摘要
传统交流供配电系统具有谐波污染大、电压波动等问题,直流配电系统是解决上述问题的有效途径。直流配电系统目前正处于发展初期,众多问题亟待研究及解决。其中直流线路的保护问题是系统安全稳定运行的保障。本文分析了无通道保护在直流配电系统中的应用可行性,研究并设计了直流配电线路的无通道保护方案,并对所研究保护方案的可行性进行测试分析。结果显示本文所研究的基于无通道保护的直流配电线路保护方案能够快速识别并切除故障。
The traditional AC distribution system has the disadvantages of large harmonie pollution and voltage fuc tuation,while the DC power distribution system is an ffective way to solve the problems.Al present,the DC distri bution system is in the initial stage of development,and many problems need to be studied and solved urgently.The protection of DC line is the guarantee of safety and stable operation of the system.It analyses the feasibility of the application of non-channel protection in DC distribution system,studies and designs the non-channel protee-tion scheme for DC distribution lines,and tests and analyzes the feasibility of the protection scheme.The results show that the DC distribution line protection scheme based on non-channel protection scheme can quickly identify and remove faults.
