【摘要】：直流风电场内网中直流风机的串联被证明是一种有潜力的大规模海上风能汇聚方案。然而,直流风机电压限幅期间的弃风现象是制约直流串联型风场商业化的主要因素。描述了海上直流风场内网中串联直流风机的耦合特性。为减少弃风,提出了电压限幅下串联直流风机的变速控制策略。为实现风场级研究中的所有控制,建立了含机电暂态特性的直流风机平均值模型。仿真算例结果,验证了所提策略的有效性。
[Abstract]:The series of DC fan in the inner network of DC wind farm has proved to be a potential large-scale offshore wind power gathering scheme. However, the abandonment of DC fan during the voltage limiting period is the main factor restricting the commercialization of DC series wind field. The coupling characteristics of a series DC fan in an offshore DC field network are described. In order to reduce abandonment, the variable speed control strategy of series DC fan with voltage limit is proposed. In order to realize all the control in wind field research, an average value model of DC fan with electromechanical transient characteristics is established. Simulation results show the effectiveness of the proposed strategy.
