摘要
[目的]为了提高舰船电力系统的安全性与稳定性,提出基于比例伪时序算法的风险评估系统。[方法]在舰船电力系统中引入改进的伪时序算法,对电压、功率和频率等电力模拟量进行赋值,并通过组态界面进行可视化监控,进而对舰船电力系统进行整体风险评估。同时,针对不同工况下的系统拓扑结构变化问题,通过引入比例补偿系数来调整算法,从而提高风险等级评估的精确度。[结果]实机测试结果表明,该系统不仅可以实时监控电力物理量,还可以准确评估系统的风险状态和风险水平。[结论]研究成果可为舰船电力风险评估系统设计提供参考。
[Objectives]In order to improve the safety and stability of a ship’s power system,a risk assessment system based on a proportional pseudo time-series algorithm is proposed.[Methods]An improved pseudo time-series algorithm is introduced into the ship’s power system to assign values to power analog quantities such as voltage,power and frequency,which can be visually monitored through the configuration interface;the risk assessment of the overall power system is then conducted.At the same time,in response to changes in system topology under different working conditions,the algorithm is adjusted by introducing proportional compensation coefficients to improve the accuracy of risk level assessment.[Results]The actual test results show that this system can not only monitor the physical quantities of electric power in real time,but also accurately assess the risk status and level of the system.[Conclusions]The results of this study can provide references for the design of ship electric power risk assessment systems.
