| Abstract: | Proposed a multi-channel ac sampling method for microprocessor protective relaying of low-voltage distribution network, which based on C8051F020 as control core and sequential sampling to approximate realize simultaneous sampling. In the overall design scheme based on analysis, focusing on introduce a system hardware circuit of forward channel and a software programming flowchart. As showed in testing, the design method can meet the need of sampling signal for the microprocessor protective relying of low-voltage distribution network. |
