Thyristor exciters and synchronous machines
Process type: control of synchronous motor starting and control of its filed current
Industry: mining
Design and implementation: Apator Control Sp. z o.o. / Carboautomatyka
Automation system: One-way Mentor II 350 A Control Techniques drive, PLC MD 29 card
Date of implementation: July 2006
Goals:
- design of electro automation system for synchronous machine
