Fast Real-Time Data Exchange among Distributed Control System of STATCOM Installation

Power installations based on power converters in power transmission and power distribution require real-time control which is usually implementing using multiple control units. Therefore, very fast data exchange within constant sampling periods across whole control system is needed. This paper deals with the development and implementation of a specific communication protocol for an embedded modular control system. The communication protocol employs LVDS bus and it is designed for fast data exchange between master and slave control units. The protocol is used in control system REMCS of a STATCOM of 1.35MVA installed in distribution power grid of 22 kV.
