[0059] OPAL-RT real-time simulator: OPAL-RT's real-time simulator is widely used in the development and testing of power electronics, energy systems, and control systems. Its system can run large-scale physical models in real time through the combination of high-performance computing hardware and simulation software, thereby realizing hardware-in-the-loop and software-in-the-loop (SIL, Software-in-the-Loop) simulation. OPAL-RT is a company that provides real-time simulation and hardware-in-the-loop (HIL, Hardware-in-the-Loop) solutions, focusing on real-time simulation of complex systems such as power systems, autonomous driving, aerospace, etc.

[0060] RT-LAB real-time simulation management software: It is a software product of OPAL-RT, the same as the OPAL-RT real-time simulator. As the host software of the OPAL-RT real-time simulator, RT-LAB is integrated with MATLAB / Simulink to provide users with a seamless distributed computing execution platform for real-time synchronization, user interface, real-time hardware interface and data interaction.

Its main functions and features include Internet stack models (TCP, UDP, IPv4, IPv6, OSPF, BGP, etc.), wired and wireless link layer protocols (Ethernet, PPP, IEEE 802.11, etc.), INET also contains some high-level application protocol models that can help simulate the traffic behavior of actual network applications, such as HTTP, FTP, etc.

[0063] DPDK (Data Plane Development Kit): Developed by 6WIND, Intel and other companies, it is a collection of function libraries and drivers for fast data packet processing, which can greatly improve data processing performance and throughput, and improve the efficiency of data plane applications.

[0064] Figure 1 FIG. 1 is a schematic diagram of the architecture of the power simulation data interaction system of the present invention, wherein NIC1 ... NIC4 are physical network interfaces, Node1 ... Noden are virtual nodes, such as Figure 2As shown, the present invention provides a power simulation data interaction system, including a power system simulation module 101, a communication network simulation module 102 and a power system monitoring module 103 which are communicatively connected in sequence.

[0065] Specifically, the power system simulation module 101 is used to configure the system parameters of the power cyber-physical system to construct a power cyber-physical system model, referred to as the power system model, and to perform real-time simulation on the power system model to obtain simulation data corresponding to the current operating state;

[0066] In one possible implementation, the power system simulation module 101 also includes a model building unit, which is used to configure system parameters to build a power system model; a real-time simulation unit, which is used to simulate the power system model in real time to obtain simulation data corresponding to the current operating status; and a physical network interface, which is used to send simulation data or receive control instructions.

[0067] As an example, a technician in this field can choose to arbitrarily configure the system parameters, and then obtain key components in the power system such as generators, transformers, transmission lines and loads from any existing component library, and then build a power system model through platforms such as MATLAB / Simulink to simulate the current operating status of the power system; system parameters include the rated power of the generator, voltage level, capacity of the transformer, length and impedance of the line and other parameters.

[0068] As an example, the RT-LAB real-time simulation platform is used as a real-time simulation unit, which is responsible for executing real-time simulation of the power system model, obtaining simulation data corresponding to the current operating state of the simulated power system, and then outputting it to the physical network interface through the IO module or IOInterface function.

[0069] Specifically, the communication network simulation module 102 is used to configure simulation network parameters, obtain a simulated communication network environment, make simulation data or control instructions pass through the simulated communication network environment, obtain simulation data packets, and parse the simulation data packets to obtain network simulation data or control instructions.

[0070] In a possible implementation, the communication network simulation module 102 further includes:

[0071] Several physical network interfaces, used for receiving simulation data sent by the power system simulation module and control instructions sent by the power system monitoring module, and sending network simulation data to the power system monitoring module or sending control instructions to the power system simulation module;

[0072] A DPDK data conversion unit is used to parse the simulation data or control instructions to convert the simulation data or control instructions to obtain communication network data packets, and to parse the simulation data packets to obtain network simulation data or control instructions;

[0073] The communication network model is used to configure simulation network parameters to construct a communication network model, thereby simulating the communication network environment, allowing the communication network data packets to experience the simulated communication network environment to obtain simulated data packets.

[0074] As an example, before configuring the simulation network parameters, it is optional to configure the simulation network parameters based on network simulation software such as OPNET or OMNet++ to build an initial communication network model.

[0075] In a possible implementation, the DPDK data conversion unit includes:

[0076] Initialization element, used to initialize the operating environment, memory buffer, memory pool and data port;

[0077] Data port, used to receive or send data;

[0078] Memory buffers and memory pools for storing data received by the data ports;

[0079] The data processing element is used to convert simulation data or control instructions into communication network data packets, or to parse simulation data packets to obtain network simulation data or control instructions.

[0080] As an example, the DPDK data conversion unit adopts polling mode instead of interrupt-driven mode. In polling mode, the packet processing thread continuously checks whether new data packets have arrived at the network interface instead of waiting for interrupt signals, so as to reduce the interrupt processing overhead and control the processing of data packets in a more fine-grained manner.

[0081] As an example, the DPDK data conversion unit runs in user space and directly accesses the network interface through user space, avoiding frequent switching between kernel space and user space, so DPDK applications can interact directly with the hardware without making system calls.

[0082] As an example, the DPDK data conversion unit uses large page memory allocation and ring buffers to manage data packets. When a data packet arrives, it is directly stored in the large page memory without the need to copy it from kernel space to user space. This zero-copy technology reduces the consumption of CPU cycles and the pressure on memory bandwidth.

[0083] As an example, the buffer management in the DPDK data conversion unit adopts a lock-free design, which can reduce lock contention and context switching overhead when processing packets in a multi-threaded environment.

