ZIV is a pioneer in the Substation Automation field, harnessing the resources and information available in microprocessor based IEDs.

Automation Systems are proven to:

• Minimize Losses (Reactive power control, load control ...)
• Reduce Black Out time
• Automate Service Restoration (without human intervention)
• Provide System Monitoring and Supervision

ZIV's concept of Integrated Protection & Control Systems has been field proven in more than 250 installations worldwide. Protection & Control integration is the cornerstone of efficient substation automation.

These are the basic building blocks of Protection & Control Integration:

Protection & Control IEDs

Modern IEDs provide great savings. A single IED provides the functionality of a traditional panel, reducing wiring and components. The IED protective functions are independent of the control module.

Substation Central Unit

To effectively harness and utilize the information provided by the IEDs, the Central Unit is in charge of the following tasks:

• Communication management
• Protocol emulation (master / slave)
• Logic and interlocking
• Substation automatic controls
• Real time data base
• Alarms and events managing
  

Substation HMI & Engineering Desk

The substation HMI provides real time monitoring and control of the system. The combined sequence of events records (SER) is an effective tool to analyze ocurrences in the system. In addition to the control functions (SCADA like system) the integration is completed by providing full access to the protection system (settings, records, and reports).

Outside the substation the HMI software doubles as a remote engineering desk.

Custom Data Management Software

High functional integrated systems are characterized by less physical elements, linked by effective communications. The main difference is the high volume of information generated. Systems would not be completed without the required tools to process this information.

Seamless communications

Communication requirements become critical when automation functions are in place. ZIV expertise in electronic design for harsh substation environment is applied to create reliable communication equipment.
