application to display intuitive waveforms to the host computer / user terminal.
