摘　　要：对油田分布式光伏并网系统进行建模仿真,得到不同故障状态下的电源回路电流突变量和正序电流相位差,以及负荷扰动时的电源回路电流突变量,对基于正序功率方向的逆功率保护和基于正序电流相位比较的逆功率保护分别进行分析。通过仿真研究,确认逆功率保护在油田分布式光伏并网系统中的适用性和有效性。The modeling and simulation of distributed photovoltaic grid connected system in oilfield were carried out to obtain the current sudden changes in power supply circuit and positive sequence current phase differences under different fault states,as well as the current sudden change in power supply circuit under load disturbance.The reverse power protection based on positive sequence power direction and the reverse power protection based on positive sequence current phase comparison were analyzed separately.Through simulation research,the applicability and effectiveness of the reverse power protection in distributed photovoltaic grid connected system in oilfield was confirmed.
