Abstract

Abstract:

Traditional substation automation system mostly uses single-chip computer as its internal core processor. This system not only has simple functions, but also has poor ability to deal with complex problems. In order to solve the above problems, a set of substation integrated automation control system based on DSP is developed in this paper. The system can monitor, measure, controls and coordinate the real-time operation status of substation equipment by analyzing and processing the collected data by DSP combined with communication and computer technology. Experiments and test results show that the automation system can better complete the functions of automatic monitoring and control of secondary equipment in substation, and significantly improves the efficiency of data transmission and sharing among electrical equipment in substation.

Key words: digital signal processing, A/D conversion, measurement and control and protection unit, communication network, automatic control
