基于扩展等面积法分析直流降功率速率对系统稳定性影响
Research on DC power reduction rate impact on system stability based EEAC
摘要
Abstract
High-voltage direct current transmission has a high transmission reliability, but when the high voltage grade ac lines connected to the inverter side out of service, we can choose non-blocking dc system, instead of using the low voltage grade lines which connected to the inverter side continue transmission power.However, this situation may cause inverter side to face the danger of overload, and meanwhile, it may reduce the stability of the system.In this paper, we adopted the way of dropping the DC operating power to avoid the possibility of happening the overload, and analyzed the mechanism of choosing the appropriate dc power reduction rate to increase the stability of the system which based on extended equal area method under fault condition.关键词
