ETAP Intelligent Load Shedding Deployed at One of Indonesia’s Largest Copper-Gold Mines

PT Newmont Nusa Tenggara uses the ETAP enterprise solution to monitor, control and optimize its electrical power generation and transmission.

Operation Technology, Inc. (OTI) has announced that PT Newmont Nusa Tenggara (PTNNT), operator of one of Indonesia’s largest copper-gold mines, has successfully deployed the ETAP Real-Time enterprise power system solution to reduce production losses due to faults caused by a variety of environmental disturbances. In addition, PTNNT is using ETAP Real-Time to monitor, control and optimize power generation and transmission at its facilities throughout Indonesia’s Sumbawa island.

PTNNT’s installation of ETAP Real-Time employs two primary products: ETAP Intelligent Load Shedding (ILS) and ETAP Power System Monitoring & Simulation (PSMS). Together, these products provide PTNNT with a fully integrated system to optimize electrical power management, resulting in lower generation cost and fewer process time losses due to unnecessary load tripping.

For this project, the heart of ETAP Real-Time is ILS, an advanced product that uses artificial intelligence to dynamically determine the optimal system response to a variety of system changes and disturbances. ILS evaluates electrical and physical parameters, network topology, control logics and system operating conditions (loading, generation, etc.) to determine the best load shedding priority, based on the type and location of the disturbances. ILS provides faster execution of load shedding, as compared to conventional frequency relays, further reducing the load relief requirements.

ETAP Real-Time has been operating at PTNNT for more than six months. According to Ilyas Yamin, GF Power and T&D Maintenance Engineer for PTNNT, ETAP ILS is the most intelligent load shedding system available compared with any other products on the market.

The development of ETAP ILS was a major defining milestone for OTI, stated Dr. Farrokh Shokooh, President and CEO of OTI. “We have developed many new state-of-the-art products in our 20-year history, but ETAP Intelligent Load Shedding stands out as one of our greatest achievements,” Shokooh adds. “ILS has broken new ground in power management technology by providing the intelligence and speed required to minimize the detrimental effects of system disturbances. We are extremely proud to see ETAP ILS in action.”
