Distribution system automation master mode

Distribution system automation master mode The integrated master station mode of the distribution management system refers to the use of a master station system to monitor and manage all the distribution networks in the areas under his jurisdiction. The system communication predecessor communicates with all substation systems within the jurisdiction, remote terminal unit (RTU), feeder remote terminal (FTU), transformer test terminal (TTU), etc., using a unified database, including SCADA at the master station level. Distribution management systems, including systems and feeder automation systems, manage distribution networks.

Adopting the integrated master station design scheme requires the construction of a large-scale master station system that includes the functions of geographic information systems. The functions are perfect and resources and information can be fully shared to prevent overlapping of equipment and functions. At the same time, duplicate investments can be avoided. The disadvantages are the complexity of the system, the large investment, and the long construction period. Because the functions are too concentrated, the reliability of the system is required to be high, so the impact of system failure is large.

The integrated master station scheme is a vast system project that is applicable to power supply units with a relatively developed economy and abundant capital. In China, distribution automation is still in its infancy, and there is no long-term operation experience. There are many contents that do not have standards and specifications, and it is not advisable to establish a large-scale distribution network management system with complete functions. From the point of view of realizing the function of distribution automation, that is, substation automation and feeder automation, in order to save investment and enhance system flexibility, a large integrated master station system is not required, and a two-stage master station mode may be used.

Water Treatment

Water treatment chemicals are agents that can react with other impurities in the water when put into the water. Mainly for the purpose of purifying water. Common water treatment agents are poly aluminum chloride, polyaluminum ferric chloride, basic aluminium chloride, Polyacrylamide, ferrous sulfate, aluminium sulfate, polyferric sulfate etc.

Water treatment agents produced by Jinhe Industrial are green products.They own good water purification effect, fast water purification speed, weakly acidic pH, inorganic, high safety, no secondary pollution.It has strong purification effect and can remove heavy metals in water. The treated raw water is not affected by water temperature and pH, and has a wide range of use. The treated water has extremely high transparency and can be reused.

The most used water treatment chemicals are Flocculants. Flocculants include two categories: inorganic flocculants and organic flocculants. Organic flocculants are classified as ionic and non-ionic.Poly Aluminium Chloride and Aluminium Sulphate produced by Jinhe Industry are inorganic flocculants.And our Polyacrylamide belongs to organic Flocculants.

Poly aluminum chloride,aluminium sulfate and polyacrylamide produced by Jinhe Industrial are widely used in both industrial waste water treatment and drink water treatment. The water treatment effect are perfect.
