With the development of the times, the application of networks in China is becoming more and more common. At the same time, with the development of the power sector, more and more networked technologies have been applied in the development of enterprises, especially in recent years. With the continuous development of China's overall economy, the power sector has also developed rapidly, and at the same time, it has also driven The rapid development of power network communication technology. So far, power network communication services have covered two-thirds of the country's urban areas, and there is a tendency to gradually expand. Therefore, how to achieve the standardization level of power network technology requirements, how to ensure the quality and safety of power network communication services has become the most important link in the development of the current power sector, but also a crucial link.
First, what is power network communicationThe so-called power network communication mainly refers to the business control functions that are related to power production and are highly related, as well as the administrative business scope associated with power production. In the power network communication technology, there are different network parameter control standards for different power production services. The power network communication system is composed of three main parts: power supply, internal basic equipment and monitoring terminal. In the operation of the power network communication system, the power supply is the basis for supporting its normal operation, so the technical requirements for the safety, stability, durability, and efficiency of the power supply are high. Because only the power supply is continuously supplied, the normal operation and safety of the power network signal system can be ensured.
Although the power network communication system has been relatively perfect with the development of the times, there are still some restrictive problems in the actual operation. This is mainly reflected in the following points:
1) Power network communication system has poor reliability
At present, although the development speed of power network communication system is relatively fast, in practice, the problem of poor security and reliability of power network communication system is common. At the same time, when power network communication is running, the ability to share data information resources still exists. More deficiencies. If the communication failure occurs in the central system or at a certain site during the operation of the power network communication system, the overall power network communication system is in a paralyzed state. In addition, many power network communication systems are also very common in the long-term operation, the phenomenon that the power network communication equipment caused by the staff's care and maintenance is not in place is accelerating into the aging period. As a result, the overall safety and stability of the power network communication system can be reduced, affecting the normal development of the power sector.
2) Power network communication transmission quality is poor
In the current power network communication system, the network cable generally does not have a better shielding layer as a support in the transmission, so that the interference problem in the network communication transmission cannot be solved. In addition, the network used in the power network communication system is mostly a single-strand copper wire, and the copper wire is relatively easy to be broken during the operation of the device, so that the network defect caused by the wire breakage in the power network communication process is prone to occur. In addition, since the copper wire has a thin wire diameter and a light weight, it cannot be connected to other devices during operation of the network communication system, resulting in singularity of data transmission. In addition, the requirements for power consumption in different regions are also different. Therefore, the sDH node is relatively complicated. At present, many connection nodes in many SDH networks have caused the power network communication system's own anti-failure capability to be greatly reduced, which seriously affects the quality and security of data transmission by power network communication.
3) Power network communication structure is complex
At present, the domestic power network communication management structure is generally divided into three levels of network communication level: first level, second level and third level. At the same time, the operation structure of the power line is relatively complicated. In addition, with the development of various economic constructions in the country, the small and medium-sized substations are also increasing, and the sDH nodes used in each substation are continuously connected in series to the original sDH network of the power network communication system. The sDH network is formed into a more complex node connection mode. In addition, with the development of the times, many power network communication systems also need to transmit data simultaneously across the ring network or even across multiple ring networks, thus causing the system failure of the power network communication system to meet the data transmission requirements.
Third, power network communication fault prevention measuresEffective power network communication fault prevention measures are the basis for ensuring the normal operation of network communication in the power sector, and also an indispensable link to improve network communication capabilities. Therefore, the power department staff has undergone continuous research and analysis, and summed up a set of targeted power network communication fault prevention measures, the specific contents are as follows:
1) Establish a sound power network communication system
First of all, the power sector should standardize the structure of the power network communication system according to the power consumption of different regions. At the same time, the power network communication operation in the region is monitored and evaluated at any time, and the implementation effect of the power network communication is standardized. In addition, the power department must formulate a series of standardized and reasonable power network communication system maintenance and management system systems, and The power network communication maintenance and management tasks are detailed and distributed to every staff member in the power sector. At the same time, reasonable design and technical index requirements are made for the operational reliability and security of the power network communication system, and the network communication technology is re-planned based on the safety and reliability of the power network communication system. At the same time, under the premise of limited construction conditions of the power network communication system, the actual analysis and identification of the network communication operating state is carried out. At the same time, it studies various faults in network communication operation, and formulates specific preventive measures for the causes of faults.
2) Establish a power network communication navigation system
It is very important to establish a network communication navigation system to effectively prevent power network communication failures. First of all, the power sector should provide a new power network communication navigation system, technical consulting system and operational procedures of each system. At the same time, the power sector should store a large number of network communication equipment as well as network performance and parameter technical data. In addition, intelligent high-tech service devices are added to the power network communication system. In this way, the power network communication staff can be assisted to find the point where the network communication is faulty, and the maintenance speed of the fault is improved. In addition, the navigation system service technology can also assist the staff to find and solve different fault problems in the operation of the power network communication system. Not only can the operation function of the power network communication system be greatly improved, but also the work intensity of the staff can be effectively reduced, and the development of the power network communication technology can be accelerated.
Fourth, summaryIn summary, solving the power network communication failure is the basis for ensuring the normal operation of the power sector. Therefore, it is necessary to formulate specific solutions and preventive measures according to the specific points of the power network communication failure, and improve the operational capability of the power network communication system.
