Design Of The Locking Device Control System For A Jack-up Drilling Platform Based On Step7

With the development of science and technology,the shortage of energy has become the main reason for the restriction of development.The oil and gas resources in the interior have been unable to meet the demands of people,and the development of Marine resources has become the focus.In the Marine oil gathering operation,the most important is the drilling equipment.This paper introduces the offshore drilling equipment in detail,and introduces the drilling equipment of different water depth operation.This paper introduces the drilling equipment is widely used in breeding ground for drilling platform,as a widely used drilling equipment device is the core of leg of the lifting system and use with locking device.The general principle and function of the self-elevating drilling platform locking system are explained.To ensure a stable work platform and face all kinds of special sea condition,the locking system on jack-up drilling platform is particularly important in order to ensure rapid locking safety lock system of platform is needed to monitor the state of lock in work to ensure the synchronization of two groups of motor and load balancing.Frequency control of motor speed has become the mainstream of ac motor speed regulation,frequency converter is widely used as the driver of the motor,it can not only control the turning speed of the motor,at the same time to monitor the running state of the motor.In this paper,a kind of cross-coupling control is studied to realize the precise control of frequency converter and PLC.The purpose of this system is to change the risk of hydraulic locking system and reduce the problems that may be encountered during operation,thus achieving the free manpower and improving the efficiency of work.The system can obtain and process the real-time information of the motor in real time,thus realizing the automation and reliability of the locking system.
