An important maintenance project has been started in the hydroelectric power plant of Ceppo Morelli, in Valle Anzasca, on the \u201cGR1\u2033 generator. In order to improve energy efficiency and to maintain the high standards of functional safety of the generator,<\/strong> the process of replacing the 2 Pelton turbines<\/strong> has started, which were installed in 1982 and still in operation. The operation, launched in July 2021 with a capex of \u20ac 250k, will be performed in March 2022. <\/p>\n

Hydrochem Italia has always felt strongly about the energy and environmental sustainability<\/a><\/strong> of their systems since its first construction in the 1940s. The first power plant was Megolo (1941), powered by the river Toce in Prata, where the intake from the river had a barrier consisting of 6 gates and a \u201cfish ladder\u201d to allow the native fish species to continue their migration. <\/p>\n

The Ceppo Morelli hydroelectric plant, the subject of the current project, started operating in 1948, drawing from the waters of the Anza and Quarazza rivers.<\/p>\n

Ceppo Morelli has 2 hydroelectric functional units:
\n1) 2 horizontal Pelton turbines <\/strong>of 7500 kW (3750 kW per turbine), with a Tecnomasio Brown Boveri three-phase synchronous alternator 9 MVA 2300 V, called GR1 \u2013 to be replaced in 2022.
\n2) 1 4000 Kw horizontal Pelton turbine, <\/strong> with a 1947 Tecnomasio Brown Boveri three-phase synchronous alternator, 4.5 MVA 2300 V, called GR2 \u2013 that was replaced in 2002.<\/p>\n

There are various and far-sighted reasons for this decision:<\/p>\n

1. Machine safety<\/strong>: since their early use, the turbines have been monitored annually, at each downtime in the winter months, with checks for thickness and cracks on each turbine blade, and after 40 years of activity they have reached the end of their functional life.<\/p>\n

\"\"<\/p>\n

. 2. Energy increase:<\/strong> the replacement will allow a gain of approximately 5% of the nominal power, a 7200 KW unit to cosfi 0.8. After replacing the turbines with others of modern hydraulic format, the turbine efficiency, at full load, could reach 89%.<\/strong> <\/p>\n

\"\"<\/p>\n

This operation is looking beyond the short-term benefits. In fact, the imminent replacement of the turbines will assure a high level of safety for the entire hydroelectric plant for at least another 40 years. <\/p>\n","protected":false},"excerpt":{"rendered":"
