Guide to Specification of Hydraulic Turbine Control Systems

Scope and object
This guide includes relevant technical data necessary to describe hydraulic turbine control systems and define their performance. It is aimed at unifying and thus facilitating the bidding specifications and technical bids. It will also serve as a basis for setting up technical guarantees.
In case of separate vendors for different segments of a system, the interface between them is especially important.
The guide is not confined to the control loop functions proper but includes all important functions of a control system, i.e., it also treats sequencing functions, etc. Hydraulic turbine control is thus understood to include:
- speed, power, water level and discharge control for reaction and impulse-type turbines including double regulated machines;
- means of providing actuating energy;
- safety devices for emergency shut-down, etc;
- environmental performance criteria.
The guide aids the selection of some important parameters to be specified and checked in relation to the different types of installations.
Excluded topics are acceptance tests, specific test procedures and guarantees.
