Description
Technical Field
The invention relates to the technical field of intelligent transmission of distribution network fault information, in particular to a 5G-based intelligent transmission system of distribution network fault information.
Background
In an urban power grid, for a load-intensive area, power is mostly supplied to users by building a switch station. With the large-scale transformation and development of power transmission, distribution and transformation networks, the number of switch stations in various regions is synchronously increased, and the switch stations are used as the Shanghai of the most developed long triangular faucet city in China. However, the practical situation of the current engineering is that the power grid monitoring system mainly monitors and controls the power grid equipment of more than 110kV in a real-time centralized manner, and an effective monitoring technical means is lacked for branch lines and equipment of 10kV and below, especially for protection equipment in a 10kV switching station.
The equipment configuration of the station control layer mainly comprises the following parts:
(1) station level operator station (i.e. background machine): such as MMI, TELEGYR and VATECH-SAT of ALSTOM, and SIEMENS.
(2) Station level master control unit: such as CCA from ALSTOM, front-end computer from TELEGYR, SK1703 from VA TECH-SAT, and 6MB551 from SIEMENS.
(3) Telecontrol communication interface: for example, ALSTOM and TELE-GYR are dedicated devices (TE and Router), VATECH-SAT and SIEMENS are configured with corresponding interfaces on their station level master control units (SK1703 and 6MB 551).
(4) The optical fiber network equipment comprises: are all optical fiber nets. In terms of network structure, the British Edbye transformer substation adopts a layer of network, namely an Ethernet is directly arranged on a spacer layer, and the rest of the network is two layers of networks, namely a station level network and a spacer level network.
(5) The clock synchronization system comprises: the united kingdom uses the GPS time-pair standard and the other three stations use the DCF77 radio time standard (german domestic).
(6) A data document processing computer: according to specific conditions, some personal computers are configured with special documents and data processing computers, and store and record events, data and various reports.
Although these monitoring systems come from different manufacturers, the system structure mode and the implemented functions are largely the same. All the devices of the station control layer can be configured redundantly according to needs, and the station level network and the interval level network can be configured redundantly. In the aspect of station-level system network, the ALSTOM and TELEGYR adopt IEEE802.3 standard Ethernet, the VATECH-SAT adopts SATNET network, and the SIEMENS adopts interactive Ethernet. The spacer layer network mostly adopts a star-shaped optical fiber network.
For the station level main control unit, all companies provide special developed special equipment with powerful functions, and the station level main control unit is characterized in that:
(1) hardware working platform of station control layer
Hardware is divided into two categories: one type is a background computer of a station control layer, which comprises a station-level operator station and a data document processing computer; the other is a station level master control unit. For the operator station, there are systems using a workstation (DEC) and systems using a microcomputer (PC). As for the station level master control units, dedicated devices of a multi-processor structure are adopted as described above.
(2) Software working platform of station control layer
Foreign users do not pay much attention to which operating system is adopted by the automatic system. From the practical application, the method mainly comprises UNIX and WINDOWSNT. The method has a certain consensus on the stable UNIX operating system, difficult virus infection, more bug of the WINDOWS system and easy virus infection, but has no problem if the software of the monitoring system is mature and well managed. The manufacturers can provide transformer substation monitoring system software of the two operating system platforms. Such as SAT250(UINX), SAT230(windows nt) and SAT200(DOS) by SAT corporation. SPACE2000 by AL-STOM also has both UNIX and WINDOWS versions, with SIEMENS' LSA substation automation system employing WINDOWS snt.
(3) For the communication between the automation system and the equipment at the bay level and to the outside, each company shows the use of IEC and related european standards. And gives full attention to IEC 61850.
Remote and local control operations of an automated system are implemented in substantially the same manner as most systems in the country. The automation system can receive control operation commands of a remote place (a dispatching or control center) and a station-level operator station, and can also directly send the commands to a station-level main control unit or a bay-level device through a portable computer or an operation panel. Normally, all control is operated by a remote dispatch center. Other modes are used during debugging and overhauling. The operation anti-misoperation locking function of the total station is completed by the station level main control unit, and the interval layer device only realizes the operation anti-misoperation locking function of the interval. If a command is issued on the wall device, the information relating to the locking condition of the total station is fetched by the wall device from the station level master control unit.
