[0036] In order to be able to more clearly understand the above-described objects, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0037] Many specific details are described in the following description to facilitate a full understanding of the present invention, however, the present invention may also be implemented in a manner different from those described herein, therefore, the present invention is not limited to the limitations of specific embodiments of the following disclosure statement.
[0038] An intelligent substation integration information platform of the present embodiment, with reference Figure 1-3 : Including the first and second security zones, there is an isolation module on the communication link between the first security zone and the second security zone.
[0039] Isolation module includes a forward isolation device and a reverse isolation device, the forward isolation device data transmission direction is the first safety zone to the second safety zone, the reverse isolation device data transmission direction is the second security zone to the first security zone.
[0040] Wherein, the isolation device module is used for the safe transmission of data information between the first and second security zones.
[0041] The functions of the forward isolation device include, but are not limited to: (1) to achieve a secure data exchange in a non-network mode between the first and second security zones, and to ensure that the two processing systems inside and outside the security isolation device do not communicate at the same time; (2) the working mode is transparent and the host IP address is virtual and the MAC address is hidden; (3) comprehensive packet filtering and access control based on MAC, IP, transmission protocol, transmission port and communication direction; (4) support FOR NAT; (5) prevent penetrating TCP connection: prohibit intranet, A TCP connection is established directly between the two application gateways of the extranet, and the two NICs inside and outside the isolated device are non-network connected inside the device, and only allow one-way transmission of data and data in a physical way.
[0042] In addition to the functions of the reverse isolation device, the reverse isolation device has the functions of the forward isolation device, but also has: (1) the data transmitter in the second security zone first signs the data to be sent, and then sends it to the reverse isolation device; (2) after the reverse isolation device receives the data, it performs signature verification, and performs content filtering, validity checking, etc.; (3) the reverse isolation device forwards the processed data to the receiving program inside the first security zone.
[0043] The first security zone is equipped with a central control system, a video surveillance subsystem, a three-dimensional animation model subsystem, and a black box subsystem.
[0044] (1) The central control system is used to collect the status information of all subsystems and equipment in the substation, and the central control system is also used to dispatch the working status of all subsystems and equipment in the substation.
[0045] The central control system is installed in the server in the central control room, and the central control system of different substations is shared through the blockchain, which is because the blockchain has high security (the blockchain adopts a decentralized distributed recording method, each node in the system participates in the data change record at the same time, each node retains an identical and complete data sample, and the destruction of a single node will not affect the integrity of the entire sample and record, which greatly improves the security of the data), high transparency (the public blockchain system is open, Maintained by all the nodes with maintenance functions, in addition to the private information of the parties to the transaction is encrypted, anyone can query the blockchain data and develop related applications through the public interface, so the information of the entire system is highly transparent. ), high autonomy (blockchain adopts consensus-based norms and protocols (such as a set of established algorithms), allowing participants to conduct free and secure transactions in an environment that does not require trust in anyone, evolving from trust in "people" in the past to trust in machine "algorithms", eliminating human interference to achieve a high degree of autonomy) and immutability (once the information is verified and added to the blockchain, it will be permanently stored, generating data records that are marked in chronological order and are difficult to tamper with, It can not only ensure the traceability of data, but also greatly reduce the situation of data fraud at different nodes at different points in time) and other advantages.
[0046] (2) The video surveillance subsystem is embedded in the central control system, the video surveillance subsystem includes the camera installed at each point in the substation and the first display screen set in the central control room, the first display screen real-time display camera to shoot the picture.
[0047] It is worth noting that the first display is composed of several displays; all corners in the substation are monitored by the video surveillance subsystem.
[0048] (3) The three-dimensional animation model subsystem is embedded in the central control system, and the three-dimensional animation model subsystem is output on the second display screen in the central control room.
[0049] It is worth noting that the construction of the 3D animation model subsystem is based on the real structure of the substation to one to the real, and the substation model state output by the 3D animation model subsystem on the second display is the same as the real state of the substation. In this way, the staff in the substation can clearly and intuitively understand the working status of each subsystem and equipment through the three-dimensional animation model of the substation output on the second display.
[0050] (4) The black box system is embedded in the central control system, and the black box system records the status information of all systems and equipment in the substation in real time and records the operation steps of the power station staff in real time. In this way, O&M managers can analyze the data recorded in the black box system to trace the cause of the failure, so that targeted improvements can be made at a later stage.
