PROJECT TITLE :

Case Study: Smart Automatic Synchronization in Islanded Power Systems

ABSTRACT:

Automatic synchronizing systems are used to reconnect multiple islanded power grid sections. These systems are required to operate automatically with minimal human supervision because they have to dispatch multiple generators simultaneously to reduce slip and voltage difference at the interconnection purpose. This paper describes a good automatic synchronizing system that may connect multiple generators in an industrial Power System during islanded and utility-connected modes via six completely different bus-tie and utility tie breakers. The automatic synchronizing system performs matching by controlling multiple governor and exciter interfaces inside the power. Controlling slip and voltage difference across any of the six completely different breakers in any combination is accomplished with up to six completely different and simultaneous Power System islands. The facility system studied may be a giant refinery containing six generators, totaling about 260 MW of generation. The functionality, operation, and validation of this automatic synchronizing system using real-time-digital-simulator tests are mentioned.
