摘要
随着众多高压直流输电项目的建成投产,交直流混联电网逐渐形成,且在交流电网和直流系统中分别配有过电保护,以解决工频过电压的问题。但在实际应用中,却总因相互之间缺乏协调和配合,而引起不正确动作。鉴于此,文章结合笔者工作经验,举例浅析交直流混联电网的过电压保护。
AC/DC hybrid power grid gradually formed With the completion and commissioning of many HVDC Projects,and are all equipped with electrical protection In AC power system and DC system,used to solve the problem of power frequency over voltage.But in practical application,cause incorrect action because there is lack of coordination and cooperation between each other.For this purpose,In this paper,the author analyzed the overvoltage protection of AC/DC hybrid power grid combined with work experience.
