Abstract: Distributed combined cooling heating and power (DES/CCHP) will be an important direction of power system development. With the increase of scale and capacity of the combined cooling heating and power system and integrating operation, the system safety becomes increasingly prominent. The lightning invasion wave can be one of the important factors which may influence the safety and stable operation of cogeneration station. An analysis is made on the electrical structure of CCHP cogeneration system in large civil airports. The ATP/EMTP software is used to simulate the overvoltage generated by a lightning invasion wave generated on the associated electrical equipment, and to analyze the impacts of different factors such as lightning strike point, the impulse grounding resistance and the arrester location on the overvoltage caused by lightning invasion wave. A solution scheme is proposed to install surge arrester in the low-voltage equipment side, which can provide a reference for the improvement of the lightning protection design for the union station.
