STUDY OF TURBINE DESIGN, CONTROL SYSTEMS AND POWER PRODUCTION FOR SANTO ANTÕNIO PROJECT

CHOICE BETWEEN KAPLAN AND BULB TURBINES.

OPERATION LIMITATIONS BECAUSE OF LARGE VARIATIONS IN FLOW AND WATER LEVEL.

HYDRAULIC FORCES FROM TURBINES ON POWER HOUSE AND THRUST BEARINGS.

POSSIBLE SAND EROSION PROBLEMS.

POSSIBLE CONTROL PROBLEMS OF TURBINES.

MATERIAL QUALITY AND STANDARDS, BRAZILIAN PRODUCTION

6.6 m

24.9 m

Hydraulic forces on concrete.

OPENING NOT TO BE REDUCED (MAX. 3-5 mm)

8158 TONN

SAND EROSION

NORWEGIAN RESEARCH ON HARD SURFACE COATING

COATING OF RUNNER BLADES

FREQUENCY STABILITY ON POWER LINES ? LEIGHT WEIGHT GENERATORS, UNSTABLE TURBINES.

THE MOST IMPORTANT STANDARDS YIELDS:

FOR ELECROMECHANICAL EQUIPMENT: IEC NORMS ,	BULB TURBINES
= TUBULAR TURBINES IEC 61366-5

FOR STEEL CASTINGS: CCH 70-3

BRAZILIAN INDUSTRY MEETS THESE STANDARDS IN MOST CASES.
