| Abstract: | Taking the Digital Signal Processors(DSP) as the control key,the intelligent protection device of the electric grid in the underground mine based on the DSP is designed.The protection device lays special stress on solving the phase sensitive short circuit protection,thermal overload inverse time protection,directional power leakage protection and other problems that long term plagued grid reliability operation.Experiments show that the protection device is reaction sensitive and reliable operation. |
