Laboratory testing of the communication based protection relays

The proper operation of control and protection applications in Substation Automation System (SAS) demands very high-speed and reliable communications that has being achieved by using IEC 61850. Moreover, the practical implementation and testing of protection scheme requires a communication system that can be conventional or high-speed peer-to-peer communication. This paper presents the evaluation of the performance advantage of GOOSE (Generic Object Oriented Substation Event) message over its conventional hard-wired counterpart for the same relays protection

Monitoring prašného spadu v průmyslové zóně města Jihlavy k.ú. Hruškové Dvory

Monitoring sledoval intenzitu prašného spadu v průmyslové zóně města Jihlavy - k.ú. Hruškové Dvory během dvanácti měsíců z důvodu zjištění zatížení této oblasti prachovým spadem. Byl určen dominantní zdroj znečištění a byla provedena kvantitativní analýza prašného spadu
