| Abstract: | A monitoring scheme based on the hierarchical and distributed structure is put forward for the DC power system of the small and medium power plant and substation.It takes the three layers monitoring modes,the local monitoring unit,the local monitoring center and the remote monitoring center.The local monitoring unit is divided into some distributed module boards by function,each module board employs enhanced MCU as the control core,and it has an open architecture.The local monitoring center is composed of a... |
