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

SGS-2021-021Power 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

A comparison of histological and chemical analysis in mechanically separated meat

The aim of this study was evaluation of quality of mechanically separated chicken meat (MSCM) samples obtained by three different separators, by means of a histological (qualitative and quantitative) and chemical examination. Histological examinations used Green Trichrome and Alizarine red staining. The examination was focused on the evaluation of muscle, fat, collagenous connective tissue, bone fragment and calcium content and on the degree of damage to the muscle fibres. Chemical analysis was focused on calcium-, fat- and collagenous connective tissue content. The product obtained by the separator 1 (hard separation) gave similar good results to the separator 3 (soft separation), while separator 2 (hard separation) gave worse results as for being bone fragments and calcium content. As demonstrated, the quality of the product obtained by the separator 1 has improved over the years. The results of the histological analysis were in accordance with the results of chemical analysis. For the quantitative determination of collagen, calcium and bone fragments, image analysis was used. In the present study, good correlation between quantitative histological analysis and chemical analysis was observed (0.673, 0.718 and 0.809, α = 0.01)

Distributed control system for medium-voltage STATCOM based on parallel connected power converters

Power semiconductor installations in mediumvoltage power grids are usually built by numerous particular power converter units containing large number of power modules. Such large installations place high demands on control systems including precise timing and signal distribution across the whole system. This paper deals with a proposed distributed modular control system designed for STATCOM installed in a MV power grid of 22 kV. The proposed control system is designed for a real-time control of the converter with high-speed interference-immune communication, reliable synchronization of numerous PWM outputs and synchronous immediate blocking of fire pulses for safe central stop in case of error handling
