Abstract
Offshore drilling platform is the exploitation and production base on the sea. Platform power system is a stand-alone power generation,transmission and distribution system. It is very significant for offshore drilling platform to be equipped with real-time and reliable power monitoring system.
This paper takes the sixth generation semi-submersible drilling platform as object of study.According to the request of power generation,transmission, distribution,electricity, other equipment load configuration and automatic monitoring system,a platform power monitoring system is developed by using the technology of network,database,software and others.It has practical value. The concrete researchs are as follows:
According to the feature of the communication interface of offshore power system equipment,fieldbus is selected as the network structure of field devices.And According to the overall requirements of platform power monitoring system,industrial Ethernet is selected as the network structure of workstation and server.And the network construction work of semi-submersible offshore platform power monitoring system is completed.
According to the side of design principles,requirements,functions and data structure of offshore platform integrated monitoring database,historical database and real-time database is designed.
Power monitoring interface of semi-submersible is designed by using IFIX configuration software.Including monitoring interface of diesel generator set,propulsion and power management,etc.
Method of calculating platform power plant capacity and work mode optimization of main transformer of power system are studied.Pre-diagnostic function of power mode conversion is designed and implemented based on multi-agent model.And the feasibility of pre-diagnostic strategy based on multi-agent model is verified by example.The diagnosis can provide information for decision making of the selection of power mode conversion path.
Power monitoring system is implemented by using VB and IFIX configuration software.Including the real-time display of diesel generator parameters,operational status,fault information and the function of reload asking,light-load splitting,multiple generators automatical starting,etc.And its monitoring function is tested by simulation data,and the test results show the effectiveness of the monitoring function.
Key words power monitoring; power supply mode; Semi-submersible platform; IFIX
