基于电力推进的动力定位海洋平台位移储能控制策略
Displacement Energy Storage Control Strategy for Dynamic Positioning Offshore-platform Based on Electric Propulsion
摘要
Abstract
In order to solve the problem of power fluctuation caused by the change of operating load conditions and sea conditions in offshore-platform power systems,this paper proposes a displacement energy storage control strategy of dynamic positioning(DP)offshore platform based on electric propulsion.By establishing the dynamic positioning system of the offshore platform and the three-degree-of-freedom kinematics model,the quantitative relationship between the offshore platform displacement deviation and the displacement energy storage power is obtained.A control method utilizing displacement energy storage to respond to power fluctuations in the electrical propulsion system is introduced.With the aim of addressing the issue of significant delay in response of displacement energy storage control,a direct relationship between system frequency,dynamic positioning displacement energy storage and electric propulsion compensatory torque is established.This enables the participation of displacement energy storage in dynamic frequency regulation,thereby enhancing the stability of the power system frequency.Finally,the model of dynamic positioning offshore platform power system is established by RT-LAB semi-physical platform to verify the power fluctuation mitigation effect of the proposed control method in this paper.关键词
