海上平台由于远离陆地,无法使用陆地电网供电,都是采用平台自发电。平台电网相对较小,而装机容量逐渐增大,平台上大功率感性负载的频繁启停,会产生谐波,对平台电网冲击较大。本文研究利用有源电力滤波器降低平台上大功率设备较多的钻机模块工作时产生的谐波,以保护平台电网,从而实现安全生产。 Because offshore platform can not use terrestrial power supply because it is far away from land, platform is used to generate electricity. Platform power grid is relatively small, and installed capacity gradually increased, the platform of high-power inductive load frequently start and stop, will produce harmonics, the greater impact on the platform power grid. This paper studies the use of active power filter to reduce the platform of high-power equipment more rigs work generated when the harmonic module to protect the platform power grid in order to achieve safety in production.
