Embodiment Construction
[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0041] The network topology of the station integrated power supply system is as follows: figure 1 As shown, the entire substation low-voltage power supply equipment shares one IED file. The integrated power supply system IED adopts serial communication with DC power supply LD, AC power supply LD, communication power supply LD, UPS power supply LD and total monitor LD, and DC, AC, communication and UPS power supplies are connected to the integrated power supply system as logic devices LD middle.
[0042] The DL / T 860 standard stipulates for substation low-voltage power supply equipment: each minimum functional unit that needs to communicate is modeled as an LN object, and the data and data attributes belonging to the same functional object are placed in the same LN object, in order to ensure interoperability Therefore, it is not recommended to create a...
