Embodiment Construction
[0028] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0029] for figure 1 A bipolar DC transmission system is shown, including: a rectifier converter station and an inverter converter station, which are connected by two DC transmission lines, wherein: the rectifier converter station is used to convert the three-phase AC power of the sending end AC power grid After the DC power is transmitted to the inverter converter station through the DC transmission line, the inverter converter station is used to convert the DC power into three-phase AC power and then transmit it to the receiving-end AC power grid. Passive filters may or may not be connected to the incoming bus of the AC power grid at the sending ...
