摘要 首先,采用含有分布式光伏电源和风机的"手拉手"多端柔性直流配电系统,分析了系统的关键设备并确定了接地方式和各端口协调控制策略。其次,为避免系统启动过程中出现过流现象、保护电力电子设备的安全,提出了一种柔性直流配电系统的启动控制策略。然后,提出了一种保护系统与控制系统的协调策略,以确保故障被隔离后,非故障区域能够正常运行。最后,采用PSCAD/EMTDC仿真分析了柔性直流配电系统的启动和正常运行过程以及故障发生时系统运行方式的切换,验证了柔性直流配电系统启动控制和运行方式转换策略的正确性。 Firstly,A"hand-in-hand"multi-terminal FDCDS which contains photovoltaic cell and wind turbines is adopted for further analysis of key equipment,and the grounding mode and coordination control strategy of each terminal were verified. Secondly,a new start control method of the FDCDS is proposed to protect the power electronic equipment from the overcurrent while the system starts up. Then,a coordination strategy of protection system and control system is put forward. And this strategy can make sure the non-fault areas function normally when the fault area is isolated. Finally,the startup control method,the normal operation,and the switching of operation modes when fault happened are analyzed by using the PSCAD/EMTDC software. The results indicate the validity of both the startup control method and the switching strategy of function modes of Flexible DC Distribution System.
