±500 kV柔性直流电网控制策略研究
|
摘要
文中针对±500 kV柔性直流电网的控制策略加以分析研究,并使用时域仿真的手段加以验证。针对张北柔直电网换流器控制策略,其要避免接入短路比在1.3以下的弱交流电网;直流电网的系统级控制非常重要,要兼顾系统稳定与换流器过负荷两方面的要求;由于直流电网配置线路直流断路器,可以利用合直流断路器来为其他换流器充电;对于直流电网可以通过配置快速合环开关来实现换流站退出后的线路潮流快速合环。
In this paper,±500 kV flexible HVDC grid control strategy is researched and analyzed. The converter is need to avoid connecting to the weak AC grid under SCR less than 1.3 according to converter level strategy. The system strategy is very important and it must focus on both system stability and converter overload. The rated voltage converter can charge for the other converters by DC break and the disturbance should be acceptable. The rapid close loop switches can be installed to loop the DC grid line flow.
