27-45 SISTEME DE MONITORIZARE ÎN CONDIŢII DE RISC A CENTRALELOR HIDROELECTRICE CU ACUMULARE PRIN POMPARE (CHEAP)

MONITORING SYSTEMS IN HAZARDOUS CONDITIONS OF HYDROELECTRIC PUMPED STORAGE (CHEAP)
The primary purpose of modern automation purposes of modern automatic control systems of hydroelectric plants are:
– Automatic adjustment of speed (frequency) and/or power energy group known as Automatic speed control systems (SRAV)
– Automatic adjustment of the voltage generator known as automatic control systems excitation (SRAE)
– Adjust the water level in the reservoir and swirled flow, depending on the spatial requirements
– Protection hydropower group to failures, defects or on the electric or hydraulic side.
Keywords: automatic control systems, automatic adjustment of speed, generator voltage
Cuvinte cheie: sistemelor de conducere automată, reglarea automată a turaţiei, tensiunii generatorului

21-32 O ABORDARE INFORMATIZATĂ ÎN DESCRIEREA PROCESELOR DINTR-O C.H.E.A.P.

ONE INFORMATIC APPROACH TO DESCRIBE THE
PROCESS FROM ONE HPP WITH STORING FACILITIES
In the conditions of today world wide rising price for conventional fuels,
the renewables and especially those of hydro power domain are coming to play
one more important role at higher efficiency. The most complex hydro power
plant HPP having storing energy facilities is already planned in our country into
the forseen future; it will be at the level of 1.000 MW/400 kV as rated power and
transmission voltage with the expected commissioning term-by the year 2020.
