The Spanish energy company Gas Natural Fenosa (GNF) has awarded to Eptisa a new contract to carry out the Automatization of the Auscultation Systems of the Edrada, Mao and Bolarque dams and Castrejón channel located in Orense, Guadalajara and Toledo.

The duration of the project execution is 6 months and includes all necessary works to equip the dams with an automated auscultation system. The Edrada and Mao dams will be equipped with PLC´s (Programmable Logic Controller) in each of the dams, which will collect the signals from the automated auscultation sensors and will be connected with a SCADA (Supervisory Control And Data Acquisition) application by the optic fiber network of GNF to dump the data to the corporate system PI (Plant Information de OSISoft) of the client. This application will be installed in a PC located in the Regueiro Hydroelectric Central, about 8 km from the Mao Dam.

In Bolarque dam will be installed two PLC’s, one in each river bank, to collect the signals from the auscultation sensors, connected with 5,8 Ghz WiMax link (Worldwide Interoperability for Microwave Access) between both left and right river banks and from this one to the Bolarque I Central. In this Central will be installed a display screen connected by the optic fiber network of GNF with the SCADA application to integrate it in the corporate system PI of the client, located in the Bolarque II Central.

Along the Castrejón channel of 16,6 Km long, which links the dam with the central, will be installed 13 water level gages to control the leakages, including the necessary civil works for the reconditioning and protection of them. These water level gages will be equipped with ultrasound sensors, powered by solar panels and connected by radio modem at 9600 bit/sec.

They will also have three new points of concentration that will be used as booster and will be equipped with the wireless connection WiMax, completing the network with two new WiMax equipments installed in the dam and in the water level gauge located close to the loading chamber (automated by Eptisa in 2012).

In this way, the wireless connection between the dam and the hydroelectric plant remains completed, which in turn will provide an alternative communications network between the PLC’s located in the dam and the SCADA application installed by Eptisa in 2012 in the hydroelectric plant and currently connected by VSAT.
