It should be noted that the present application also provides an alternative implementation, and the details of the implementation are described below.
Line relay protection devices are arranged at two ends of an alternating-current and direct-current extra-high voltage line and a high-voltage transmission line of a power grid, the line relay protection devices need real-time and reliable mutual communication, a 2M service channel in SDH (synchronous digital hierarchy) optical transmission equipment is used as a common communication channel at present, and fig. 3 is a schematic diagram of a line electromechanical protection system according to an embodiment of the invention and is specifically shown in fig. 3. Once the relay protection devices at the two ends of the line detect the line fault, a switch cut-off instruction is sent in the shortest time, the protected line is isolated from the power grid, the power transmission line is protected to the greatest extent, and the expansion of the accident loss is avoided.
The communication modes of the optical fiber protection device of the AC line currently use 4 types: the optical fiber direct connection mode, the 2M multiplexing mode, the 2M switching equipment mode and the 2M optical port mode.
Fig. 5 is a schematic diagram of another line protection communication connection according to an embodiment of the present invention, as shown in fig. 5, a power grid communication service serves an electric power production service, the power grid has a large number of single-channel 2M multiplexing protection devices operating on the power grid, and for the reliability of the power grid operation, it is necessary to ensure high reliability of the communication service, so that the power communication network has a plurality of sets of SDH transmission networks. The 2M switching equipment intelligently selects one set of the two sets of SDH transmission networks as a transmission route of the 2M service. The 2M switching equipment is typically applied to relay protection communication services.
In fig. 5, normally, 2Ma is used as the main channel, but when a set of SDH fails, 2Ma generates a corresponding alarm, the 2M switching device automatically switches the service channel to 2Mb, and the relay protection communication service continues to operate normally using a set of SDH transmission systems B. Therefore, the reliability of the communication service of the relay protection device is guaranteed, and the operation safety of the power grid is improved.
In the mode 3, the photoelectric conversion box and the 2M switching device are two different devices belonging to different management departments of the power grid for management, and in the modes 2 and 3, the photoelectric conversion box becomes a fault point, so that the network management cannot be centralized, the maintenance is inconvenient, and the operation safety of the power grid is influenced.
The method 4 is suitable for newly-built lines, the new relay protection devices are AB ports and have double routes, and SDH equipment has standard 2M optical interfaces. For old sites, neither the relay protection device nor the SDH equipment has a standard 2M optical interface, and the method 4 cannot be implemented.
Compared with the 4 communication modes of the relay protection device, the mode 3 is better for the existing single-channel relay protection device with a large number of channels, and the reliability of the power grid is greatly improved. However, the photoelectric conversion box in the mode 3 is only powered by a single power supply, and cannot remotely centralize network management, which is a common fault point.
The implementation mode cooperates with a 2M switching equipment manufacturer, the manufacturer carries out technical development, and an optical interface is added to the 2M switching equipment to be directly connected with the relay protection device. Fig. 7 is a schematic diagram of another line protection communication connection according to an embodiment of the present invention, and as shown in fig. 7, two devices, namely, a 2M switching device and a photoelectric conversion box, in a communication room are actually combined into one, so that the photoelectric conversion box is reduced, the problem of channel 1+1 route switching is solved, and a network manager can be remotely centralized. The method has great significance for safe and stable operation of the relay protection device.
In the embodiment, only the optical interface module is required to be added on the 2M switching device, the hardware cost is slightly increased, but a set of MUX2M equipment is omitted, and the 2M switching device is still a 1U19 inch case after the optical interface is added on the 2M switching device, so that centralized and unified network management can be realized, and the operation and maintenance are convenient. As long as the communication department is coordinated and matched with the protection department, the method is easy to popularize and apply in each provincial network of the national power grid.
With the increasing number of relay protection services carried by a single optical fiber, 2M switching devices have gradually gained high attention from the national grid communication management department in recent years, and for a large number of currently-operated single-channel relay protection devices, the addition of 2M switching devices is the best solution.
