资料介绍

本文提出了一种以C8051F020为控制核心,以顺序采样来近似实现同步采样,适用于低压配电网络微机继电保护的多通道交流采样方法。在对总体设计方案分析的基础上,重点介绍了系统前向通道硬件电路设计以及软件编程流程图。测试表明,该设计方法能够满足低压配电网络微机继电保护对采样信号的要求。

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.
