In February 2022, Innovit Electric was awarded a contract to provide an advanced fault current limiter to the CNOOC “Haiyangshiyou 111” FPSO to solve the problem of abnormally high short-circuit current during the networking of the power system.
FPSO is a key facility for offshore oil development, mainly used for the exploitation, processing, storage, and outbound transportation of offshore oil, natural gas, and other energy sources. The hull was designed and completed by the CSSC in 2001. It was put into production in Panyu Oil & Gas Field on October 1, 2003, and its construction speed has set a world record. It has been in continuous service for nearly 15 years and has produced more than 280 million barrels of crude oil, making great contributions to the development of CNOOC’s oil and gas fields in the South China Sea.
With the continuous increase of industrial and electricity load, power plants and large industrial enterprises often need to install higher power supplies or additional factory generators in the process of production and operation, which leads to the fact that the short-circuit current level will exceed the permissible value of the equipment threatens the security of the power system.
As an ideal switching device to solve the problem of short-circuit current, Innovit Electric’s UFCL-limiter operates and limits the short-circuit current in the early stage of the first rise and realizes the interruption before the short-circuit current reaches its peak, so that the total fault current level is within the withstand and interrupting capacity of the switch. Compared with the complicated conventional solutions, the device has the advantages of reasonable technology and economic advantages, whether it is applied in the transformer or generator feeder, in the bus tie of the switchgear, or in the connection in parallel with the reactor.
