Abstract

The invention belongs to the power system risk evaluation technical field and provides a risk predictive evaluation method and device of a ship integrated electric propulsion system. The method includes the following steps that: the ship integrated electric propulsion system ship is divided into a plurality of subsystems, and all the sub systems are divided into a plurality of units; the failure rates and repair rates of all the units are calculated; the topological model of the ship integrated electric propulsion system is established; load flow calculation is performed on the ship integrated electric propulsion system under a normal working condition and a non normal working condition based on the topological model, so that risk evaluation results can be obtained; and the risk evaluation report of the ship integrated electric propulsion system is obtained according to the risk evaluation results. With the method and device of the invention adopted, the accurate risk evaluation results of the ship integrated electric propulsion system under different working conditions can be obtained, and therefore, a foundation can be laid for the improvement the performance of the ship electric propulsion system.

Description

technical field [0001] The invention relates to the technical field of power system risk assessment, in particular to a method and device for risk prediction and assessment of a ship's comprehensive electric propulsion system. Background technique [0002] There are roughly three types of power system risk assessment methods: deterministic assessment, probability assessment and risk assessment. The deterministic method only pays attention to the detection of the most serious accidents, and the determined system operating point is too conservative. The probability assessment method considers the probability of accidents, but does not consider the economic losses caused by accidents, and does not coordinate the relationship between safety and economy well. The advantage of the risk assessment method is that it combines the probability of accidents with the consequences (such as economic losses, etc.), and quantitatively reflects the economic safety indicators of the system by...
