Transient Interaction of HVAC and HVDC in Converter Station in HVDC, Ⅲ: Effects of AC Sides on DC Sides
摘要
Abstract
The AC-DC system electromagnetic transient interaction of nanoseconds, microseconds, milliseconds electromagnetic transient due to AC-DC system operation and fault, the DC converter valve movement, and the load generated by changes can pose a hazard on AC and DC power systems, in particular, lead to the commutation of DC system failures and serious incident of atresia. Consequently, on the basis of the broadband characteristics model which can accurately reflect the existing AC-DC interconnected system electromagnetic transient characteristics of the key components, we apply the PSCAD / EMTDC platform to build a computational model, and reveal AC side electromagnetic transient interaction on DC side. The results show that the electromagnetic transient effects of AC side on the DC side are more serious, three-phase short circuit fault of 330 kV AC converter station bus occurs when the DC polar-to-ground over-voltage across the valve reaches the 1000 kV, more than insulation level of protection of the design value.关键词
