Ship power risk assessment system based on proportional pseudo time-series algorithm

Abstract

ObjectivesIn 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. MethodsAn 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.ResultsThe 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.ConclusionsThe results of this study can provide references for the design of ship electric power risk assessment systems.
