Wind power systems are usually built in harsh environments, and the distance between systems is often up to 1000 meters. In addition, there is power interference between these wind towers, so there is a high requirement for the system's anti-jamming and reliability, so as to ensure the stable operation of the network and the correct transmission of data.
In the field of wind power, the main control system is called the brain of the wind power system. Its stability and reaction speed directly affect the power generation effect. At present, the main control system on the market uses more PROFIBUS communication, such as the master control system of Beckhoff. In this way, for most converter manufacturers, the interference of the PROFIBUS bus in field communication has always troubled users.
The solution adopted by most users for this purpose is to change the PROFIBUS bus cable to optical fiber as the transmission medium. In this way, communication is more stable and reliable, and high-speed long-distance data exchange with slave stations is implemented. At the same time, users face cruel market competition. This solution also has to consider the cost of optical fiber communication hardware for users. With the emergence of a series of new problems such as high and long delivery cycle, Shenzhen News Company proposed Ci-PF110/120 series bus data optical transceivers to propose a full range of cooperation methods for converter manufacturers, and realize the localization of PROFIBUS bus to optical fiber in China. Services and technical support have truly solved a series of problems in the system.
This alternative program has been well-received by users after thousands of years of practical application at the site! For converter manufacturers and control system integration partners to bring a big profit growth point, in today's fierce market competition to obtain more self-control projects to create greater value for the company.
