32-6 DETERMINAREA PARAMETRILOR REALI DE FUNCŢIONARE A HIDROAGREGATELOR DIN CENTRALELE DE MICĂ CĂDERE

DETERMINATION OF THE ACTUAL OPERATING PARAMETERS OF THE HYDRO UNITS OF A LOW HEAD HYDRO POWER PLANT

 

The paper presents the flow rate calculation and measurement methodology for a high flow/low head hydro power plant with upstream cofferdam recesses.

At the same time, the paper presents the results of the in situ measurements of the actual operating parameters of the hydropower units, especially of the flow rate measurements carried out on the hydropower units’ no.1 and no. 2 of Robeşti HPP. The measurements have been carried out in agreement with the provisions of CEI 41/1991 [4].

 

Keywords:  discharge, efficiency, current meter method, hydro unit

27-56 CAPACITATEA DE ÎNCĂRCARE A UNEI CENTRALE HIDROELECTRICE ÎN FUNCŢIE DE NIVELUL ÎN LACUL AVAL

THE LOAD CAPACITY OF A HYDROELECTRIC
POWER PLANT BY THE LAKE TO DOWNSTREAM
In the paper presents the results of measurements of the tailrace of the hydroelectric power Șugag underground HPP (high head cents) to determine the maximum power that can be achieved with the safe operation of the plant by Şugag HPP capacity transport manifold run it. The paper presents how to perform monitoring and protection system for monitoring water levels in tailrace.

25-33 DETERMINAREA DEBITULUI TURBINAT LA O CENTRALĂ DE MARE CĂDERE

DETERMINATION OF TURBINE FLOW IN
A CENTRAL HIGH DROP
Optimal use of water resources in a hydro ensures both by design and
by the rational (optimal) planning installations.
Obtaining maximum power consumption for the same volume of water
is one of the ways to increase the efficiency of electricity production.
Keywords: yield, flow, the turbine gauging, the hydro-power plant,
hydroelectric turbine
