A Common Embedded Digital Module for Power System Applications

摘要

This paper presents a common embedded digital module for use in various applications in power systems. The introduced digital module is capable of sampling a large number of signals and pieces of information, which are frequently required for control, protection, status evaluation and power quality monitoring of power systems. And it also gives the decision-making control and outputs. The digital module is based on the enhanced 16-bit digital signal controller (DSC), which combines the processing power of a DSP and the functionality of a microcontroller. The common digital modules embedded in different types of Intelligent Electronic devices (lEDs) in power systems can provide the reliability and security level needed for secondary system applications. The simplicity and integrity of DSC render the proposed scheme very attractive for a further cost decrement.
