For easy understanding, reference may be made to fig. 1, which is a diagram illustrating a typical network structure of a 110kV intelligent substation in the prior art. At present, an intelligent transformer substation generally consists of a three-layer two-network communication structure, namely a master control system consists of three layers of equipment, namely a station control layer, a spacer layer and a process layer, a data transmission network is formed by a large number of station control layer network switches and process layer network switches to transmit four-remote signals between the three layers of equipment, and as long as the switches break down, the reliability of the network is influenced, so that the communication of the four-remote signals is influenced, and finally, the safe, reliable and stable operation of the transformer substation is directly influenced. As shown in fig. 1, a process layer network needs to construct four redundant networks, i.e., A1, A2, B1, and B2, a station control layer needs to construct four redundant networks, i.e., A, B, C and C2, each network is configured with 2 switches for calculation, 16 switches are needed for a total station, and the network structure is very complex. Meanwhile, the secondary devices include but are not limited to merging units, intelligent terminals, protection devices, measurement and control devices, fault recorders, process layer switches, station control layer switches, remote machines, background monitoring hosts, five-prevention hosts and the like. In terms of quantity, the substation master control system is configured with secondary devices according to outgoing line intervals, the quantity of the substation secondary devices is different from dozens of secondary devices to hundreds of secondary devices according to the difference of voltage level and the quantity of the outgoing line intervals, and the workload of maintaining the secondary devices is expected to be very large. According to the knowledge, the largest workload of operation and maintenance staff of the transformer substation is the defect eliminating work of a secondary device, and the main defects to be processed include device clamping piece damage, communication abnormity, display screen faults and the like. According to the system reliability theory, the more nodes and links forming a system, the lower the reliability of the system, so that the reliable operation of the transformer substation master control system can be ensured only by eliminating defects within a limited time by operation maintainers at present, and the workload is very large and the efficiency is not high. As shown in fig. 1, taking a 110kV intelligent substation as an example, on the premise of not considering the number of outgoing line intervals, about 50 secondary devices are required besides a network switch, and the workload of operation and maintenance of a courseware substation is relatively large.

Specifically, the embedded high bandwidth switching communication Network may be a Controller Area Network (CAN) Bus, an Internet Protocol (IP) Bus, a Modbus Bus, a Process Field Bus (Profibus), a Highway Addressable Remote Transducer (HART) Bus, an FF Field Bus, or an optical fiber. Further, in the preferred embodiment, the intelligence integration device 200 of the present application is connected to the main control unit 100 through an optical fiber. Therefore, in the substation master control system provided by the application, the intelligent integrated device 200 is connected with the master control unit 100 through optical fibers, the existing three-layer two-network communication architecture is simplified into two-layer no-network communication architecture, a network switch is omitted in the substation, the communication between the master control unit 100 and the intelligent integrated device 200 is realized through a mode of directly connecting the optical fibers, intermediate links of data transmission of the substation are reduced, the network communication architecture of the master control system is simplified, and the reliability of the communication of the whole substation is improved.

At present, in the prior art, a device and a system of a substation main control system are both deployed in a security zone I, and an online monitoring system and a sensor are deployed in a security zone II, that is, a main control unit, an intelligent integration device, primary equipment and the like belong to different network partitions. Therefore, the interaction between the online monitoring data and the monitoring system data is isolated by the transverse firewall, so that the data sharing and utilization rate is not high, and the quality of online monitoring and state evaluation of the primary equipment of the transformer substation is directly influenced. To solve this technical problem, the intelligent integrated device 200 and the master control unit 100 are both accessed in the same network security zone. Referring specifically to fig. 3, in a preferred embodiment, the intelligent integrated device 200 and the master control unit 100 are deployed in the security zone I, which is equivalent to eliminating the security zone II.

In one embodiment, the intelligence integration apparatus 200 is mounted in the vicinity of the electrically isolated primary device 210 at intervals, and is connected to the primary device 210 by a cable; the primary device 210 is configured to perform power generation, power transmission, and power distribution functions according to the control message; a sensor 220 is further disposed near the primary device 210, and the sensor 220 is connected to the intelligent integrated device 200 through a cable for collecting electrical parameters.

In an embodiment, the second structure of the substation master control system provided in the present application may include a master control unit 100 and a plurality of intelligent integrated devices 200, as shown in fig. 4, including an intelligent integrated device 1, an intelligent integrated device 2, and an intelligent integrated device n. Each of the plurality of intelligent integrated devices 200 is preferably connected to the main control unit 100 by an optical fiber. The intelligent integrated device 200 further comprises a primary device 210 and a sensor 220, and the intelligent integrated device 200 is connected with the primary device 210 and the sensor 220 through cables.

