Abstract
With the large-scale construction of UHV DC power transmission projects, the correlation between AC and DC systems will be further enhanced, and the interaction between AC and DC fault will become increasingly complex. In this paper, taking ±800kV DC system from Xiangjiaba to Shanghai for example, the power downhill event occurred in trans-regional DC power network is simulated, and based on the comparative analysis on actual event, during which the security and stability control equipments act or do not act, the influences of action and no action of security and stability control equipments is discussed. From three aspects, I.e., planning and construction, technology application and operational control, the measures to mitigate the impact of fault occurred in DC power transmission system on AC power transmission system are explored.关键词
