<br />001698 <br /> <br />feet and direct7connected to a <br /> <br />kilovolt-!lllIpere <br /> <br />t~~e generator with direct connecte~ excitp.r and pilot exciter. <br /> <br />Water would be supplied to each turbine through a steel penstock ~prox- <br /> <br />imately 1,400 feet long, wit~ synchronous bypasses provides so that the <br /> <br />flow through the penstock can be discharged either through the turbines <br /> <br />or the bypasses into the Twin Lakes Reservoir. ~he b~~asses would be <br /> <br />mecharlicaJ.ly cOll1',ected to the turbine gats operating mechanism sO that <br /> <br />rapid gcverning of the units under varying load conditions can be <br /> <br />effected without creating exceseive water hammer. Trashracke with <br /> <br />shut-off gatee for each penstock would b~rovided in the forebay struc- <br />I <br /> <br />ture. The headgate would be controlled from the powerplant. A epill- <br /> <br />way would be provided to care for the flow when the headgatee are <br /> <br />closed and the penstocks inoperative. The plant >lould be e<'tutpped wi tb <br /> <br />all necessary auxiliarie s, 1ncl uding a traveling crane for, handling the <br /> <br />large pieces of equipment. A small machine shop would be provided for <br /> <br />making minor repairs. An outdoor type 6Ubstation with self-cooled <br /> <br />transformers would be provided for stepping the voltage up to <br /> <br />for transmission to cOMmercial markets. The substation structure would <br /> <br />be of the conventional etructural steel type with high voltage oil <br /> <br />circuit breakers, lightning arresters, and necess~ry auxiliaries. The <br /> <br />control of the oil circuit breakers would be from the main powerplant <br /> <br />owitchboard. Operators' ttUarters, a >larehouse, and a large machine <br /> <br />shop for general project repairs would be provid,ed in the vicini ty of <br /> <br />the powerplant. <br /> <br />41 <br />
