Shared data acquisition system for real-time power systems applications.

摘要

Digital signal processing chip (DSP's) can be used to perform data analysis computation and have very good performance in real-time system. Digital filters can be designed with consideration of both magnitude and phase responses for digital re sampling in power system applications. The design consists of two parts: magnitude approximation and group delay compensation. It compromises between the amount of calculation needed to implement the filters and the performance of the filters, which makes the filters good candidates for both real-time and offline applications.
