Research on the current differential protection where PV access to the high voltage distribution network with T-type
摘要
Abstract
The characteristic of fault current of photovoltaic power is analyzed. Research on the problems that two traditional criterions of current differential protection used in photovoltaic T-type line has done and results show that traditional criterions cannot simultaneously meet the sensitivity and reliability. Combining with the characteristic of fault current of photovoltaic power, a synthesis criterion of current differential protection suitable for photovoltaic T-type line is proposed. A lot of simulation has done and simulation results show that the synthesis criterion can not only satisfy the sensitivity and reliability but also has a strong resistance to the fault resistance.关键词
