| The Chengdao Oil-field of ocean oil extraction factory is located in the neritic and the most neritic waters of gulf the south of Bohai Sea, the water in the seas deep 10 meterses are or so, it has already developed to become a year to produce 2,000,000 ton class oil-field.Because the environment of sea is very bad, the oil extraction platform all guards a design for unmanned value, the production and life the condition is very hard, the oil-field successfully carried out a craft automation and carried out platform no man value the problem guard, but immediately bringing is to can not go together with and give or get an electric shock a system circumstance and carry on supervision to the platform, at the sea go together with and give or get an electric shock system and expose shortage gradually, particularly the strong wind sky could not resume power supply in time while appearing and the power is off trouble and brought sea production very greatly difficulty and loss.For the sake of safety production and raising an oil extraction rate,we have to carry out the electric power automation technique to realize the automation management of giving or getting an electric shock the system.With the study to the electric power automation, contrasting each kind of system, we optimization suitable system of offshore platform, particularly choose a type to carry on an optimization to the equipments which ensure satisfy sea request. The system constitution is at centrally No.2 platform, including the No.2 35 KV in center substation, the 6 KV high pressure switch cabinet and four well sets platform high pressure facilities,. The system adopt industry control network, goodly open sex and and permit sex, ability solid monitor charged barbed wire net parameter, carried out the remote control, telemetering, information,adjust etc. function.With the estigating about automation, combining the spot physically, we carried on an extensively thorough research to the system, particularly to the structure of the system, lord station system, son station system, carried on after electricity protection, communication system, electricity equipments, soft hardware and system test acceptance etc. detailed thorough of research, we excellent each function design for turning system, carried out the safety of system to efficiently throw in movement. With the research,we carried out the innovation of many systems:Various techniques merge into an integral whole and made use of electric power SCADA and turn system after the soft hardware integral whole of electricity techniques, such as protection, wireless communication, network communication and optoelectronics communication...etc.;Adopted several RTUs of factory house and conduct electricity Taiwan, optoelectronics after the electric appliances, intelligence gauge, number conversion products, such as machine and satellite clock...etc., collect a data to have great capacity, the function is strong, and permits sex strong;The data collected when carrying out was solid, telemetering, the remote information, control,adjusted, data statement etc. function;Circulating environment is bad, but the credibility is strong;The system at often year's on the water movement in difference in temperature more big, the degree of humidity is big, the environment is bad, because this machine backup, operation record, break down record wave, solid reported to the police an etc. technique to raise the credibility of system.The implementation of the research has good economic efficiency and social efficiency,it raised a sea transformer substation of safety, dependable, it carry out sea electric power automation of efficiently circulate. |
