在衡量交直流耦合程度时,在考虑扩展延伸后的交直流相互作用因子的基础上还综合考虑了潮流转移因子的影响,对其进行归一化处理后新定义了指标——直流综合支援因子,然后将其映射为支援策略的优劣排序。以某电网不同断面发生故障为例,通过计算各条直流所对应的直流综合支援因子得出支援策略。介绍了仿真计算验证结果。
In measuring AC /DC coupling,this research takes into account the expanded AC /DC interaction factors,as well as the influence of power flow transfer distribution factors,then the normalized indicators are defined as DC comprehensive support factors,mapped in support strategy order.Take a grid with different cross-section failures as an example,calculate the DC comprehensive support factor for each DC power and derive support strategy.Simulation verification results are finally introduced.
