Research on the Influence Factors and Limiting Methods for LightingOver-Voltage in Military Power Supply

Considering the characteristics of lightning protection for military motor power station and low technical performance of military power station lightning protection and weak objective etc., this paper, based on typical low-noise motor lightning in military power station, establishes the electromagnetic transient model containing key parts in the lighting protection, such as generator, control unit, and cables by the PSCAD/EMTDC power simulation software. The action mechanism and influence laws of indirect lighting over-voltage in the military power supply are discussed, and a technical proposal of the indirect lightning protection for the military power system is presented. This proposal is realized mainly by installing the SPD on the parts of the electric supply line, power supply line and signal line to provide shielding and filtering for the indirect lightning protection. This lighting protection module device is of high reliability and safety, and can overcome the barriers of the conventional lightening protection device, and helps to improve the indirect lighting protection capability and anti-weather fighting ability of the military power supply.