[0051] The second safety zone is equipped with fire subsystem, environmental monitoring subsystem, inspection subsystem, equipment status acquisition subsystem and security subsystem.
[0052] (1) The fire subsystem collects the alarm point information, fault information, self-inspection information, operating conditions and action information of fire extinguishing equipment of each fire fighting equipment in real time.
[0053] Because the fire subsystem in the present invention has a self-test function, so that the staff does not need on-site inspection but in the central control room real-time centralized view, greatly reducing labor costs and greatly improving the content and frequency of operation and maintenance.
[0054] (2) The data objects collected by the environmental monitoring subsystem include micro-meteorological data such as outdoor temperature, humidity, rainfall, wind speed, and wind direction, as well as indoor temperature, humidity, water immersion status of cable trenches, and water level of catchment wells.
[0055] In this way, the central control system can detect the environmental conditions around the substation through the environmental detection subsystem, so as to decide whether it is necessary to start the air conditioning, fans, dryers and other equipment in the substation, so as to ensure the safe operation of the equipment in the substation.
[0056] (3) The inspection subsystem is an intelligent robot driving in the substation, and wireless communication is achieved through a safe channel between the intelligent robot and the central control system.
[0057] It is worth noting that the intelligent robot has the function of freely switching trackless navigation and trajectory navigation, and the intelligent robot carries a camera and several sensors.
[0058] This is because, in order to ensure the stable operation of the substation, the inspection of each electrical equipment in the substation can not be sloppy, many times a day inspection, each inspection at least an hour, can not do all-round, especially at night, the operation and maintenance personnel will be tired, drowsiness and other problems, resulting in hidden dangers can not be checked.
[0059] The use of intelligent robots in the present invention can replace manual remote routine inspections, in accidents and special circumstances can achieve special inspection and customized inspection tasks, to achieve remote online monitoring, while reducing labor, greatly improve the content and frequency of operation and maintenance, change the traditional operation and maintenance mode, to achieve intelligent operation and maintenance, intelligent robot through the temperature thermal imager, the use of visual recognition technology, can independently complete the inspection task, large-capacity camera content local storage, seamless synchronous cloud storage, intelligent inspection and analysis. In addition, the intelligent robot can automatically upload the inspection data to the asset system, eliminate the manual export and transmission link, and realize the closed-loop circulation of operation data in the asset management system in an all-round way, automatically import and compare, and as long as it is in the central control system, even if it is thousands of miles away, it can issue instructions to the robot to receive pictures, images, data and other information collected by the robot.
[0060] (4) The data objects collected by the equipment state acquisition subsystem include oil chromatography (temperature of the cooling oil in the transformer), core grounding current (transformer grounding state), lightning arrester (full current size on the lightning arrester, resistive current size and number of actions, etc.), SF6 gas (pressure and density of SF6 gas, and microwater content of SF6 gas) and local discharge.
[0061] (5) The security subsystem is embedded in the central control system, including the access control module and the data intrusion prevention module.
[0062] It is worth noting that the identification unit of the access control module includes but is not limited to password disk, magnetic card, radio frequency card and biometrics, etc., of which the access control module also includes a physical anti-intrusion unit, and the physical anti-intrusion unit collects the arming status of electronic fence, infrared thru-beam, infrared double identification, and has the function of sending information such as anti-zone alarm and fault alarm.
[0063] The use of an integrated information platform for intelligent substations, including the following steps:
[0064] S1, video surveillance subsystem, fire subsystem, environmental monitoring subsystem, inspection subsystem, equipment status acquisition subsystem and security subsystem real-time monitoring of the status of various systems and equipment in the substation, and summarized to the central control system, and then real-time output on the first display and second display.
[0065] S2, in the above S1, the black box subsystem real-time recording of the central control system, video surveillance subsystem, three-dimensional animation model subsystem, fire subsystem, environmental monitoring subsystem, inspection subsystem, equipment status acquisition subsystem and security subsystem of the historical data, but also will record the operation records and call records of the staff in the central control room.
[0066] S3, when a fault is found in the substation, both the first and second displays will display the fault point and fault class.
[0067] S4, the central control system analyzes the fault category and makes an automatic maintenance or manual maintenance command.
