Substation Automation Systems (SAS) for transmission and distribution digital substations
ZIV designs, manufactures and installs robust and flexible solutions for integrated protecion, control and telecommunication systems.
Our support centers provide engineering services based on experience and latest tecnhology to optimize the cost and resources of every single project, based on:
Today, information flows constantly and in a great amount of Mbytes between protection relays, bay control units, substation gateways, etc… comprising the so-called STATION BUS. Primary equipment, such as circuit breakers, CTs and VTs, will also be connected to this flow of information: the PROCESS BUS. This is the new fully Digital Substation and ZIV is ready to support you with it.
IEC 62351 and IEEE 1686-2013 standards
RBAC, secure keys, physical and logical port disabling, cybersecurity event log, and securing of management protocols (PROCOME, HTTPS, SFTP, SSH)
The wide and commonly accepted presence of internet-based technologies into the transmission systems has led to evident advantages in the assets management. But the communication standards running over TCP/IP represent a potential risk of fraudulent access to the IEDs in the network so CYBERSECURITY raises as a must and ZIV, aware of this new scenario, keeps working on it.
Continuous improvements in communication technologies and software tools enable utilities to use SYNCHROPHASOR SYSTEMS as the most effective and accurate way for the preventive detection of critical faults within the power network systems. ZIV plays an active role in this field participating in international working groups focused on this subject.
