摘要: 分布式冷热电联供(DES/CCHP)将是未来电网研究的一个新方向。随着冷热电联供系统规模、容量的增大,以及并网运行,系统安全运行问题日益凸显,其中雷电侵入波成为影响联供站安全、稳定运行的重要因素。分析了某大型民用机场的冷热电联供系统电气结构,然后,利用电磁暂态分析软件(ATP/EMTP)对该系统遭受雷电波入侵后在联供站电气设备上产生的过电压进行仿真计算,分析了不同雷击点、不同冲击接地电阻和避雷器安装位置等因素对雷电侵入波过电压的影响,并提出了在低压设备侧加装避雷器的解决方案,为改善联供站防雷设计提供参考。

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.

Key words: CCHP, integreated network operation, lightning wave intrusion, ATP-EMTP, civil airport, over voltage, simulation, lightning arrester
