Risk evaluation method and apparatus for integrated electric propulsion system

Abstract

The invention, which belongs to the integrated electric propulsion system field, provides a risk evaluation method and apparatus for an integrated electric propulsion system. The method comprises: a risk state of an index of a sub system layer and work data of an index of a unit layer are collected; for each unit of the unit layer, a target index of the unit layer is screened by using a feature weight algorithm according to the work data of the index of the unit layer and a risk state of an index of a sub system of a sub system layer which the unit belongs to; and on the basis of the target index and the risk state of the index of the sub system of the sub system layer which the unit belongs to, training is carried out by using a rapid learning algorithm and a risk evaluation model of each unit is obtained to form a risk evaluation module group, so that a risk evaluation result of an integrated electric propulsion system is obtained. According to the method, a risk evaluation result of an integrated electric propulsion system can be obtained rapidly and accurately.

Description

technical field [0001] The invention belongs to the field of integrated electric propulsion systems, and in particular relates to a risk assessment method and device for an integrated electric propulsion system. Background technique [0002] Integrated electric systems are developed from integrated electric propulsion (IED). The integrated electric propulsion device consists of three parts: power generation, propulsion, and marine auxiliary power supply. The pre-research of the IED program proved to have many advantages, but it was not the most reasonable solution, so the concept of integrated power system (IPS) was proposed in 1994. That is, the high performance and low cost of the future fleet will be achieved through the versatility of equipment, ease of implementation, and standardization. With the deepening of research, according to the requirements of surface warships and the requirements of propulsion power and marine auxiliary power of various types of ships, it is...

Moreover, there are relatively few studies on integrated electric propulsion systems. There are some studies on the risk assessment of land power grids, but there are few risk assessments on ship integrated electric propulsion systems, especially the data types of ship integrated electric propulsion systems. Many, difficult to process, poor accuracy
