Valve automation at CCGT plant

Jon Lawson

The new Valle de México II combined cycle power plant, situated in the northern outskirts of Mexico City, relies on the latest AUMA valve automation technology.

The new 615MW combined cycle gas turbine (CCGT) block has been equipped with 136 AUMA SA multi-turn electric actuators equipped with AC intelligent actuator controls and gearboxes. The operator, Comisión Federal de Electricidad (CFE), had already adopted AUMA actuators for the plant’s first power block more than 15 years ago and has been happy with their performance and reliability ever since.

For the new block, local AUMA staff mounted and commissioned the actuators in the first half of 2018. The actuators were successfully integrated with the DCS in a Foundation Fieldbus environment using customised electrical connectors. The company also provided explosion-proof actuators that were installed in the vicinity of the gas turbine.

AUMA has only recently expanded its global sales and service network by opening a new subsidiary in Mexico City. Jorge Guerra, director AUMA México Andina y Centroamérica, reports: “The new office confirms our commitment to provide our customers with local service and support in this commercially very active region.”
