Time Synchronization in Electrical Systems with MEINBERG Equipment

Substation automation demands precise time synchronization for a variety of Intelligent Electronic Devices (IEDs). There are different possible approaches to achieve the required accuracy. Time synchronization for transmission substation integrated protection, system control and data acquisition require a target architecture that distributes the synchronized time in several ways. Different solutions are possible and can be realized using MEINBERG timing equipment.

Application of time synchronization in electrical systems Time Synchronization in:

SCADAs				->	Protocolization and registration

Communication equipment		->	Communication processors, 
					protocol translators

Protection relays		->	Fault and performance analysis

Faultrecorders			->	Post mortem analysis, 
					responsability, liability

Billingmeters AMR		->	Tarif switching, load analysis

IEDs, RTUs, SOE, Sensors	->	Protocolization + registration

Servers, Routers, Switches	->	IT security!

Frequency deviation		->	System stability

Security monitoring		->	Physical security

Digital voice and 		->	Civil responsability, Law,
video recording				Insurance companies
