Research Of Leakage Protection Configuration For Rural Low Voltage Power Network

Material condition of realization of leakage grading protection is provided bycompletion of large-scale upgrading and rebuilding of rural low voltage power network.Technical support is provided for realization of grading protection for application ofnewly-multifunctional protector. Organizational guarantee is provided for realization ofgrading protection for reformation of rural power system. Leakage protection of rurallow voltage power network is configured rationally. It helps to enhance powerconsumption level, decrease leakage fault, improve service ability and change powerconsumption status, fit development and reformation of rural low voltage power network.Firstly importance of the topic and research situation of digital substation at homeand abroad, recent development of leakage protection of rural low voltage powernetwork are introduced in the paper. Secondly leakage protection theory anddevelopmental stage, work principle, classification, national standard, performanceparameter and range of application of leakage protector are explained. Thirdly groundingproblems, grounding mode and methods of leakage protection are studied. Finallyoptimal configuration implementation plan of leakage protection of rural low voltagepower network are studied. Optimal configuration methods and implementation plan ofleakage protection are introduced in detail. The necessity of optimal configuration ofleakage protection for rural low voltage power network is verified.
