Complete SAS for onshore wind farms in Andalusia (Spain)

Two new wind farms in Andalusia will have ZIV protection, control and communication systems

  • Location: Málaga & Cádiz, Andalucia, Spain
  • Substations: S/E La Escalareta II y S/E La Estancia
  • Promoter: Gamesa Energy
  • EPC: Isastur
  • Substation Automation System: ZIV

The wind farms will have twelve wind turbines, with a capacity of 32 megawatts (MW): nine turbines in La Escalereta II project in Malaga, and three turbines in La Estancia wind farm, located in Cádiz

Multifunction Protection in Medium Voltage Switchgear

Both wind farms will be maintained and operated by Siemens Gamesa for 20 years. They will have an ZIV integrated protection and control system, including multi-function protective relays installed in the medium voltage switchgear.
