Full Description

This document includes relevant technical data used to describe hydraulic turbine governing systems and to define their performance. It is aimed at unifying and thus facilitating the selection of relevant parameters in bidding specifications and technical bids. It serves also as a basis for setting up technical guarantees.

The scope of this document is restricted to the turbine governing level. Additionally some remarks about the control loops of the plant level and about interactions with the electrical grid in case of primary and secondary frequency control (see also Annex B and Annex C) are made for better understanding without making a claim to be complete.

Important topics covered by the guidelines are:
– speed, power, water level, opening and flow (discharge) control for reaction and impulse-type turbines including double regulated machines;
– means of providing actuating energy;
– safety devices for emergency shutdown, etc.

To facilitate the setting up of specifications, these guidelines also include data sheets, which are filled out by the customer and the supplier in the various stages of the project and the contract.

Acceptance tests and specific test procedures are outside the scope of this document; those topics are covered by IEC 60308.