And for the remote control command, the remote control command is firstly sent to the station-level main control unit and then sent to the bay level device by the station-level main control unit to be executed. In a system using the bay level direct access scheme (e.g., SPACE 2000V 2.10 version of ALSTOM corporation), the remote control command is also first sent to the station level computer (i.e., the station level master control unit) and then sent to the bay level device by the station level computer for execution. It can be seen that the information flow direction of the remote control commands of each monitoring system is the same, namely, the control center → the station level main control unit (station level computer) → the bay level unit.
The automation system of the foreign unattended substation has the following common characteristics in equipment configuration, system structure and function distribution of a station control layer:
(1) due to the unattended transformer substation, the configuration of the background computer is relatively simple. Station level operator stations are used primarily for system commissioning, field maintenance, and substation extension, depending upon design considerations. The functions of the background machine are simplified, and many functions are assigned to the upper-level control center. The reliability of the system depends on the reliability of the station level main control unit (station level computer) and the bay level measurement and control device and the network communication between the station level main control unit and the bay level measurement and control device.
(2) The station level master control unit actually functions as a master computer of the substation automation system, and thus the requirements on the station level master control unit in terms of functions, processing capability, communication capability, processing speed, and reliability are high. The station level main control unit is a special function device with a multi-32-bit CPU structure and ultra-strong communication capability, and redundancy configuration is adopted to increase the reliability and the availability of the whole automation system.
(3) In the aspect of anti-misoperation locking of control operation, the station level main control unit is responsible for the anti-misoperation locking function of the whole station, and the interlayer device is only responsible for the anti-misoperation locking of the interlayer.
(4) As a link of the whole automation system, the network is formed by optical fibers so as to improve the interference rejection level of network communication. Both the station level network and the interval level network support a dual-network redundancy structure.
At present, the common modes of the switch station monitoring in China comprise a centralized DTU (data transfer unit), a distributed DTU (data transfer unit) and a distributed protection and measurement integrated device.
(1) Centralized DTU: the most common mode is that monitoring of the switching station is realized through an RTU (remote terminal Unit), and 10kV feeder line data acquisition and control of the switching station are completed as the RTU is scheduled automatically;
(2) distributed DTU: the terminal DTU equipment is installed in a distributed manner in the switch cabinet;
(3) distributed guarantee and measurement integrated device: adopt protection observing and controling integrated device, the dispersion is installed in the cubical switchboard.
The above modes are all only used for monitoring the running state of the primary switch equipment, and the running information of the secondary equipment such as a protection device in a switch station cannot be monitored in real time and rapidly acquired; the operation information mainly comprises protection device parameter information such as version and check code, ledger information such as unique identification code, protection constant value and soft pressing plate information, protection analog quantity and state quantity information, protection device fault recording information and the like.
The substation is generally provided with a protection fault information system substation, which can collect the operation information of the protection device and the recording information of the fault recorder, and the information is transmitted to the main station after being processed by the substation. However, a conventional substation usually adopts a 103 protocol, the protection device transmits information to the information protection substation through a serial port 103 or a network 103 protocol, and the information protection substation transmits the information to the main station through the 103 protocol. In the intelligent substation, the similar information of the protection device is collected by the information protection substation in an IEC61850 communication mode, is generally transmitted to the information protection main station by adopting protocols such as national network 103(GDW273) and the like, and is also transmitted by a part of unit test points in a file mode by using a general service protocol. However, in actual operation, no matter a new station is put into operation, a new interval is put into operation, or primary and secondary equipment change needs operation and maintenance personnel to coordinate debugging at the main station and the sub station, and operation and maintenance are complex. Because 10kV switchyard is big in quantity, and the position in a storehouse cuts and connects many, the letter protection sub-station of transformer substation constructs and moves to 10kV switchyard with the fortune dimension mode, and the fortune dimension work load of switchyard and main website will greatly exceed field personnel's bearing capacity, can't realize the practicality.
At present, the 10kV switch station has dispersed positions, large deployment amount of protection equipment, complex installation, debugging and configuration, diversified communication forms, difficult operation and maintenance and serious dependence on manufacturer personnel on reconstruction and expansion work, at present, effective real-time monitoring on operation information of secondary equipment such as a protection device in the switch station is generally lacked, and the operation and maintenance personnel can only regularly patrol.
