Description

Technical Field

[0001] This utility model relates to the field of substation automation technology, and in particular to a substation information automatic commissioning and acceptance device. Background Technology

[0002] With the continuous advancement of smart grid construction and the increasing informatization level of substations, the complexity and workload of substation information integration and acceptance testing have also increased. Substation information integration and acceptance testing is a crucial step in ensuring the normal operation of substation automation systems. Its main task is to verify the normality of communication and data exchange between various information systems within the substation, including the transmission and processing of information such as MMS messages and 104 protocol messages. MMS messages are the manufacturing message specifications in substation automation systems, and 104 protocol messages are the power system remote control protocol. These two types of messages contain important information such as the operating status and measured values ​​of substation equipment.

[0003] Currently, substation information integration and acceptance testing mainly adopts manual point-to-point verification or processor-based automated acceptance systems. Manual point-to-point verification requires staff to check information points one by one on-site, which is labor-intensive, inefficient, and prone to errors, making it difficult to meet the needs of large-scale substation information integration and acceptance testing.

[0004] Processor-based automated acceptance systems improve acceptance efficiency. For example, CN209690901U discloses a portable process layer message analysis device for substations. The device includes a body and a display cover. The body contains a CPU and a process layer message input board, which can realize online monitoring of process layer messages at the substation site. However, it lacks efficient multi-channel data monitoring and processing capabilities, making it difficult to simultaneously monitor and analyze MMS messages and 104 protocol messages, resulting in low acceptance efficiency for substation information commissioning.

[0086] Specifically, the display device is a 10.1-inch high-definition touchscreen with a resolution of 1920×1080 pixels and a brightness of 350 nits. It uses capacitive touch technology and supports multi-touch operation. The display device is connected to the development board via an HDMI interface and is used to display information such as system operating status and message data analysis results. In this embodiment, the display device can be a touch screen or a non-touch screen, configured according to the actual situation.

[0087] Specifically, in the workbench, the power input interface is a standard AC220V three-hole socket, supporting national standard power cord connection; the power control switch is a rocker switch with indicator lights, used to control the power supply of the entire device; the message transmission / time synchronization signal input interface is a GBE interface, used to connect to the substation network; the grounding wire socket is a standard grounding terminal, used to connect the device's grounding protection wire; the human-machine input device is a keyboard, keyboard and mouse kit or keyboard-touchpad kit, which connects to the development board through corresponding interfaces such as USB3.0 Type-A interface and USB3.0 Type-C interface.

[0090] The development board connects to the message transmission / time synchronization signal input interface via a data monitoring channel to monitor MMS messages and 104 protocol messages. The data monitoring channel consists of a high-speed data acquisition circuit using a dedicated network data processing chip, supporting gigabit Ethernet data transmission and capable of capturing network message data in real time. The data monitoring channel connects to the development board via high-speed PCB traces to ensure data transmission stability and real-time performance.

Both types of messages contain important information such as the operating status and measured values ​​of substation equipment.

[0091] The development board connects to the message transmission / time synchronization signal input interface via a time synchronization channel to receive time synchronization signals. The time synchronization channel consists of a precision clock synchronization circuit, supporting the IEEE 1588 precision clock synchronization protocol with microsecond-level time accuracy.

After the device starts, the display device shows the system interface, and the operator operates it through the human-machine interface. The device automatically listens for MMS messages and 104 protocol messages in the substation network and receives time synchronization signals to maintain clock synchronization. The system parses, analyzes, and verifies the collected message data to determine whether the operating status of the substation information system meets the requirements, and finally generates a commissioning and acceptance report, which is displayed on the display device, helping engineers quickly complete the commissioning and acceptance work of the substation information system.

[0093] Based on the above embodiments, in this embodiment, in order to simultaneously monitor MMS messages and 104 protocol messages, a typical implementation of the message transmission / time synchronization signal input interface is provided, including:

[0094] The development board is equipped with 4 PCIe 3.0 interfaces and 2 RGMII interfaces. Each PCIe 3.0 interface provides one GBE port through a PCIe to Gigabit Ethernet expansion card, and each RGMII interface is converted into one GBE port through a PHY chip. In other words, the 4 PCIe 3.0 interfaces and 2 RGMII interfaces on the development board are converted into 6 GBE ports, which are used as message transmission / time synchronization signal input interfaces.

[0095] Each PCIe 3.0 interface is connected to a PCIe-to-Gigabit Ethernet expansion card via PCB traces, which then connects to one GBE port. The PCIe-to-Gigabit Ethernet expansion card uses an Intel I210 or I211 series Gigabit Ethernet chip, supports the IEEE 802.3 standard, and provides a network transmission rate of 1000Mbps.

[0096] Each RGMII interface is connected to a PHY chip via PCB traces, and then to a GBE port. The PHY chip uses a Realtek RTL8211F or equivalent chip, supporting 10 / 100 / 1000Mbps adaptive network speeds. The RGMII interface is a simplified gigabit media-independent interface, providing 12 signal lines per interface, including transmit data lines, receive data lines, clock lines, and control lines.

[0097] In this embodiment, the development board's four PCIe 3.0 interfaces and two RGMII interfaces are converted into six GBE ports. These ports serve as message transmission / time synchronization signal input interfaces, used to connect to the data gateway's egress switch to monitor and acquire 104 protocol message data from the scheduling data network, and to connect to the station control layer switch to monitor and acquire MMS message data. The six GBE ports can simultaneously monitor multiple network nodes, improving the device's data acquisition capabilities and operational efficiency.

