THE RPS DAM ( HEPS) IS PART OF CHAMBAL PROJECT .

THIS PLANT WAS OFFICIALLY DECLARED OPEN ON 9FEBRUARY 1970 BY INDRA GANDHI.

THIS DAM IS USED FOR BOTH IRRIGATION ANDGENERATION OF ELECTRICITY. THE TOTAL DAM LENGTHIS ABOUT 1 KM AND 25 FEET WIDE.

RPS HYDRO POWER PLANT CONSIST OF FOUR UNITSOF EACH 43 MW.

THE GENERATED VOLTAGE IS 11 KV ANDTRANSMISSION VOLTAGE IS 132 KV .

GENERAL DESCRIPTION OF RPS HEPS

AT RPS HEPS 4 UNITS OF FRANCIS TURBINE AREINSTALLED & EACH TURBINE ROTATE AT 125 RPM.

GENERATOR IS DIRECTLY COUPLED WITH TURBINE,GIVING OUTPUT OF 43MW AT 11KV & 50HZFREQUENCY.

THE OUTPUT VOLTAGE IS STEP UP TO 132KV BYTRANSFORMER.

THE PLANT OPERATED AND CONTROLLED FROMCENTRALIZED ROOM WHICH IS HAVING ALL THEINFORMATION RAGARDING DIFFERENT SYSTEMS OFPLANT.

HYDRAULIC TURBINE

THE RPS HEPS IS LOW HEAD POWER PLANT SO FRANCIS TURBINEIS USED.

IT IS A REACTION TURBINE.

THIS TURBINE DEVELOPS POWER PARTIALY DUE TO VELOCITYOF WATER & PARTIALY DUE TO DIFF. IN PRESSURE.

IT CONSIST GUIDE APPARATUS WITH AN OUTER RING OF

STATIONRY BLADES & INNER RINGS CONSISTING OF ROTATINGBLADES FORMING A RUNNER .

THE EFFICIENCY OF TURBINE VARIES IN 80% TO 85%.
