10 kW<br />

Un sistema de distribution de 10 kW es sufi-<br />

cientemente pequefio de modo que 10s circuitos de<br />

voltaje secundarios pueden acarrear la energfa de<br />

salida. Como la unidad es tan peqaefia, el costo por<br />

kWh de 10s trabajos civiles, la turbina y el generador<br />

posiblemente ha de ser muy elevado. En consecuen-<br />

cia, la distribution electrica debe ser tan simple y<br />

barata <strong>com</strong>a fuere posible. El centro de la carga para<br />

este sistema pequefio debe estar ubicado dentro de1<br />

radio de un kilometro de la ubicacicin de1 generador<br />

para limitar la caida de1 voltaje. Los lugares para<br />

este tamario potential con un centro de carga que<br />

diste m&s de 1 km muy posiblemente no se&n<br />

factibles.<br />

1000 kW<br />

A 1000 kW system is large enough to justify<br />

additional facilities for improving service reliabili-<br />

ty. The station should have more than one<br />

primary feeder and may provide an alternate<br />

feeder for key loads. Figure 4 is a one line<br />

diagram of a three phase 1000 kW system with<br />

an alternate feed to the village load.<br />

Interconnection With an Existing<br />

Distribution System<br />

Interconnecting a small hydroelectric generator<br />

to an existing distribution system must be done<br />

with regard to the safety, electrical protection,<br />

and service quality of the existing system.<br />
