Design and Optimization of Lifting Control System for Jack-up Drilling Platform
This paper probes into the design method of lifting control system of jack-up drilling platform,and optimizes the horizontal control of drilling platform and synchronous control of pile leg motor.The system is composed of three modules:power transmission,lifting control and sensor.DCS distributed structure is adopted.The central industrial computer is used as the upper computer and the PLC control box is used as the lower computer.After the front-end sensor collects the load,speed,levelness and other signals,it uploads to the industrial computer and completes the analysis and processing,and then generates the corresponding control instructions and sends them to the next computer.The motor on the pile leg is controlled by the lower machine to complete the lifting operation,which ensures the level and stability of the drilling platform.The level instrument is arranged on the drilling platform,the displacement deviation in the horizontal direction is transformed into the velocity deviation,and the pile leg is regulated independently to achieve the purpose of level control optimization.The coupling control mode is applied to the pile motor to ensure that the motor runs in a balanced and synchronous manner,and the purpose of synchronous control optimization is achieved.
