舰船阴极保护系统电流控制研究

Research on Current Control of Ship Cathodic Protection System

针对舰船船体防腐与电场隐身相矛盾的问题,采用了集成式外加电流阴极保护系统代替传统分区式外加电流阴极保护系统,提出了建立在水下电场和参比电位测量信息基础上的电流调整策略和计算方法,并将相对于自然腐蚀状态的阴极保护电流的优化问题,转化为相对于电场隐身时水下电场增量的最小化问题。仿真算例证实了所提电流控制策略的有效性。

In view of the contradiction between ship hull anti-corrosion and electric field stealth,an integrated impressed current cathodic protection system is adopted to replace the traditional zoning impressed current cathodic protection system,and a current adjustment strategy and calculation method based on the measurement information of underwater electric field and reference potential are proposed.It is transformed into the minimization of underwater electric field increment relative to electric field stealth.Simulation examples show the effectiveness of the proposed current control strategy.
