The safety and stability of ship navigation mainly depend on the operation reliability of ship diesel generator. In order to improve the safety of ships in operation, it is necessary to study and analyze the reliability of diesel generators. Therefore, the research method of the operational reliability of the marine pulse load diesel generator is proposed. By establishing the mathematical model of the marine pulse load diesel generator, the operational status of the diesel generator is obtained. Based on this, the operation reliability index of marine pulse load diesel generator is selected, and the state subspace of the generator is established by the nuclear principal component analysis method in combination with the above reliability index. The main included angle formed by the basis vector of the state subspace in the normal and current state of the generator is extracted, and the operation reliability of marine pulse load diesel generator is obtained by combining the mapping function. The experimental results show that the state detection accuracy and reliability analysis accuracy of the proposed method are high.
