基于DSP的矿井下电网过电流保护配置方法

Over Current Protection Collocation Method of Electric Grid in Underground Mine Based on DSP

摘要: 采用数字信号处理器（DSP）作为保护装置的控制与数据处理核心，设计了基于DSP的矿井下供电网过电流保护装置。该过电流保护装置重点解决了矿井下联络线路的过电流保护、终端线路的过电流保护及其相应线路过电流保护配置方法的问题,实践证明该过电流保护装置反应灵敏、动作可靠。

Abstract: The Digital Signal Processors (DSP) , as the control core of the protection device, is applied to design over current protection system of the electric grid in the underground mine based on the DSP. The protection device lays special stress on solving the over current protection of the tie lines and the tag wires and other corresponding lines. The protection device would have reaction sensitive and reliable operation.