In one embodiment, the primary device 210 may be understood as a device performing power generation-transmission-distribution functions, and may specifically include, but is not limited to, devices such as a generator, a transformer, a current transformer, a voltage transformer, an operation box, and a switch. Meanwhile, the sensor 220 may be used to collect some scattered electrical parameters, such as temperature, humidity, pressure, etc., so as to send back to the main control unit 100 through the intelligent integrated device 200 for monitoring. Based on this, through a plurality of integrative devices 200 that cooperate intelligence interval installation near electrical spaced primary equipment 210 to through the mode that cable and primary equipment 210 are connected, under the circumstances that guarantees the realization of transformer substation's supervisory control function, greatly reduced the type and the quantity of secondary equipment in the master control system, reduced the probability that leads to the unreliable operation of transformer substation because of equipment failure, reduced the work load that transformer substation operation maintainer maintained equipment. Compared with the existing substation main control system, the operation and maintenance personnel only need to pay attention to two types of equipment, namely the main control unit 100 and the intelligent integrated device 200 when maintaining.

In one embodiment, the master control unit 100 includes: the intelligent integrated device comprises a first main control unit 110 and at least one second main control unit 120, wherein the first main control unit 110 and the second main control unit 120 are connected through optical fibers, and the intelligent integrated device 200 is respectively connected with the first main control unit 110 and each second main control unit 120; the first master control unit 110 includes a first monitoring module, and the second master control unit 120 includes a second monitoring module, where the first monitoring module is used to monitor the operating state of the second master control unit 120; the second monitoring module is used to monitor the operation state of the first main control unit 110.

In an embodiment, the master control unit 100 may be further divided into a first master control unit 110 and a second master control unit 120, wherein the relationship between the first master control unit 110 and the second master control unit 120 may also be understood as a primary-standby relationship. In the preferred embodiment, therefore, the first master control unit 110 and the second master control unit 120 also have data collection and processing functions, so that all the intelligent integrated devices 200 in the system also need to be connected to the first master control unit 110 and the second master control unit 120 respectively. In addition, since the relationship between the first master control unit 110 and the second master control unit 120 is a primary-backup relationship, in a preferred embodiment, the number of the first master control unit 110 is one, and the number of the second master control unit 120 may be multiple. Further, the two types of devices are preferably connected by means of optical fibers, so that data communication between the two types of devices is ensured under a netless structure. Specifically, as to the structure of the substation system provided in this embodiment, reference may be made to fig. 5, where fig. 5 is a schematic diagram of a third structure of a substation main control system in one embodiment. It can be understood that the third structure of the substation master control system provided in this embodiment also belongs to a simplified structure of "two-layer no network", and the communication between the master control unit 100 and the intelligent integrated device 200 and between the first master control unit 110 and the second master control unit 120 is realized by directly connecting optical fibers, so that intermediate links of data transmission of a substation are reduced, and the reliability of the communication of the whole substation is improved.

In an embodiment, the data flow between the first master control unit 110 and the second master control unit 120 may be mainly used for monitoring the operation status of each other, and therefore, a monitoring module is respectively included between the two. The first main control unit 110 includes a first monitoring module, and the second main control unit 120 includes a second monitoring module, the first monitoring module is used for monitoring the operation state of the second main control unit 120; the second monitoring module is used to monitor the operation state of the first main control unit 110. Specifically, since the two are in a primary-standby relationship, in a preferred embodiment, both the first main control unit 110 and the second main control unit 120 keep the data acquisition and processing functions under normal conditions, but only the first main control unit 110 has the control right. That is, the main control unit 100 further has control modules, wherein the first main control unit 110 includes a first control module, and the second main control unit 120 includes a second control module. As mentioned above, the relationship between the first master control unit 110 and the second master control unit 120 is the primary-standby relationship, and the relationship of the number of the first master control unit 110 and the second master control unit 120 is that there is one first master control unit 110 and at least one second master control unit 120 in the substation master control system. Therefore, the distinction between the first master control unit 110 and the second master control unit 120 is only a functional distinction, and there is no difference in structure between the two, that is, it can be understood that at least two master control units 100 may be included in the substation master control system, where one master control unit having a control right is the first master control unit 110, and the remaining other master control units 100 are the second master control units 120. And the concrete expression of possessing the control right is as follows: when the first main control unit 110 is determined to operate normally according to the second monitoring module, the first control module is started, and the second control module is stopped; when it is determined that the first main control unit 110 operates abnormally according to the second monitoring module, the first control module is deactivated and the second control module is activated. That is, only one of the control modules is started according to the monitoring of the monitoring module, or it is ensured that one main control unit 100 always has the control right in the operation process of the substation system, so that the functions of the main control unit 100 described above are realized, and the high-reliability uninterrupted operation of the substation main control system is ensured.

In the present application, since the secondary device is only the main control unit 100 and the intelligent integrated apparatus 200, the system is simplified, and the number of the indoor cubicles 70 of the main control system is reduced. If there are two types of master control units 100, namely, a first master control unit 110 and a second master control unit 120, according to an embodiment of the present application, the transformer substation master control system cubicle arrangement of the present application can refer to fig. 7. As can be seen from comparison between fig. 6 and fig. 7, the screen cabinet 70 of the substation master control system provided by the present application only needs one screen, which is much smaller than the number of screen cabinets in the typical configuration of the current intelligent substation, and the reduction of the area required for placing the screen cabinet 70 can reduce the floor area of the substation and save the investment.
