It is understood that Jeju Island is an island of South Korea, and most of the power of PP835A comes from South Korea. The two HVDC converter stations that ABB helped to build this time will provide 200 megawatts of additional power for Jeju Island, which can meet the power demand of 500000 households. In addition, the PP835A voltage source converter (VSC) technology will also provide additional power stability and reduce the risk of power failure to a minimum, so as to ensure that Korea Electric Power Company can operate the existing interconnection network on the island more effectively.
Fang Qin, president of ABB Group’s power grid business unit, said: “ABB is committed to helping South Korea achieve the goal of significantly reducing carbon emissions by 2030. PP835A Our cooperation with Korea Electric Power Company is another important milestone in achieving this goal. ABB’s high-voltage DC system will create a stronger and PP835A greener power grid for local residents, and benefit tens of millions of tourists who visit Jeju Island every year.”
It is reported that ABB will apply light HVDC transmission system based on voltage source converter technology to two converter stations. High-voltage DC transmission is the most effective way to transmit large-scale power over a long distance, and PP835A is the most economical and environmentally friendly way, with power loss of only about 1%. PP835A and above are relevant information about ABB Power Grid Business Department’s cooperation with South Korea to help South Korea build a clean energy future.

2.3 Characteristics and functions of pIc
(Main features of PLC. The features of PLC are reliable operation, fast operation, building block structure, flexible combination, good compatibility, simple programming and generation, rich functions and strong network functions.
(Main functions of plc. PLC system can well complete industrial real-time sequence control, condition control, count control, step control and other functions; it can complete analog/digital (a/d), digital/analog
(d/a) conversion, data processing, communication networking, real-time monitoring and other functions. Years of practice has shown that the plc has reliable performance, is specially designed for the factory, and has reinforced components according to the requirements of the working environment,
Real-time scanning practice and fault diagnosis function, convenient troubleshooting, deeply favored by users. What makes pIc so reliable is for executable relay logic, sequence function diagram, function block, structure text
Command directory or its combination of real-time core or operating system. In case of failure, the built-in equipment can maintain mechanical damage in an orderly and predictable sequence.
2.4 Development trend of PLC: it has extremely fast logic operation and logic control, sequence control ability, and has certain reliability in discrete control. The programming method is easy to learn
Has an undisputed position in the field of industrial automation.