The optical port is arranged in the 2M switching device, so that the MUX2M device is removed, and no unit research application exists at present.
The problem of high failure rate and maintenance blind spot of active equipment in a communication section from protection equipment to switching equipment in a mode 3 is solved by newly developing a switching equipment with an optical interface, which is hereinafter referred to as a new switching equipment for short, the device is provided with one path of optical interface and two paths of electrical interfaces, services transmitted by the three paths of interfaces are 2M data communication services of a relay protection device, wherein the two paths of electrical interfaces are respectively connected with two 2M transmission channels with independent routes in a transmission network, one path of optical interface is directly connected with the optical interface of a relay protection device, and the device is provided with a transmission side 2-path communication link switching function, namely, one path of optical interface can be selected from two paths of transmission links to transmit the relay protection 2M data communication services of the optical interface, the transmission performance of a service transmission link can be monitored in real time, and once a failure or performance deterioration is found, the link switching is immediately carried out according to a preset, therefore, the influence on relay protection communication service is reduced to the minimum.
The new switching equipment transforms the 2M electrical interface used for connecting the relay protection device in the original device into an optical interface on the basis of the original switching equipment, and the optical interface is directly connected with the relay protection device in an optical medium communication mode, so that a middle photoelectric conversion device is omitted, a fault point is reduced, and the problems of high fault rate and maintenance blind point of the communication section are solved by means of high reliability and high maintainability of the switching equipment.
In order to adapt to the current application situation of a relay protection device, an optical interface of new switching equipment needs to be compatible with the current domestic mainstream relay protection device, physical and link layer rules such as a line coding mode, a timing synchronization mode, a level judgment rule, a channel error correction coding mode and the like of a communication interface of the mainstream relay protection device are researched, an optical communication interface module corresponding to the optical communication interface module is developed, and the optical interface module is butted with the relay protection device on the premise of not changing the original relay protection device to complete the photoelectric conversion function of the original photoelectric conversion device, so that relay protection communication services can be conveniently and smoothly transferred to the new switching equipment.
The optical communication is widely applied due to the characteristics of high communication speed, strong anti-interference capability, long transmission distance, low cost and high reliability, and is a poor choice especially in high electromagnetic pollution environments.
The code stream to be transmitted in the digital communication system is generally an NRZ code, and in order to adapt to the transmission characteristics of the communication medium, the NRZ code needs to be converted into a digital code stream suitable for channel transmission, which is a process of line coding.
In digital optical communication, the principle of simple and low cost is generally adopted for baseband digital transmission, and meanwhile, the optical fiber transmission characteristic and the receiving and judging regeneration characteristics of an optical receiving device are considered, so that optical communication line coding must meet the requirements of limiting signal bandwidth, reducing high and low frequency components of power spectral density, providing rich timing synchronization information and providing auxiliary communication bandwidth.
There are many types of optical communication line codes, and two types of optical communication line codes are the most common, one is a block code mBnB, and the other is an inserted bit code mB 1X.
The grouping conversion code mBnB groups the communication payload content into a group according to m bits, and then maps each group into a binary code group of n (more than m) bits according to a certain rule. The mapping rule follows that the occurrence probability of the code elements of 0 and 1 in the transformed code group is equal; the number of the connection '0' and the connection '1' is reduced, the number of the connection '0' and the connection '1' cannot exceed m-1 bits, timing information is rich, and timing and regeneration of a clock are facilitated; the power spectral density has less high and low frequency components and small baseline drift; and a certain redundancy is introduced into the code stream, so that error code detection and auxiliary communication are facilitated.
Inserting a bit code mB1X, grouping the communication payload code streams into a group according to m bits, and then inserting a code word X into the back of each group according to a certain rule to form a line code stream with m +1 bits as a group.
As can be seen from the conversion method of line coding, both the packet conversion code mB nb and the inserted bit code mB1X trade off the communication performance for the communication bandwidth increase and the communication efficiency sacrifice, which are almost negligible in the low-speed optical communication system.
