Simulation Analysis of a Subsea Hydraulic Control System Based on SimulationX

水下控制系统是水下生产系统的重要组成部分,电液复合式控制系统是目前最常用的水下控制系统,其参数的设置对水下生产系统的安全具有重要影响。本文采用SimulationX对低压液压系统进行仿真分析,研究了水深、回接距离、液压管线直径、水下蓄能器参数以及液压动力单元液压泵参数对充泄压时间以及采油树闸阀开关时间的影响规律。研究表明:在本文模拟工况条件下,脐带缆液压管线直径和回接距离是2个对系统充泄压时间影响较大的参数;采油树闸阀开关时间受本文考察因素影响较小。本文可为今后水下控制系统液压分析提供一定的参考。

The subsea control systenant partof the subsea produetion system.The electro-hydraulic contrlsystem is the most commonly used subsea control syetem,whoseparametter setting has an important im pact on thsafetyof the subsea production system.In this paper,SimulationX is used to simulate the low-pressure hydraulisystem.The effects of water depth,tieback distance,hydraulic pipeline diameter,subsea accumulatorparametersand HPU pump parameters on the charging and ESD(electrostatic discharge) time,and the open and close timeoftree gate valve are analyzed.The results show that under the simulated working conditions;the diameter of theumhilical hydraulie pipeline and the tieback distanee aretwo parameters which hava great infiuenceon the systerin this paper.This paper provides some reference for the hydraulic analysis of subsea control system in the future.
