Description / Abstract:
This guide addresses the application, design concepts, and
implementation of computer-based control systems for hydroelectric
plant automation. It addresses functional capabilities, performance
requirements, interface requirements, hardware considerations, and
operator training. It includes recommendations for system testing
and acceptance. The electrical protective system (generator and
step-up transformer) is beyond the scope of this guide.
Purpose
This guide is directed to the practicing engineer who has some
familiarity with computer-based control systems and who is
designing or implementing hydroelectric unit or plant control
systems, either in a new project or as a retrofit to an existing
one. Although this guide is aimed primarily towards large
hydroelectric power plants, many of the concepts are applicable for
small hydroelectric power plants (i.e. unit size 5 MVA or smaller).
Further details on small hydroelectric power plant control concepts
can be found in IEEE Std 1020™ [B46].1, 2 Typical
hydroelectric system control logic upon on which this guide is
based can be found in companion guide IEEE Std 1010™ [B45] or IEC
61362 [B22].3
