Synchronization failure of Termoéléctrica Antonio Guiteras

The synchronization of theThermoelectric Antonio Guiteras, the largest generation in the country, failed when trying to incorporate it back into the national electroenergy system (SEN).

"Difficulties in the plant's automation are being investigated to re-synchronize," official journalist José Miguel Solís said this Sunday inFacebook, after having announced briefly before that the Matanzas thermoelectric plant had synchronized the SEN.

This Sunday morning, engineer Rubén Campo Olmos, general director of the unit,pointed outthat after carrying out maintenance on the plant, they were in the start-up phase and planned to connect to the SEN before peak demand time.

On that occasion he highlighted that it would be a "cold start" since the boiler was inspected and worked on, the turbine showed a good temperature and that condition allowed him to predict the entry on time.

The much predicted power of 250 MW that was expected to be achieved in a few hours never arrived.

Upon reconnection, it began to rise to more than 110 MW and gained power, but a problem in the plant's automatic system caused the synchronization to fail and it could never contribute megawatts to the decaying electro-energy system.

The thermoelectric plant left the national electroenergy system last Thursday tosolve some "defects" detected.

Overconsumption of water and other "defects that threaten the stability and performance of the plant" would be corrected.

Rubén Campos Olmos commented that the maintenance should last about 72 hours, to work on more than 20 valves and carry out hydraulic and hydropneumatic tests.

This Monday, according towarnedthe Electrical Union, unit 5 of the Mariel CTE, unit 1 of the Guiteras CTE and units 5 and 6 of the Nuevitas CTE are out of service due to a breakdown.

For peak hours, the entry of 154 MW into Distributed Generation engines is estimated, the entry of unit 5 of the Nuevitas CTE with 90 MW, recovery of 48 MW in the Mariel lake, the recovery of 36 MW in the Mariel lake. Melons and the recovery of 60 MW in Mariel fuel.

With this forecast, an availability of 2,664 MW and a maximum demand of 2,650 MW are estimated for the hour of highest demand, for a reserve of 14 MW, so an impact of 56 MW is forecast during this time if the expected conditions continue. .
