The development of DC on-line monitoring technology is the basis for the realization of CBM for DC Power. The key technologies of on-line monitoring system and its application of Southem Hebei power substation DC power supply were researched. Three grade construction scheme and system of DC online monitoring system at the provincial level, municipal, power plant was proposed. The date acquisition layer, data transparent transmission layer and the monitoring center management framework based on research data were introduced. A battery resistance of multi cycle group testing technology was researched, a kind of on-line remaining capacity testing method for battery based on state space prediction theory was proposed, and the key technology and the work flow of the system soltware was described. The system plays an important role to obtain the health status for DC equipment.
