Design of Control System for Hydraulic Lifting Platform with Jack-Up Wind-Power Installation Vessel

Abstract

Jack-up wind-power installation vessel is the most important tool in construction of wind farm. And the control system for hydraulic lifting platform is the key point of jack-up wind-power installation vessel. Therefore the design of the control system for hydraulic lifting platform with jack-up wind-power installation vessel is a basic and formidable problem. This article provides an integrated solution to the design of control system. Firstly, on the base of actual working condition, we introduce the control principle and basic requirements of the hydraulic lifting platform, such as the structure of leg, vessel gradient, alarm, calibration. Secondly we introduce the design solution of PLC (Programmable Logic Controller) control system, which includes the design solution of hardware as well as software for the hydraulic control system. In this part, we introduce the basic components and main function of hydraulic control system, hardware scheme, software design project. Then we introduce a good human-machine interface. Finally we do the work of program design according to the process of lifting unit. By using wincc-flexible and PLCSIM, we can layout the control module well and realize the man-machine interaction. At last, we can obtain a viable hydraulic control system and verify feasibility of the hydraulic control system by simulation software. At the same time, we obtain the working parameters of the lifting unit from the simulation.
