Principles And Practice, Dsp-based Integrated Management System Of Distribution Transformer Terminal

The remote terminal unit (RTU) for distribution management system (DMS) has been developing to comprehensive automation equipment based on micro-computet-. It not noly has traditional data acquisition and communication functions also power quality detection and fault detection and local automatic supervise and control functions. This led to need of high performance RTU. With the technology of digital signal processing, constituting the structure of double CPU with micro-computer unit and digital signal processor is a feasible solution. With analyzing of the basics of general RTU. this paper brings forward the hardware and software design and realization of the high perforniance RTU based on the structure of above.
