Embodiment Construction

[0046] The present invention will be further described below in conjunction with accompanying drawing:

[0047] combine figure 2 , taking the block diagram of the comprehensive assessment of the credibility of the medium-voltage electric propulsion system simulation as an example, the process of the comprehensive assessment of the credibility of the simulation system is divided into the following aspects:

[0048]VV&A (Verification, Verification, and Confirmation) technology is adopted as the principle of credibility evaluation of the simulation system to ensure that the comprehensive evaluation process of the credibility of the entire simulation system is completed on the basis of VV&A technology; according to the characteristics of the electric propulsion system itself, according to the system From level to unit level, the complex system is decomposed into several subsystems before analysis; according to the user requirements of the simulation system and the factors that af...

Abstract

The invention relates to the field of electric propulsion systems and simulation evaluation, in particular to a method of comprehensive evaluation for simulation credibility of an electric propulsion system. The method includes: disintegrating the electric propulsion system into subsystems; disintegrating the subsystems of the simulation system under various rules until minimum units are obtained; acquiring indexes and weights of the subsystems relative to upper level of nodes; acquiring credibility of the indexes of the subsystems to obtain the credibility of the subsystems; and acquiring results of comprehensive credibility evaluation for the whole electric propulsion system. The method has the advantages that correctness in output results of the established evaluation system can be enhanced and risks in development and application of the simulation system are lowered; developers are effectively aided in finding defects of design process of the simulation system and correcting the defects timely; development cycle of the simulation system can be shortened effectively, development cost of the simulation system can be lowered effectively, and important accidents in practical application of the simulation system can be prevented effectively.

Description

technical field [0001] The invention relates to the field of electric propulsion system and simulation evaluation, in particular to a comprehensive evaluation method for the simulation reliability of electric propulsion system. Background technique [0002] In recent years, simulation technology, as the most advanced science and technology, has been widely used in various research fields due to its advantages of good economy, high safety and strong operability, and it has also brought huge economic benefits. Simulation technology is also known as another new method of dissecting the real world besides theoretical research and physical analysis, and has become another technical means to correctly understand the objective world. Therefore, the use of simulation technology to study the actual system can not only effectively reduce the cost of scientific research, shorten the development cycle, but also speed up the pace of improving the performance of the actual system.