[0098] Specifically, the connection method between the GBE ports and the substation switches is as follows: four of the six GBE ports are connected to the ports of the data gateway's output-side switch, respectively accessing the 104 Backup B network, 104 Backup A network, 104 Main B network, and 104 Main A network for 104 protocol message data monitoring and acquisition; the other two GBE ports are connected to the ports of the station control layer switch, respectively accessing the MMSB network and MMS A network for MMS message data monitoring and acquisition.

[0101] Specifically, the connection method between the GBE ports and the substation switches is as follows: four of the six GBE ports are connected to the ports of the data gateway's output-side switch, respectively accessing the 104 Backup B network, 104 Backup A network, 104 Main B network, and 104 Main A network for 104 protocol message data monitoring and acquisition; the other two GBE ports are connected to the ports of the station control layer switch, respectively accessing the MMSB network and MMS A network for MMS message data monitoring and acquisition. This configuration enables the device to simultaneously monitor communication data at different levels of the substation, comprehensively grasping the operational status of the substation information system. Furthermore, this embodiment uses the PCIe interface entirely for network connection, offering higher scalability and compatibility, while simplifying system design and improving monitoring reliability.

[0102] Based on the above embodiments, in this embodiment, in order to simultaneously monitor MMS messages and 104 protocol messages, a typical implementation of the message transmission / time synchronization signal input interface is provided, including:

[0103] The development board has two PCIe 3.0 interfaces. Each PCIe 3.0 interface is expanded into four PCIe 3.0 interfaces through a PCIe bus connected to a PCIe multi-port switch chip. Each of these is then connected to a Gigabit Ethernet card, forming four GBE ports. In other words, the two PCIe 3.0 interfaces on the development board are converted into eight GBE ports, used as message transmission / time synchronization signal input interfaces. The PCIe multi-port switch chip can be a PLX PCIe multi-port switch chip, such as the PEX8608 or PEX8609 series.

[0104] PLX's PCIe multi-port switch chip supports the PCIe 3.0 standard, with a unidirectional bandwidth of up to 8GT / s and supports up to 192 virtual channels to meet the needs of complex systems. It also has a built-in DMA engine to reduce the burden on the main processor. In addition, it supports hot-swapping, which improves system flexibility. Its low-power design has a typical power consumption of only 2.5W.

[0105] PCIe multi-port switches are high-performance PCIe switching chips that support the PCIe 3.0 standard and feature low latency and high bandwidth. Each PCIe multi-port switch expands one PCIe 3.0 interface into four, thus increasing the number of interfaces. Each expanded PCIe 3.0 interface connects to a Gigabit Ethernet controller chip, such as the Intel I210 or I211 series, and then to a GBE port. Through this design, the development board's two PCIe 3.0 interfaces are expanded by the PCIe multi-port switch and ultimately converted into eight GBE ports.

[0106] Specifically, the connection method between the GBE ports and the substation switches is as follows: Four of the eight GBE ports are connected to the ports of the data gateway's output-side switch, respectively accessing the 104 Backup B network, 104 Backup A network, 104 Main B network, and 104 Main A network for 104 protocol message data monitoring and acquisition; the other two GBE ports are connected to the ports of the station control layer switch, respectively accessing the MMS B network and MMS A network for MMS message data monitoring and acquisition. This configuration enables the device to simultaneously monitor communication data at different levels of the substation, providing a comprehensive understanding of the substation's information system operation status.

[0107] Based on the above embodiments, in this embodiment, in order to simultaneously monitor MMS messages and 104 protocol messages, a typical implementation of the message transmission / time synchronization signal input interface is provided, including:

[0108] The development board is equipped with two RGMII interfaces. Each RGMII interface is expanded to have at least three GBE ports through one RGMII switching chip. That is, the two RGMII interfaces on the development board are expanded to at least six GBE ports, which are used as message transmission / time synchronization signal input interfaces.

[0109] Each RGMII interface is connected to one RGMII switch chip via high-quality PCB traces. The RGMII switch chip is a high-performance Ethernet switch chip, such as the YT8531 series or YT9215 series, supporting the IEEE 802.3 standard and featuring low latency and low power consumption. The YT8531 series chip supports 5 ports, with one uplink port connected to the RGMII interface on the development board, and four downlink ports converted to GBE ports via a PHY chip. The YT9215 series chip supports 6 ports, with one uplink port connected to the RGMII interface on the development board, and five downlink ports converted to GBE ports via a PHY chip.

[0110] Therefore, the two RGMII interfaces on the development board are expanded into at least six GBE ports after being extended by the RGMII switching chip; eight GBE ports are used when using the YT8531 series chips, and ten GBE ports are used when using the YT9215 series chips.

[0111] Specifically, the connection method between the GBE ports and the substation switches is as follows: Four GBE ports are connected to the ports of the data gateway's output-side switch, respectively accessing the 104 Backup B network, 104 Backup A network, 104 Main B network, and 104 Main A network for 104 protocol message data monitoring and acquisition; the other two GBE ports are connected to the ports of the station control layer switch, respectively accessing the MMS B network and MMS A network for MMS message data monitoring and acquisition. This configuration enables the device to simultaneously monitor communication data at different levels of the substation, providing a comprehensive understanding of the substation's information system operation status.