[0084] As an example, the DPDK data conversion unit supports the non-uniform memory access (NUMA) architecture, allowing packet processing threads to prioritize access to local memory, reducing the latency of accessing memory across nodes.

[0085] As an example, the DPDK data conversion unit loads the user space I / O (UIO) driver so that the DPDK data conversion unit can interact directly with the network interface card in user space, bypassing the kernel network stack to improve the performance of packet processing and further reduce the data processing time in kernel space.

[0086] As an example, the DPDK data conversion unit provides a series of high-performance libraries, such as rte_memcpy(), which use the SIMD instruction set of modern CPUs to accelerate memory operations and further improve performance.

[0087] In a possible implementation, the initialization unit includes:

[0088] The environment abstraction layer is used to set parameters according to the function rte_eal_init to initialize the operating environment;

[0089] The memory initialization component is used to initialize the memory buffer and memory pool queue according to the function init_mbuf_pools;

[0090] The data port initialization component is used to initialize the port configuration according to the function init_port, set the port attributes according to the function rte_eth_dev_configure, start the port sending and receiving queues according to the function rte_eth_rx / tx_queue_setup, activate the port work according to the function rte_eth_dev_start, and set the callback function to send and receive data.

[0091] In a possible implementation, the data processing element includes:

[0092] A data parsing component is used to parse simulation data to obtain pointers to protocol data structures at each layer of simulation data, or to parse simulation data packets to obtain network simulation data or control instructions;

[0093] A data conversion component is used to convert the protocol data structure pointers or control instructions of each layer of simulation data to obtain communication network data packets, or convert simulation data packets to obtain network simulation data or control instructions according to the prior communication network data packet format;

[0094] The data transmission component is used to transmit control instructions or network simulation data to the data port.

[0095] As an example, since DPDK technology supports standard network protocol stack data packet parsing, it is possible to optionally obtain pointers to protocol data structures at each layer of the data packet through the corresponding interface; preferably, if the data packet contains a custom protocol header, a technician in this field can optionally customize and develop parsing logic according to actual needs to identify the custom protocol header.

[0096] As an example, the data conversion component converts the parsed data packet into a priori communication network data packet format according to the structure definition of the simulation data, and finally transmits the communication network data packet to the network port through the ring buffer queue.

[0097] In a possible implementation, the communication network model includes:

[0098] A network parameter configuration unit, used to configure the simulation network parameters of each virtual node;

[0099] Several virtual nodes are used to simulate each network node in the communication network environment.

[0100] As an example, each virtual node is mapped to each physical network interface one by one, and mapping configuration information is set for the corresponding virtual node according to the physical network interface to ensure that the data received from the physical network interface can be correctly transmitted to the corresponding virtual node, and the data sent from the virtual node can be sent out through the correct physical network interface, and ensure that the DPDK data conversion module can convert the received data into the correct format; mapping configuration information includes information such as port name, IP and data interaction protocol definition. Among them, the port name and IP address are used to identify the physical port and virtual node, and the data interaction protocol definition specifies the structure and transmission rules of the data packet to ensure that the DPDK data conversion unit correctly processes and converts the data packet.

[0101] Specifically, the power system monitoring module 103 is used to display the operating status of the power system model according to the network simulation data, and send control instructions to the power system simulation module to change system parameters.

[0102] In a possible implementation, the power system monitoring module 103 includes:

[0103] A physical network interface, used to receive network simulation data sent by the communication network simulation module and send control instructions;

[0104] The analysis unit is used to analyze all received network simulation data and generate data reports, trend charts and fault reports; it is worth noting that data reports, trend charts and fault reports are only a form of data presentation, and can also be presented as any chart such as bar charts, bar charts and area charts, but is not limited to this.

[0105] A display unit is used to display the operating status of the power system model, as well as current system parameters, data reports and trend graphs based on network simulation data;

[0106] A monitoring unit, used to record the operating status and fault reports of the power system model;

[0107] The early warning unit is used to determine whether the network simulation data is greater than the alarm threshold according to the set alarm threshold. If not, it remains unchanged. If so, it notifies the scheduled staff;

[0108] The control unit is used to input control instructions to the power system model.

[0109] As an example, each data in the network simulation data is set with a corresponding alarm threshold, such as a voltage threshold, a current threshold, a power threshold, and a frequency threshold.

[0110] As an example, the early warning unit pre-binds several staff members, and then determines in real time whether the received network simulation data is greater than the corresponding set alarm threshold. If not, it remains unchanged. If so, the predetermined staff members can be notified through any communication method such as SMS, email and phone.

[0111] In this embodiment, a power simulation data interaction system of the present invention is provided. The system parameters are configured through the power system simulation module to construct a power system model, and the power system model is simulated in real time to obtain simulation data corresponding to the current operating state. Then, the simulation network parameters are configured through the communication network simulation module to obtain a simulated communication network environment, so that the simulation data or control instructions are subjected to the simulated communication network environment to obtain a simulated data packet, and the simulated data packet is parsed to obtain network simulation data or control instructions, thereby improving the data packet processing speed and reducing the delay of data interaction. Finally, the operating state of the power system model is displayed according to the network simulation data through the power system monitoring module, and control instructions are sent to the power system simulation module to change the system parameters to obtain the operating state of the power system under different system parameters. The problem that the existing technology cannot effectively collect, store and analyze simulation data in a timely manner is solved.

[0112] On the other hand, the present invention further provides a method for interacting with power simulation data.
